Cleaning Track Inside Tunnels

Maintaining track and keeping it clean is one of those jobs we all hate but has to be done to keep the trains running.  In this post, I’ll share with you how I clean the track inside the tunnel on my Tehachapi module.

Cleaning the track really only comes down to polishing the tops of the rails.  But there are lots of ways to do it and, depending on the severity of the dirt, some work better than others.  Under general running the nickel silver rails pick up all sorts of grime from the wheels as they pass over, whether plastic or metal.  Any rolling stock, such as locomotives or illuminated items that conduct electricity, cause a fine powdery oxide to form, due to the electrolysis effect; this is when current passes through dissimilar metals.  When you wipe your finger along the rails and get a black streak, that’s it.

The environment the layout is stored in also makes a huge difference.  If it’s in a dry space with a constant temperature, such as a spare room, the rails will stay fairly clean as the powdery oxide will simply fall off the rails.  But layouts in sheds, lofts, and cellars, where the temperature can drop or any dampness gets in, will cause the powdery oxide to bond together into a film and the rails will become dirtier sooner.

Also, any lubricants can run down and get spread over the rails causing locomotives to wheel spin.  Smoke oils and over-lubricated locomotives can cause this.

The stronger type of dirt on the track is usually caused by building the scenery.  Glues, paints, and lacquers will always get onto the track somehow and these take a bit more to remove.

Once I’ve finished the scenery I always give the track a good clean with an abrasive track rubber.  Lots of manufacturers make these; I don’t recommend using anything like emery paper or sandpaper as they are too abrasive. This initial clean is intended to remove any build-up that’s stuck on top of the rails.  If continually used the abrasive rubber, although very effective, will, over time, add lots of tiny scratches into the rail tops as it wears the metal down.  These scratches will hold the powdery oxide, and other dirt, onto the rails causing them to get dirtier even faster.  So for further cleaning, I use a cotton cloth and dipped Isopropyl Alcohol to wipe the railheads clean.  Proper Isopropyl Alcohol will evaporate leaving no residue.  Don’t use anything like WD40 as it will leave oil residue on the track.  Several companies make a solution specifically for this purpose.

But what about the tunnels?  As you may recall on my Tehachapi module I have a tunnel with curved track running through it.  The single track portal is too small to get my hand in so I can’t get a track rubber or a cloth in there.

My solution is to screw an old track rubber to a piece of long wood.  As the rubber is soft the screws sink in so they don’t stick out of the rubber and therefore can’t catch on anything, but it could also be glued on.

The rubber and timber want to be thin to allow movement inside the tunnel.

Using this I can then clean the rails inside the tunnel, first with just the rubber to remove any glue from the ballasting and later with the rubber wrapped in cloth and a drop of Isopropyl Alcohol.

I can get to all of the track inside the tunnel using this.  I just need to watch my hand on the signal which is close to the tunnel portal.

As we clean our track before each operating day at an exhibition I don’t want to forget the tool.  So I have built a holder inside the module to ensure it always travels with it.

Once you have good clean track another way to maintain it is to use track cleaning cars that you run around at regular intervals.  Some of these have abrasive wheels that run on the rails and some have cloths that you can add Isopropyl Alcohol too.  You can even get some with mini vacuum cleaners in.

Now that the Tehachapi module is mostly complete (I still have to finish the signals) I can turn my attention back to the 3D printed projects, some of which I’m hoping to finish soon and I’ll share them with you as they develop.

Solent Summit At Warley 2019

This year the Warley Model Railway Club held its annual exhibition on the 23rd and 24th of November 2019 at the National Exhibition Center in Bermingham and my club, the Gosport American Model Railroad Group, took our N Scale Layout ‘Solent Summit’.

‘Solent Summit’, unlike most model railways at exhibitions, is modular, which means we can increase or decrease the size and alter the shape to suit the space we’re given.  And for small shows being smaller makes the layout more manageable.  But given that the Warley exhibition at the NEC is one of the largest in the UK we took everything, well just about everything.

The space we had was 65′ by 26′ and we filled it with just under 5 scale miles of scenic sections; the yard space was not included in the length calculation.

To give you an idea of how big the show is, our layout, which was the largest in the show, is circled in red on the plan below.  We had a nice central spot.

We arrived on Friday at midday to set up, which took 7 hours.  Cottesmore Model Railway made this short video below showing the hall when we arrived followed by the crowds as the show opened on Saturday morning.  It gives some idea of the size of the show.

The configuration of ‘Solent Summit’ for this show was a large letter E with ‘East Yard’ being at the top and ‘West Yard’ at the bottom.  The mainline is a single track with three large passing places evenly spaced along the line.  This means that there are always five or six trains on the mainline at the same time.  There are several other passing places but as we run lots of long trains we needed to keep to the three main ones to avoid getting jammed.

The photo below shows the layout from the bottom right corner just before we got going on Saturday morning.

Given the size and all the new modules we had, I thought I would talk you through them all, starting at the East Yard.  The majority of the photos here have been taken by our friend Paul Begg who let me use them as I had very little time once the show was open, and he’s a better photographer than me!

The East Yard has 6 tracks with trains entering on the right and leaving on the left.  The combined storage shown here is 141′ 3″ of trains.  Typically we have three trains in each line. The ‘West Yard’ is the same size and trains will set out from each yard at the same time, pass each other at one of the three passing places and enter the opposing yard.  Once all the trains have swapped ends, we start again.  A few trains are special in that they exchange with other trains on the layout.  For example, a coal train can leave ‘West Yard’ and stop in the ‘Power Station’.  The engineer will then continue the journey with another train from the ‘Power Station’ to fill the space in ‘East Yard’.

Leaving the East Yard the twin tracks enter the scenic boards and the first is ‘East Fork’ which is a two-into-one board.  The M-10000 pictured below, often referred to as the Earth Worm, was built in 1935 for Union Pacific and was the first of their streamliners. It’s leaving the East Yard on its 5-mile run.

‘East Fork’, as you can see, ends with the standard single track. The lights on the side of the module indicate if the turnout is set for entry or exit; currently it’s set for exit.  They are repeated on the back of the module and help us see what’s going on from a distance.

The line now crosses a creek on ‘Rocky Creek’ built by Chris before entering ‘Tunnel 31’.

‘Tunnel 31’, built by Bob, has a small homestead with gravel roadway causing all trains to blow their whistles as they pass.  The module also has an automatic signal system triggered as trains pass through the tunnel.

Emerging from the tunnel we enter ‘Bob’s Pickle’ which is a double module.  This busy area, built by Bob, features several industries including Bob’s Blue Circle Pickles, Branstone Cement Works, Dunno-Watt Inc & King’s Scrapyard.  The complex also has a small passenger depot.  Running across the bridges is an overhead electric “inter-urban” shuttle service which runs a regular schedule between communities at the extremities of the module.

This module set can also be used for passing smaller trains.  The pickle works and cement factory are both kits from The N Scale Architect with 3D printed pickle cars, designed by me, and they can be found here.

Lurking at the back of the modules are the trio of Alco C-855s awaiting their next duty.

Leaving ‘Bob’s Pickle’ we enter the ‘Coal Mine’ also built by Bob.  The mainline runs through the tunnel nearest the front and three lines enter the coal mine for the loading of coal.

A UP Gas turbine with Alco FA & FB helpers sits on a train ready to go, as does a Big Boy on the far track.  This is one of the exchange points for other trains leaving the yard, but coal trains only exchange running West to East.  I’ll explain why later on.

As the mainline emerges from the tunnel it crosses ‘Hell’s Glen’, again built by Bob, which is a curved steel trestle over a deep ravine and a road before plunging into another tunnel.

As the mainline leaves the tunnel it enters ‘Power Station’, again built by Bob, which is home to the Solent Power & Light Company.

The interesting thing about these three modules is they are actually a set.  The UP caboose you can see is the other end of the train headed by the Gas Turbine.  Two tracks run behind ‘Hell’s Glen’ connecting the coal mine and power station.  That way loaded coal trains can leave the coal mine and run into the power station, and vise-versa for empty trains.  Loaded coal runs West to East and empties East to West. This system can support trains up to 7′ long.  The level crossing outside the power station has automatic crossing barriers which drop as a train approaches. A very nice touch is that the plant chimney also smokes.

Next, the line runs round a corner and splits into twin tracks at ‘West Fork’.  This module is the opposite of ‘East Fork’ and can also be used as a yard entrance.  This is also the start of the first passing place.

‘Dilithium Propellants’ is the first of the twin-track modules and features what looks like an oil refinery.  But as any Star Trek fan will tell you, Dilithium crystals power starships!

After ‘Dilithium Propellants’ comes ‘Cascade Falls’ which has some large rock formations worn down over centuries by the water tumbling over the falls.  This module is also twin tracked and both lines cross the river on steel bridges.  We always try to pass on the right as this Burlington Northern GP38-2 is doing. These modules were built by Marten and donated to the club when he moved away.

The line now curves again passing through “Twin Rocks’ built by Ted & Chris.  As the name implies it’s also a twin-track module.

The twin-tracks continue through ‘High Plains’ built by Ted.

Ending the first passing place is ‘Desert Fork’ which is another two-into-one module.

‘Desert Fork’ can also be used as a yard entrance and has the lights on the sides.

The single track now continues through a module simply called ‘Trees’ built by Bob.  This type of module we call mileage boards as they are just that, designed to add distance.

After running through all that open country, the line again enters a busy area and first up is ‘Allied Rail’ built by Chris.  This module features a wagon and locomotive repair facility with the mainline passing in front.

The line then curves through the town of ‘Forton’ also built by Chris.

Another industrial area follows ‘Forton’ called ‘Westen Yard’ build by Ted.  This twin module, like ‘Bob’s Pickle’ has many industries and can be used as a stand-alone switching layout.

The yard can also be operated as a switching puzzle. Trains arrive with freight cars in a random order, but identified with a color, as shown below.  The color indicates which industry the cars need to be spotted at.  Any cars already spotted at industries are removed and replaced with the new ones.  The old cars leave with the next outbound train.  Once spotting is complete a new train arrives and the puzzle starts again.

The yard has its own 0-8-0 switcher or ‘Yard Goat’.

Under the buildings at the back are hidden sidings to exchange trains for the puzzle if they are not being exchanged with the mainline.

Leaving ‘Western Yard’ the line curves through ‘Ted’s Farm’ not surprisingly built by Ted.  The tail end of the long Southern Pacific Overnight express freight service can be seen leaving the module.

This Great Northern freight train rounds the corner passing the farm.

After the farm comes ‘Solent Summit Station, which is a triple module, the second passing place and the middle of the layout at two and a half miles.  There are four lines; starting nearest to the station building is the station track, then the mainline, followed by a passing line and goods holding track with head shunts.  We can pass trains up to 9’ here, one can be longer if it’s not stopping.

The station building is actually a model of the “Harvey House” at Seligman in Arizona.  The Harvey Houses were a chain of hotel-restaurants that provided services to railroad passengers and served as station facilities. The Harvey House at Seligman was demolished in 2008, just before the ‘Solent Summit’ layout was started.

As this is the center of the layout there are frequent trains passing by and the SP overnight is headed by a massive AC12 Cab Forward, built between 1943 and 1944, and was the pinnacle of the SP steam power.

In comparison a vintage SP 2-6-0 from the turn of the century heads by on a scenic tour.

The line out of the west end of ‘Solent Summit Station’ can be either single or double track, which extends the possible passing length, but in this set up its single leading into ‘Jon’s Cut’.  The module was originally built by Jon who is sadly no longer with us.  In recent years it has been refreshed by Morgan to add the caravans and campsite.  As the name suggests the line passes through a cutting with rock walls on both sides.

Leaving the cutting, the line enters ‘Sunkist’ which is a double module built by Ted.  One end of the module has a small-town scene with a road crossing and there’s a small station depot in the middle.  Ted says there are ninety-nine orange trees on the module, and he made each one of them.

‘Sunkist’ is an orange plant complete with an ice house and ice loading platforms for filling refrigerator cars.

The ice platforms can load six refrigerator cars at a time with ice. You can tell if a car is a basic box car or ‘reefer’ car as the reefers have hatches at both ends to load ice.  Each car has an ice compartment at each end to refrigerate the center section.  Depending on the distance the oranges will travel the railroad may have more ice houses and loading platforms along the route to top up the reefers.

Leaving the orange fields, the line rounds a corner and crosses an abandoned narrow-gauge line at ‘Trestle Curve’, also built by Ted.

‘New Mills’ is the next module and is built by me.  It features a small passing place at a depot serving a factory complex.  Due to a large number of parcel deliveries and local passenger trains stopping in both directions, the whole depot area has been boarded out.

The line then passes through ‘Flat Rock’ built by Ted.  The large stone is protected as it’s believed to be spiritual, consequently, the line is curved around it.

The last built-up area in this section is ‘Water Street’ which is also a double module built by Chris.

‘Water Street’ has many industries and its own yard, arrival and departure tracks as well as its own sidings allowing for lots of switching.  Some of the industries have covered unloading areas with in the buildings.  This is another area where trains are exchanged with trains from the yards.

The through line runs at the front of the modules as seen by this Maersk Double stack train.

The line curves 90 degrees as it leaves the modules and enters the first of the incline or gradient modules ‘Pope Grade’ which was built by Kerry.  The mainline passes through a large cut as it climbs uphill, from right to left, at 2.5%.  The actual line raises 1 1/4″ over the 5′ module.

The track levels out and passes through ‘Oil’ which is a one-foot long module with a working oil well, or nodding donkey, pumping oil which was built by Bob.

Then the line enters my latest module ‘Tehachapi’.

Not only is this the last passing place, capable of passing trains 17′ long, it also drops the mainline by 2 1/2″.  Any train longer than 13′ will pass over, or under, itself as it traverses the loop.

The blur running down the hill (Not one of Paul’s photos) is the C-855 consist with a long UP box train passing the SP Overnight running uphill.

My previous post, which can be found here, has a lot more photos of the loop.

Leaving the loop, on the lower level, the mainline passes through ‘Plains’ built by Bob, which is another mileage board.

The mainline then curves again through the road crossing at ‘Majestic’ built by Ted.

‘Majestic’ has a hardware store and John Deere tractor dealership.  A Streamlined SP 4-6-4 coasts by with the Hustler.

This has been one of my favorite spots for capturing videos.  Below are the set of C-855s passing by. (Filmed prior to Warley 2019.)

And a Nickle Plate Railroad Berkshire, (Also filmed before the Warley exhibition.)

Leaving ‘Majestic’ the line hits the second incline or gradient module ‘Alver Grade’ built by Kerry.  This also climbs uphill, from right to left, at 2.5% and raises the line1 1/4″ to return it to the standard level.  The scenery is more hilly than rocky as a Norfolk & Western J1 winds its way through the trees.

Now back on the level, the line passes through ‘Sawmill’ built by Chris.  Although it’s a single module it’s the longest we have at six feet.  There’s a logging spur running out the back and it has several sidings to allow it to be a stand-alone switching area if required.

The mill pool is to the left of the module for washing the logs before they’re conveyed into the mill for cutting.  Lumber products are loaded onto the freight cars and the sawdust is either burnt in the pyramid burner or loaded into high sided gondola cars for export.

The line then passes my last module ‘Warsash Wye’ which is a scratch-built timber trestle spanning the Warsash River.

The trestle is loosely based on the ‘Keddie Wye’ trestle in California in that it splits with a line running out the back of the module. There’s a lot more on how I built this module in the How To section of this website.

After the passing the trestle, trains round the final curve on ‘Watson’s Siding’ built by Ted.  The turnout is non-functioning as the siding and buildings are abandoned.

Next comes the ‘Hobo Camp’ built by Bob.  This is another one-foot module with a group of hobos camping in an old caboose.

And the last scenic module is ‘Road Bridge’ which is another two-into-one board with the mainline passing under a road.  A family has stopped on the bridge to do some train spotting, and it looks like they’re in luck as the C-855s are just getting ready to leave the yard.  You can see a green light on the side of the module which means the turnout is set against the C-855s, for entry into the yard.

The twin lines then enter ‘West Yard’ which is a mirror of ‘East yard’.  And that completes five miles of track.

As well as all the modules in the 5-mile setup, we also have an inner curved module with double-track called ‘Waltons Curve’ built by Chris and a single-track outer curved module called ‘Highway 61’ built by Ted, ‘Highway 61’ was named for the crossroads with Highway 49 where Robert Johnson sold his soul to the devil, and also Bob Dylan’s ‘Highway 61 Revisited’.  We were unable to fit these into this layout configuration this time but I’m sure they’ll get an outing soon.  Also to be completed are two small curves, one inner and one outer, with a 45° angle.  These are single-track and will give us more flexibility with the layout shape as all the other curves are 90°.

Seeing the modules individually is great but it’s much better to see them all together so here is Southern Pacific GS4 number 4449, pulling the Morning Daylight, traversing the full five miles from ‘East Yard’ to ‘West Yard’.

Paul Begg who took all the great photos also took lots of videos, and here is his compilation.  Now you know the different modules it should help you understand where the different bits were filmed.

‘Solent Summit’ also features for the first 12 minutes on the video below by DCC125.

We always enjoy running ‘Solent Summit’, no matter what size, so if you want to book it for your exhibition send me a message via the contact page.  We can do almost any combination of modules and the layout can be small or large with anything inbetween.

It was my first time both as an exhibitor and as a visitor, and the enormous size of the show and the crowds it brings in meant I didn’t get to see  very much of the rest of the show, but I hope to in the future and when I do I will share that with you.

Going Uphill – Part 4

As promised this week I have some photos of my new Tehachapi Loop modules for our club layout ‘Solent Summit’.  As with all model railways, it’s not finished, but it runs and it’s just about ready for the exhibition coming up this weekend.

The main section is the loop itself, built on two 5′ by 2′ modular boards, which takes the line up by 2 and a half inches.  You can see the basic boards in an earlier post here.

Starting at the top and right-hand end, the line enters the module, and splits into two lines to form a passing place.  The signal is a Showcase Miniatures kit and does work, just not yet.  Also, the track joint to the next board is offset because the modules are not currently joined together and I didn’t spot that when taking the photo!

There are also two single signals for trains departing the loop.

The twin lines then run around the module and the descent starts just after they cross the tunnel.

The real loop is a lot larger and has some country roads and tracks leading into the center, but as this is compressed to make it modular, I’ve compromised with a path leading up to the cross on the hill.

The cross, at the real Tehachapi Loop, is a memorial to the men who died working the landscape to build the railroad.

The lines run around the hill through a rock cutting, which also helps disguise the module joints.

The lines continue to descend as they run around the back of the module.

In the view below you can see the lines drop from one side to the other.  The gradient is a steady 2.25% on the inner line and 2.1% on the outer.

Just before the lines converge into one, there are two more signals for the exiting trains, but as the lines are now in a cutting and on a bend, these signals are mounted on a gantry so they can be seen by the locomotive engineers from a distance.

The gantry is 3D printed; it’s a model by fellow Shapeways designer Ngineer and can be found here.

The signal heads are angled towards the back of the loop.

The shot below shows how the gantry signals are visible from around the bend.

The line then stops descending and enters the tunnel. From here the line remains flat as it leaves the module.

On the real Tehachapi Loop, the signal for the passing line is on the same side of the tunnel as the gantry, and the locomotive engineers can see it through the tunnel.  But as I’ve compressed the loop, and curved the line through the tunnel, I decided to put the signal on the other side. Anybody watching the layout will be able to see it once I have the signals working.

So there we have a version of the Tehachapi Loop on a modular N Scale layout.

I must admit as much as I like the module I’m not as happy with it as I had hoped for two reasons:

Firstly, I feel I’ve rushed it and I think the ballasting, rock work and scenery reflect this.  But the great thing about scenery, it can be built upon to refine and improve the level of detail. So once the next show is over I can take a bit of time to work on this.

Secondly is the hill in the middle.  The slope of the land formation from the top of the hill to the cutting by the gantry signal was supposed to be more gradual, but I realized I had no more room between modules when they were packed together for transport. One sits upside down on top of the other and the land at the center of the loop almost touches.  So the hill is designed to lift off which causes, I think, an unsightly joint.   But I think I can conceal this with some more careful scenery work to disguise the joint.  Again, the great thing about model railway scenery is it’s never final and can always be changed. I look forward to getting some inspiration and maybe some advice on how to solve this problem at the show next weekend.

But with these two points said, it runs well and I think the trains look fantastic on it.  And once the signals are all working I’ll be very happy.

It’s now only four days until these are set up with thirty-five other modules, not including the non-scenic yards, to form the ‘Solent Summit Railroad’ at the Warley National 2019 Exhibition.  If you’re coming this weekend I will see you there and if you can’t make it I will get lots of photos and videos of the layout to share with you, including a full walk-around video as I did at the NMRA (BR) Annual Convention in 2015 below, which was only 21 modules.

As it’s such a big layout and we have to pack up and drive back on Sunday night I don’t think I’ll have a post next Monday, but it will give me more time to write a  more in-depth post for the week after.

Going Uphill – Part 3

Over the last few months I’ve been busy working on customer layouts as well as getting my own layout ready for the Warley National 2019 Exhibition, which is in less than two weeks.  So I haven’t had a lot of time to work on the 3D printed projects, but that will pick up after the show.

You may recall, back in March, the Tehacipi Loop modules were fully working but rather bare.

Well, about a month or so ago it looked like this.  I admit I was starting to panic!

The base construction is a mixture of cardboard and blue foam offcuts packed with newspaper.

The newspaper worked very well in giving an uneven natural shape for the plaster cloth to follow but the downside is it absorbs all the moisture from the cloth, and in a cold workshop, stays wet.

I had to place the only available heater, an oil radiator, under the modules to help the plaster cloth to set.  I also found that using hot water to dip the plaster cloth into also helped it set quicker.  Well, it seemed to and working in the cold, my hands appreciated it!

Once the cloth had hardened sufficiently, which took a day or so, I separated the two modules and pulled out the newspaper, which was still damp.  The cloth then dried completely.

You can also see from the images above I’ve sprayed the track with a grimy color.  As I passed the spray can over the track I followed round with a cloth and wiped the tops of the rails.  The rails will need a really good clean once all the scenery is done but this helps a lot.

The next step was to add some ground color.  This is important as without it the white of the cloth will always find ways to show through. Just over a week ago the loop module looked like this.

I use either a green or brown undercoat which is just a cheap acrylic paint thinned with water.

Once dried the track was ballasted; you can see my pots of ballast ready to go on the corner of the module.  The rock outcrops have also been positioned, and colored, in the same way I did the trestle module, which you can read about here.

Over the last weekend this module, and the incline boards which go with it, have been totally transformed and now have all their scenery finished.  But I don’t have photos yet, you will have to wait until next Monday for that, as they were still drying when I left them.

The Warley National 2019 Exhibition is on the 22nd and 23rd of November 2019 at the NEC in Birmingham, UK.  You can read more about the show here.  We’ll be at stand number B53, almost in the middle of the hall! Along with my loop there’ll be 6 other new modules added to our layout, so plenty of new works to see.

And if you think the exhibition doesn’t look big, remember that our layout at stall B53 is 65′ by 26′.

Next week I’ll bring you some photos of the modules in their finished state. If you’re coming to Warley you’ll be able to see them in action, but I’ll endeavor to get some good video of trains tackling the loop to post here as well.

Derailments Aren’t Always Easy To Fix!

It’s been a busy two weeks since my last post; I needed to focus my time organizing my club’s annual exhibition, which was another great success as we continue to build on the event year after year, and I’ve been doing some traveling.  This week’s post will be about a train from another country, not that I was there, but I found it interesting.

Every now and again we, as model railroaders, have trains fall off the track, and if you’re unlucky they can end up somewhere that’s hard to reach.  This also happens in the real railways but it takes considerably more effort to pick the trains up.  Normally when there’s a derailment, which can’t be corrected with a re-railer, the rail cranes are called out to do the heavy lifting.  If the train is too far from the tracks a road crane is usually called in.  But sometimes the accident happens where there simply are no roads.  This happened in Scotland on the 28th June 2012 when a CBRf freight train of twenty-four PCA tank wagons hauled by a Class 66, number 66734, hit a landslide on the line from Corrour to Tulloch, along the shore of Loch Treig.

Fortunately nobody was hurt, but the locomotive slid down the bank towards Loch Treig and came to a rest a good distance from the line. The job of sorting out the mess was given to QTS who removed the crashed PCA tank wagons and repaired the line in just 12 days without any cranes.  They captured the whole event on this time-lapse video.

But the locomotive, weighing 130 tonnes (286600 Pounds), was simply too big and heavy for even rail cranes to safely reach and the nearest road was 4 miles away.

So the locomotive was covered up to protect it from the Scottish weather until August 2013 when the job of removing it begain.  The locomotive was declared an insurance write-off and QTS again took on the challenging job of breaking the locomotive up and removing it piece by piece. It took 70 days and again QTS captured the whole event on a time-lapse video.

All in all, this was an amazing achievement and 85% of the parts from 66734 were reused on other locomotives, but sadly this locomotive is no more.

So next time we have a train fall off at the back of the layout just remember how hard it could have been!

3D Printed Gears

If you’ve been following my posts over the last few years you’ll know that I’ve produced several 3D printed gears for a variety of scales.  These have been available in my Shapeways shop and through my individual posts about the gears, but I realized I didn’t have a section on this site for them.  So that’s what this post is about.

The new page, which can be found here, or by using the drop-down menu above, has all the gears currently available.  There are several more in the testing phase, which will be added when ready, as well as several that are waiting to be done; often when I see a damaged locomotive going cheap I pick it up with the intention of making a new part to repair it.

So far the finished replacement gears and axles are for:

N Scale

Bachmann- 4-8-4 Northern (3rd Generation)

Bachmann 2-8-0 & 2-8-2 (1st Generation)

N Gauge

Minitrix 9F

OO Gauge

Bachmann/Mainline 0-6-0 J72

Bachmann/Mainline 4-6-0 Hall

HO Scale

Bachmann 4-8-4

Gützold v60/br106

O Scale

Rivarossi O Scale F9

G Scale

USA Trains 0-4-0 20-Ton

I’m also doing some experimenting with different materials for the gears; you can find the first post about that here.  For very small gears I’ve yet to find a better material than the Fine Detail, although for the larger gears the material is a little brittle and prone to breakage, so I’m hoping to find a suitable material for those.

I’ll be taking a break and not posting next Monday as this coming weekend is the Poole & District Model Railway Society’s Annual Exhibition. I’m the Exhibition Manager, and as fun and rewarding as organizing an event of this scale is, I’ll be needing a rest on Monday! So I’ll be back in two weeks.
