One more comment- Tiny Sheffield PA was served by 3 railroads- The Tionesta Valley (3ft gage) owned by Central PA Lumber Co, the PRR, and what I call the RGS of the east- the barely running Std gage Sheffield & Tionesta Railroad. Robert Richardson had photos and film of both the TVRR and the S&T. Some are in the CO RR Museum as I saw them myself during a visit last year. When Bob moved back to Bellefonte, PA we had the pleasure of watching some of his films of these lines. Amazing but I do not know what happened to all that footage after his passing.
