This photo had to have been taken around 1964, as I believe the Air Rights building (visible under construction in the distance) was completed in 1966. S2 9023 was built between 1943-48. I’m not sure of its original three digit number. The B&O Freight Station is visible to the left of the cab and the engine is sitting on the main, just past Bethesda Ave. I stumbled on this photo while looking at the B&O Diesel Roster on North East Rails.
