NS 1073 is painted as a Penn Central locomotive. Penn Central was formed in 1968 when the bankrupt Pennsylvania RR amd the also bankrupt New York Central were merged. This is actuall a very dark green color, not black. But you have to get real close to see the difference.
Penn Central was the backbone for the multiple mergers into Conrail in 1976.
