The engine in the photo is CVRR #81, effectively a PRR narrow Belpaire boiler H6 2-8-0.
But just what is that car out in front of it?? I had a passing thought that it might be some sort of clearance car and that the long "white" bar linked to the pointed bit with the ball at the end might swivel out from the side of the car? I can read ....LING C on the side. Poling car? Thoughts?
