"Rob the train" is an objective in the sidequest The Pretty Good Train Robbery in Borderlands 2
Walkthrough[edit]
After each of the safes is blown open, a large amount of money will go scattering around the train. Some will land on top of or under the train. Grab everything you can.
As you loot, you will hear that a distress signal was dispatched. Loot all the money you can, pull out a corrosive weapon and deal with all the Loaders that come to deal with you.
