Description Not sure that this is the best picture I can make of this, but it's the one I had right now.

I've been really bad about posting pictures of my model railroad modules, despite me knowing that some of you area interested in that. Sorry about that! This is the latest I finished (about two months ago). This is all following the T-Trak standard for small modules in N scale using Kato Unitrack tracks.

The key thing I wanted to try here were Kato's slab track pieces. I've also bought a starter set of Viessman overhead line equipment a couple of years ago and never got around to using it, so I wanted to try overhead lines as well. Then there was also my plan to experiment with noise abatement walls built from polystyrene strips and plates. And finally, when I put the plant together, I decided I wanted some tunnels. I've also decided to make a symmetric module, just for fun, that has the same width in either direction. For what I wanted to show, I don't really need more space. That said, the noise wall does pretty much define what is front and what is rear here.

The tunnel portals are from Faller, and required some extensive paint work to look anything other than horrible. The tunnel itself is formed from black cardboard, painted gray with acrylic paint on the outside. The basic structure is a wooden frame with aluminium mesh stapled onto it, with plaster bandages creating the surface layer. This is the second module where I've used an electrostatic grass applicator, and I think the results are really nice.

For the Kato tracks, the area between the lines looks bad and too much like grey plastic, so I had to choose between painting it (which would mean painting the entire track piece; technically not a bad idea but difficult to keep the rails clean in practice) or covering it with ballast. The latter is easier and still looks good, and you can actually find similar prototypes in the wild, e.g. the slab track "System BΓΆgl".

The overhead lines have no electric function; I use DCC for everything so that would only complicate things. For a line like this you'd normally have concrete poles instead of the green metal ones, but I didn't have concrete poles, only millions of green metal ones, so there you go. The wires are bent up and glued to the tunnel wall where you can't normally see it; there are no plans to create continuous electric sections between modules. To be honest, with this Viessman system, I'm not sure I like the trade-offs it makes; it's a lot of work to install it but it doesn't look all that awesome. I suppose it may be a good choice if you want to actually use it with power, but I figure once my Viessman supply runs out (which will likely be years in the future), I'll look at the more detailed, deliberately non-functional systems e.g. from Kato themselves, Dapol or (arguably the nicest from what I've seen) Mafen.

The train is a Thalys PBKA by Kato; I think I've posted detail pictures of this on here before (years ago).

The module must show a french high speed line. Why? Because of the pantograph! All high speed lines in Europe uses AC, mostly 25KV 50Hz, but some are are powered by 15KV 16.6 Hz. In France also exists some older lines with DC 1500 V. Which means, that all TGV without any exceptions are at least bi-mode vehicules. The Thalys trains are from the technically point variations of the french TGV, but adapted to run under the dutch DC 3000V lines (Version PBA) and some are even capable to handle AC 15KV (Version PBKA).


There's an easy way to find out if a TGV is running on a AC or DC line. A TGV has a power car at each end (in fact streamlined locomotives with just one cabin) and eight carriages between. You just have to watch to the pantos. When running on DC, the pantographs of both power cars are lowered, but when running on AC just the pantograph at the powercar at the end of the train. The front locomotive get's it power by a high voltage cable on the roof of the carriages.


As you can see on the picture, the pantograph is risen. Because the module shows a high speed track, it's AC. Which means, this is the end of the train which runs from left to right. So it's running on the left track, which is normal in France and Belgium, but not in Netherlande or Germany. But the belgian high speed lines are in quite flat terrain, so only France left.


Well, maybe it's in Germany and the train is using exceptional the left track, which is no problem following the signalization system.

This is awesome, I love the appearence of Thalys trains!
