I have a cold and I'm tired, so I'll post better pictures later, especially ones of the new T-Trak module I recently built. But I did want to show at least this little thing I did with some of the leftover material. Not all of the leftover material, though. I have so much leftover wood strips…
Anyway, this is a very small section of a North American style railroad trestle (I think they're also a thing in Australia?), based on plans by the Great Northern, but then adapted with more bracing because I think that looks better. The height is chosen so that it can be connected to T-Trak modules if you replace the connectors. The track is… I don't actually know. Might be Minitrix? Something I found on my desk.
The wooden structure is all built by hand, out of 2x2 mm balsa wood (main frames), 3x3 mm pine (the sections under the plastic track piece and 1x1 mm linden for the bracings in the longitudinal direction. All cut by hand with a sharp cutter knife (except the 3x3 mm pine, I used a tiny saw for that) and glued together with wood glue.
The locomotive is either Athearn or Atlas, I can never remember which of these is which. I think Atlas. And yes, the rear truck isn't on the rails properly, as I said, I'm sick.
This project was a lot of fun, as was the full T-Trak module (I'll post about that later, hopefully in a couple of days), but also sometimes a bit annoying. I know a couple of places that I could do better, but the main one is the ties. They should be much wider for a bridge like that, but I am not aware of commercially made wide ties. Maybe I'll need 3D printing for that, because I don't think gluing rail profiles to wooden ties is the proper solution. Still, it looks neat as it is. Feel free to ask questions if you have any!
