Watching a lot of YouTube vids on trains I’ve picked up some of the lingo they use. I had heard that term before “Slack”. I didn’t realize just how much is involved in getting these things up to speed and how much braking/acceleration affects the whole train,front to back. One of the things I found out is why sometimes you see 3 engines at the front with one or 2 facing backwards. I always thought it was for torque reasons. Lol. It’s so they don’t have to utilize a turntable when the engine returns from the direction it came from. The lead engine usually carries on somewhere else. I’m sure there’s other reasons but that’s one of them I’ve seen on a vid.
