Looks like #50 is finally stretching it's legs in revenue service on a freight back to Baker teamed with eng. 10 as train #6, 11hours 45 min. Somewhat confusing is that 10 and 50 are also listed in work train service for 10 hours 15 min. Could be 2 crews, one being a night shift, or perhaps on some of the moves doubling or tripling the grades, 10 and 50 were hauling ballast on what would normally have been light moves. My inclination is a second shift as the 1 1/2 hours difference in times would not have been enough for the east bound revenue moves?
