Progress on the "latest project":
The train is a toy train my brother found at a local thrift shop. I snagged the gondola car, discovered the gondola body would pop off the chassis with a bit of gentle flexing, and have proceeded to build a protected flatcar on top.
I can't really called it "armoured", as it's rail ties and sandbags, but it's better than setting up a machinegun on a bare flatcar! It's currently sporting Red flags, but the flags pop out and I'll do White flags eventually, for the inevitable changes of ownership. It's not based on any single historic prototype - I call it "plausible" rather than "historical". Lots of different railcars found themselves adapted to war in lots of different ways, so a wood-and-sandbag bunker was almost certainly tried somewhere during the RCW!
My brother is repainting the engine, and the whole assembly will star in a game I'm running at Vancouver's Trumpeter Salute wargame show this coming weekend. I'm happy with the front end, but less so with the back end. It looks kind of unfinished now, but I've run out of time. I might yet slice the curved roof off, run sandbags all the way down the side, and leave the whole thing open-topped. We shall see.
In the meantime, it'll be carrying a Bolshie machinegun detachment into battle with the hated Whites at Trumpeter!
