Momentum Usage.

[FCIN]

I always use momentum, especially with the DCC locomotives. I set the acceleration value to match as closely as possible how the prototype locomotive loads up (GP-40, U28B, C420, etc. load slow - switchers tend to load faster), but the deceleration value lower for quicker stopping if needed. Of course when you're switching at prototype speeds and coupling at less than 4 scale miles per hour it's no problem at all - just a bit frustrating waiting for the big 4 axle to load up and move! But then that's the way it is.
