@BK: I think I'm going to create v1.1 of the straight section, with added details, finer grade ballast, and the rails built-into the cast. I like the idea of a destroyed section using the plastic rails, but having them as part of the track means less work for everyone. And, the track will always line up, so future trains can roll without issue.
Guys at the FLGS suggested adding rail spikes. I've also noticed that the coarse ballast I used is taking a toll on the RTV mold. Every other cast tears a small tiny piece. It's not noticeable once you paint it, but in time, the mold won't have the same details. So... I'll try using fine grade, with some medium sprinkled in for variety.
Here's an alternate painting of the current v1.0 track.
I was lucky to find some O gauge trains at a sidewalk sale for $10 each. Woohoo! Now I have some models I can use as guides for building my own.
The Warmachine players at the FLGS asked that I make some flatbeds wide enough to accommodate warjack bases, which would also be wide enough for some of the larger models in the Malifaux line.
Any other suggestions for trains?
