I like how the locomotive works, not often for someone who's not a railfan to draw one so well...also, those pipes coming from the boiler, did someone try using it as a stationary source of power once it was immobilized?
Seriously though, this is awesome. What I feel that the story and even the games kinda missed (well, except for the Pitt in FO3) was the whole trashy and junkyard feel. You add it in awesomely, rather than just 'here be garbage and refuse'. It's just... awesome
