Conrail 6722 idles at Allentown Hump, MUed to an ex-PC SD40. I assume these units were substitute hump power on this particular day, as an SD38/MT-6 slug combination would have been more common. 6722 features a patch of scorched paint in the area above the prime mover...very common on these particular units.
