"Dump coal into Furnace" is an objective in the quest Get Frosty in How Marcus Saved Mercenary Day DLC
Walkthrough[edit]
Once the Nippers have been dealt with you can easily head over to the platform to the East of the furnace. You will find the controls there. Just hit the marked panel to start moving the crane. It will take some time for it to go over the train's coal car. If you haven't dealt with the Nippers then now is the time. Aside from that you just need to wait for the coal to get into the furnace via the Coal Chute. Now it is a simple matter of getting the furnace going again.
