Are you sure you sold them? When the buyback shop was removed from the game, it became impossible to sell something that is needed for a future contract and can't be bought in the regular shop. So it should have been impossible for you to sell your Mechanicon steel wagons. And I think I read somewhere that, when the buyback shop was removed, anyone who had sold something that was now unsellable had that item returned to them. Unless there's a bug in the game, you must have those wagons somewhere.
