Train Jacking part 1

So I'm sitting at home with no intention of riding the bus today. Suddenly I hear that there was a train collision on the Blue line out in Forrest Park, IL. A train collision? How did that happen? Well, according to the news report, the train was on the wrong track and hit a parked train and ended up with like 30 to 45 casualties. They speculate that someone had stolen the train. Wait, what?! This brings up serious questions. How do you steal a train? Once stolen where are you going with said train? Once you get there what are you going to do with your ill-gotten train? Are you going to put it on Craigslist? Are you going to sell in on eBay? Will Paypal be able to handle that kind of transaction? What if you get your train and discover that it's not the train you wanted? How do you return it and get your money back? So many questions.
