Walkthrough
Our first objective in Borderlands 2 3:10 to Kaboom is to go to the demolition depository marked on the map and capture the RC train. Hence, we exit the train station, we take a right, and at the end of the road we use the elevator (the smaller one, not the one in the tunnel) to climb to Death Row Refinery.
The Borderlands 2 3:10 to Kaboom mission timer starts when we are near the button and Brick gives us the instructions. We press the button to activate the RC train, and then we quickly turn around and go to the next button to close the small gate so that the train cant go any further. Then we grab the bomb cart.
Now we have to go to the next waypoint to place the cart on the train tracks used by the Sheriffs train. When the cart is placed on the tracks, Brick tells us to go and use the detonator at the marked location. Also, the Sheriff will share a story about Brick, but we ignore it and we run on the stairs to get to the detonator.
Now, we have to wait for the train to come and load the Eridium, and we press the detonator. The explosion allows us to complete Borderlands 2 3:10 to Kaboom, and we have to go back to the bounty board to turn it in (depending on when we visit Lynchwood, Brick may have another mission for us, called Breaking the Bank).
