I've shipped a few rail vehicles, these things are expensive as fuck to ship around. Even lighter railed vehicles that can go on special trailers with rails embedded in the bed cost like $10,000-20,000 just to move across a few states. Shipping cross-country can be $$$$
Then of course storing the fucking thing requires a large building, preferably climate/temp controlled, and locked to avoid vandals. And if possible an automated fire suppression system.
