Need information about friction in the bearings and stuff cause that is the only thing it will stop it (unless it derails). In principle, it will roll forever.

Newtons Three Laws will help you with this.
Rule 2: MxA=F
So 50,000x60= 300,000N
Rule 1: Inertia. This is when an object at velocity will want to stay at the same speed e.g. when car crashes people are thrown forward due to inertia.
I have only figured out part of the calcualtion. Use other answers to continue.
Friction also counts.
