MDOT NPCU #7100
Maryland Department Of Transportation NPCU (Non-Powered Control Unit) #7100 sits for the weekend on a stub track at the former B&O roundhouse in Brunswick Yard on September 3, 1990. The 7100 was manufactured by EMD in February 1951 for the B&O as F7 #293A-a phase 1 F7 to be precise. It was renumbered 4553 during 1957 when all remaining B&O steam locomotives were renumbered from a 4 digit series to a three digit series to make room for the expanding diesel electric fleet.
