This is some what of a problem that has been messing with my head since I started the 2010 game again recently. WTF happened to the ELB time train that emmet supposedly used to travel to 1931? Did the developers just forget about it after the delorean came back? Or did the ELB time train have an auto retrieval device of its own autonomously flying it back to 1885? That would be the only logical fate I can think of for his train. Otherwise if he left it parked on the train tracks somewhere, someone would have eventually found it, used it and screwed up the time line in some way.
