  •  Train Brakes (3+ / 0-)

    They operate by air (not hydraulics).  Train air brakeoperation is a little more complicated than I want to go into here, so please see the wikipedia link for a discussion.

    Basically, the brakes go on when the train line air is reduced.  But they are applied because of a reservoir of compressed air on each car.  That air leaks off over time and the brakes come off.  So to park a rail car, or a train, it is necessary to apply hand brakes.   The phrase : "set the brakes on a sufficient number of cars on the train" comes from a regulation and/or a railroad operating rule having to do with leaving a train unattended.  And it will likely be the basis upon which the person responsible for setting the brakes will be judged.

      with the video in a comment above also says that they had people out doing stuff to the train when it was on fire and so the brakeman who "set sufficient brakes" may not have been the last person to touch the train before it began rolling.
