This photo came labeled as the Annapolis Short Line (ASL) engine 5 at
Cliffords. Both Herb Harwood and I believe that location is incorrect.
For a period around 1900, the ASL followed the B&O's South Baltimore Branch
plus Camden Cutoff to reach into Baltimore city.
One candidate location is near Bush Street, looking southwest. In the
distance there appears to be a structure on the left, about where Carroll
Tower had been. That could be a bridge over the tracks at distant
center, which might correspond to Curtis Bay Junction where the Curtis
Bay Branch crosses over the Camden Cutoff. If you believe
a different location is a better fit, please let me know.
