Maybe this should be in the main section dealing with rolling stock? Anyway, I was watching the movie "Ghosts of Mars" yesterday (OK so sue me, I like crappy movies ) and got to thinking about SF trains generally So, Ghosts of Mars - Trans Marineris 75 Yankee - pretty much a mobile blockhouse running on normal rails Then there was the train in Spacehunter - a tad more fantasy than SF. The maglev train in an episode of Firefly etc I can see a use for SF styled trains in various formats. Bandits raiding a train in a game. A countdown - player characters have to fight their way to the train before it departs etc. Or just a plain standard diorama feature. World Works Games has a subway car type set up in the Mayhem range but beside that I've come up with nothing. Any suggestions?
