I'd been meaning to dig into coutumariee's collection on MilitaryTrainz for some time now...
Railguns
Armored Trains
All coutumariee's assets appear to be static 'buildings' and not railcars.
Facing all this armored might N3V was only able to field an old French tank poorly camouflaged as a giant rubber duck and Tony in a chicken suit. (also by coutumariee)
