(Lego) railroad picture of the day
We got Russell a lego Hobby Train kit for Saturnalia this year, and he wanted me to build something while he and Silas were playing with it. Whatever plans I might have had of doing something elaborate vanished abruptly when they tore into the kit like small tornados, and all I was able to do was to build this model of a vaguely Swiss or Costa Rican electric locomotive (but third-rail instead of overhead wire, because it’s basically impossible to build a minifig scale pantograph that doesn’t look ridiculous.)
The whole lego railroad system is somewhat ridiculous; the flanges are too deep and the stock track is curved like a particularly erratic streetcar system. But the gauge is only a little wider than the standard hobby O Scale(ish) gauge, so it might be possible to fabricate modified wheelsets that are O Gauge (anywhere from meter gauge to standard gauge, depending on how tall you think a minifig is.)
