Because it has a clockwork mechanism, it needs to be wound up again before the journey can continue. I found a winding tool of sorts.
In order to get my immobile train up there I need to:
Open some locks so a tugboat can pull the train forward.
Fix a mechanical bandstand for three University regents who must have graduated from Three Stooges University.
Recover a mammoth doll from a paleontologist who creates wine as a side hobby.
It may not sound like much to do but the path to accomplishing anything is very long.
