Pere Marquette Railroad footage from 1940's

Old 8mm footage of switching operations on the Pere Marquette Railroad circa. 1940's. No sound. Shots of 0-8-0 steam locomotive switchers #241 and #254. Great shot of steam engine #254 being turned on a turntable. Experts tell me that this was shot at Pere Marquette's Ottawa Yard south of Erie, MI. It was a semi hump yard and the yard tower / office was east of the main line and west of the yard. The coaling dock was 300 tons. This yard was later abandoned after the PM / C&O Merger.
