LOL they do look like the train cars from half life 2
They also look like closed car carriers, theres one company I know of called National Steel Car of Canada here in Ontario Cnd, who make rail cars.
Without seeing the interior of these rail cars I'm going with my idea, they are closed car carriers.
Why are they covered? well protection from weather and theft of car parts is why.
Anyway just my opinion
