But is the train crash part of the “original” timeline or the “changed” one? (Or both? And if both, did it happen the same way in both timelines?) Maybe to re-set history back to the “way things were”, they need to cause the crash, not prevent it (if in fact the train crash had always been a part of the “original” history)!
