These are the nearly abandoned shop buildings of the narrow gauge East Broad Top Railroad in central Pennsylvania, at Orbisonia. It's been out of business as a commercial carrier since 1956, yet continued on as steam powered tourist attraction for four decades until recently, but it hasn't run at all for a few years and has fallen on hard times.
It's an intact turn of the century steam railroad and all 37 miles of it still remain from it's coal and gannister hauling days. In fact, these shop buildings still house all the equipment that was used to make or maintain everything that was needed to operate, and all seven steam locomotives and rolling stock are still on site. All in all, it's a Smithsonian grade industrial age artifact that needs recovered and restored, and I hope it gets that chance someday.
