Up To Hard Shell On The Rolling Bridge Module

The Kato/Woodland Scenics T-TRAK module kit includes materials for a whole scenic system, including what they call Shaper Sheet, with Woodland Scenics plaster to finish it off. It was interesting to try this method. The photo below shows recesses cut in the foam front and back to accommodate the channel, with Shaper Sheet fitted and cut for the basic scenic contours.

Then I used Sculptamold to fill in all the gaps so the plaster wouldn't leak through when I applied it.

Finally I mixed the plaster according to the kit instructions and applied it to the Shaper Sheet and Sculptamold. I used masking tape around the track and bridge while I did this.

The result is classic hard shell. The next steps will be to sand the plaster smooth and clean things up a little more, and then add color to the surface.

Scenery Work On The "Rolling Bridge" Module

The Woodland Scenics T-TRAK module kit includes a section of their Shaper Sheet for the scenery. This is just enough to cover the scenic area of the module. I studied the instructions and decided I could use it as intended to create a stream bed under the bridge into which I can eventually add scenic water. I cut out approximately sized pieces with scissors, used a ruler to help bend the sheet to shape the channel, tested it against the module, and cut the pieeces to final size.

I attached the pieces to the sides of the module with silicone caulk held down with the foam pins provided with the module kit.

Then I connected the module as I'd brought it so far to a temporary T-TRAK compatible layout with power so I could test things out.

I got a chepo foam cutter off eBay to cut the shape of the channel into the front and back of the module to match the shape of the channel in the Shaper Sheet.

I'll fill in the various gaps with Sculptamold, sand things smooth, and add a finishing layer of the Shaper Sheet plaster included with the module kit.

The Woodland Scenics T-TRAK module kit is more expensive than ordinary wood module kits from other sources, but it includes track and scenery material that aren't in those kits, and it's the easiest option for adding something like a stream channel below track level.

More Progress On The "Rolling Bridge"

As I said in my last post, I intend to mount my AHM drawbridge in a single-wide T-TRAK module that's single track but otherwise follows T-TRAK architecture. As it happens, the bridge floor and track that come with the kit, when spliced onto a section of 2-1/2 inch long Unitrack at each end, will just about exactly fit onto a standard single-wide T-TRAK module with roughly 1 mm left over on either end. I wound up shortening one of the Unitrack sections by about 1/16 inch with a cutting disk in a Dremel. I substituted Atlas N rail joiners for the Kato Unijoiners on the ends facing the bridge and soldered everything together.

Then I attached the track assembly to the bridge with CA glue.

And then I mounted that assembly to the kit base, which I had earlier cut down in anticipation of mounting it to a T-TRAK module.

I decided the Kato-Woodland Scenics T-TRAK module kit was the best candidate, since fitting the bridge assembly to the module would be a trial and error process, and foam would be the easiest material to work with. I wound up having to cut more material off the AHM kit base to get everything to fit, but it all worked out in the end. The track is fastened to the foam base witha mix of silicone caulk and the foam adhesive supplied with the module kit.

I still need to pack scrap material around the bridge base to straighten everything out and keep it rigid.

The AHM-Pola "Rolling Bridge"

I've been aware for some time that AHM issued a kit for a so-called "rolling bridge" in both HO and N, and since I've always liked drawbridges, I've always had it at the back of my mind to find one. However, I never ran into any at a swap meet, and partly because I wasn't aware of the exact name of the product, I could never locate one on eBay. It was only very recently that I discovered it was issued under the name "rolling bridge", and voila, I saw two on eBay at a moderate price.

I got the N version, because I figured I could adapt it to a T-TRAK style micro layout or diorama, whereas I don't have a good place to put the HO version on my main layout. Here's a copy of the art on the box:

The model version as produced by Pola, AHM, and Tyco has a brick machinery house and an additional short span that aren't on the prototype, which is located at Wingo, CA on the Northwestern Pacific. This is a line that I occasionally railfan, and I've always wanted to get photos of the prototype, but the area is hard to get to, and even harder in recent years, since the land now seems to be fenced off. However, this is on the NWP's connection to the California Northern and UP, and the bridge is still in use, although it's currently opened very seldom if at all.

Here's a photo of the prototype:

Here's the kit as I assembled it. Especially painted silver like the prototype, the detail really comes out nicely.

The length of the track on the bridge as I assembed it without the third span at the other side of the draw is 7-1/4 inches, which makes it a good candidate to install in a single-wide 12.20 inch T-TRAK module. However, with only one track, it won't meet T-TRAK standards, but I'll use it as a mocro layout component with the 3-2-2 Inglenook I discussed in my last post.

I decided not to make the model operate, as this is more complication than I want to deal with, and the prototype only opens on request with a lot of advance notice anyhow. As far as I can tell, the prototype only has manual operation.

More Work With The N Micro

I'm feeling my way along with how to operate my 3-2-2 N scale Inglenook. I did a fair amount of N scale 30 and 40 years ago, but never much switching. I'm starting to think N scale cars need more weight for this, plus near-perfect trackwork. Building a layout from recycled track materials has its challenges, but two steps forward, one step back!

I've been able to unpack several N freight cars from long-term storage, refurbish them where needed, and put them into operation.

ATSF 48240 is a Micro Trains car from about 1980. There was no internet source of freight car photos at the time, but looking up photos of cars like this now shows Micro Trains got it pretty much right. I believe I added the COTS and U1 wheel stencils when the car was new.

N&W 12987 is actually a car of 1980 vintage, but I got it recently off eBay at a good price. I added Micro Trains roller bearing trucks with couplers.

When Conrail was new in 1976, Walthers brought out decals for some of the first cars with Conrail paint patches. This is a Micro Trains car that I painted Penn Central green, masked off areas to represent clean new paint patches, weathered the rest of the car, and then applied the Walthers decal patch lettering over the clean areas.

Southern 78197 is another Atlas car that I renumbered by covering the last three numbers on the factory paint with boxcar red patches, then added new numbers from a Micro Scale N Southern freight car set. The numbers matched pretty well. I also added the COTS stencils. These are the 1970s style consistent with the prototypes I saw at the time.

Making A Micro Compatible With T-TRAK

I've had an N scale Inglenook micro layout in progress for quite a while. Recently I put it up on top of a bookshelf to work on it next to a T-TRAK module.

With it next to a T-TRAK module, I inevitably began to think about how things might be if I could connect the two together. I had already made a start by linking them to a Digitrax DCS-52 command station on the same DCC bus. Not only that, but all my pieces of layout have a single accessory address standard, so if they're linked together, they're contollable as a single layout no matter what.

The first question was that the Inglenook would need to be able to interface with the Kato Unitrack/Unijoiners on the T-TRAK modules. I did this by carving a rebate in the baseboard to let me add a short section of Unitrack to the tail track of the Inglenook at the same rail height as the rest of the flex track on it.

The next step was to shim up the Inglenook so it would be at the same height as T-TRAK modules. I also covered the gap in the baseboard around the short section of Unitrack with Sculptamold.

With the height established, it was just a press fit to connect them.

I had already designed both the Inglenook and my T-TRAK modules to be electrically compatible over a single DCC bus, so running a train from one to the other is no problem:

I'll expand the Inglenook as opportunity presents itself with T-TRAK compatibility in mind.

More N Items

PRR 9175 is a Broadway Limited N scale NW2. The was my first railroad, since I was born in Philadelphia, and one of my earliest memories was a train trip with my mother, during which she woke me up, stood me up to the coach window, and told me we were going around the Horseshoe Curve. Apparently the conductor had just announced this. I have a clear memory of a J1 on an adjoining track. This loco takes me back to my earliest railfanning days.

I got the NW2 to operate on a 3-2-2 Inglenook, shown below. I'm debugging the track.

DOWX 18357 is another Eastern Seaboard Models N tank car from the early 1990s, 30 years later re-equipped with Micro Trains trucks and couplers.

PRR 83247 is an Atlas N car from the 1970s, found on eBay at an OK price. I needed to increase my freight car fleet with more PRR cars from the 1950s. I swapped out the trucks and painted the black plastic roofwalk.
