Pumping up the air!

Thanks for the info guys, and Reinhard, thanks for the link.

Take my industrial shortline, or the LAJ as an example. If we were taking 8 cars at a max of 10 mph for less than a mile, to be switched at some industries, would we connect the brakes and pump everyting up? Or would we rely on the engine brakes?

If you are going out of the yard as a train the breaks have to be fully operational in any case. It is not important if the distance to travel is below one mile.
Ones the industry has been reached and the industry might be huge the engine might switch with a cut over a mile within the industry or a huge yard with breaks from the engine only.
