East Broadtop railroad Rockhill PA has the whole setup, narrow gauge rail, left just like it was when the workers walked off the job back in early 1950's when they shut down. Loosing too much business to the improving highway system and couldn't keep going. Sold to a scrap dealer, but he recognized the historical value and did not scrap it. Many others did get scrapped.
Although some deterioration has taken it out of operating condition, the shop boilers were inoperable, and the preservation club didn't have the money to replace them last I knew. But they did have the shop steam engine functioning on air. They did everything there except build whole locomotives. Did build cars of all kinds, box, coal hopper cars and passenger. Plus rail maintenance and engine repairs.
