Watch massive machines lift and dump contents of an entire train car

Rotary car dumpers (aka wagon tipplers) are used for quickly emptying coal and ore from hopper cars. Traditionally, hopper cars emptied from the bottom.

Enthusiast Chester Hill praises Pittsburgh-based Heyl & Patterson, who build these behemoths:

This is the Single Rail Car Dumper that has been in operation over 15 years. Drummond Coal purchased Heyl & Patterson Equipment, and are now building the the first Quad Car Coal Dumper at the Drummond Port in Santa Marta, Colombia.

Here's a longer clip from a different type that shows the entire process, not just the dumping:
