If there is a brake button, it does nothing.
Running into the cargo train happens every time, no matter how good the crew is.
This happens because if the Engineers *don’t* fire the harpoon, the game automatically connects the harpoons during the collision, which then causes the falcon to fall when the train goes down the “elevator shaft.”
This is the sequence that results in getting the first coaxium, which happens even if no one is in the cockpit at all. It’s all on autopilot up until that point.
The second coaxium is the only container that the players can either get, or loose/ not get.
