I came across a link to this page, which shows an abandoned electric steeplecab near Locust Gap, PA:

I believe there's a bandwith limit on the website, so if you get a page loading error, the only thing I can suggest is to try back later. Anyway, it's evidently a three-axle steeplecab used by a nearby mine. It resembles somewhat Corbin steeplecab #E2 at the Connecticut Trolley Museum. Pretty unusual stuff!
