One of the locomotives at the Pennsylvania Trolley Museum is Penn Transformer 44-Ton 1311, built by H.K. Porter, Inc. in 1942. (Washington, Pennsylvania – September 25, 2009)

A unique mix of old equipment belonging to the PA Trolley Museum rests on a spur next to the P&OC's line to Arden.

While two P&OC trains were busy working in Arden, I grabbed a shot of this vintage Porter locomotive. Foreground track is the P&OC.
