How The AT Switches Power

Not P40's or P42's but,

is a video of 98 dropping off a Dash 8 at SFA and switching leading diesels. Overall a nice video.

Very nice video...in my day, if the trainmaster saw that kid make the A/C walk all that way to line a switch he would be home for lunch.

Why switch the lead engines?
