hmm... to me it looks like his train was spawned off the rails. I've never seen any train to actually leave the rails in TD2.
Oh wait... Was the scenery offline when you arrived or did the dispatcher disconnect before setting your route? All the junctions are supposed to be set in default position if you load offline scenery without AI dispatcher. So you probably ended up on an end track somehow. I can see a junction to your right on that screenshot and there are no spawns near those meaning you've been travelling on the scenery for a while.
