On my model railroad, to get to my coal mine, the train has to pull into the yard, then back up onto one track, pull forward, and then back up to the mine. I have thought that this isn't quite right, until the day I drove through Zanesville, and there I watched the same scene unfold before my eyes!
The Ohio Central was moving a coal drag up from southern Ohio to a power plant up north of the town. With engines on both end, the train came into town, backed up, crossed a bridge, and then pulled forward to leave town. Here are some photos of the train as it moved through Zanesville.
