CR 6011 at Horseshoe Curve on October 17, 1976

^{A bit of a puzzle.  This appears to be a set of helpers holding onto a downhill van train, but no caboose.  So, I wonder if this is a Mail train running uphill against traffic, around a stalled merchandise train on track one and other westbound merchandise on two. It was the middle of the day, about the right time for the westbound Mail trains.}
