BIG JIM,
Back in the day when NS, was an 'all DC railroad' and AC units were starting to be used by other roads, did you ever have to handle a consist with a run-through power AC unit on point?
Did you just figure it out as you went along?

EMD,
Yes, I guess in a way that I did, although I never thought of it that way. My first experience with AC units were with a set of CSX units and as you say, I figured it out as I went along...just as everyone else had to do. No big deal, there really wasn't any big difference in how they operated.
The one thing that stood out was that the dynamic brake would hold all the way down to almost stopping! That was very impressive! Much more so than any extra tonnage the units were able to haul.
