An eastbound intermodal is getting close to the top of CSX's west slope of the Alleghenies, and will soon make its way down Sand Patch Grade into Cumberland, MD. Only a single unit up front on this train, but another was imbedded about halfway back in the train. That's the former Western Maryland Railway Keystone Viaduct overhead, originally part of that road's Connellsville Extension, and now in use as part of the Great Allegheny Passage trail from Washington, DC to Pittsburgh.
