About 50 miles west of Harrisburg, PA on the PRR's mainline stood the impressive Denholm Coal Wharf, built in 1906. It spanned the four mainline tracks, plus eight others. It survived into the late 1950s or early 1960s. I stopped by the site in the early 1980s and found only a bridge abutment remaining. Just five miles west of Denholm were the Hawstone Track Pans.
