Summary

Description
English: Old power board at Paoli interlocking tower on the PRR Main Line. The power board controlled both local catenary circuits as well as the high voltage switchgear for the 132Kv transmission lines and associated transformers. The presence of both 1915 and 1930's era equipment resulted in a rare local control setup. Marked the boundary between the original 1915 suburban electrification and the 1938 Main Line electrification to Harrisburg.
