I was going to pickup some lunch today and was stopped by funny metra train. At each end was a UP little loco with the lower intake or exhaust like a tunnel motor. I don't remember the road numbers. Is this it? http://www.rr-fallenflags.org/up/up1741h.jpg Thanks, Loco1999
GP15AC or GP15-1, depending in sill (UP has both) Photo linked is a GP15AC, former MP. The GP15-1s came from C&NW and also MP.
