Guys It was just announced that Atlas is going to be doing Seaboard Air Line GP40's as well as RF&P GP40's in the next run. This run is due out in October. They will feature 2 numbered units and one un-numbered unit for each road...Man, this is GREAT news indeed. Well, looks like some of that SAL brass will be doing up for sale now. OH, these GP40's are in HO scale. You O scale guys have a GP40 coming in SAL paint from Mikes Train House. That will be an awesome unit.
