Crowl, a hamlet of 40, was on the 27-mile PRR Shamokin Valley branch between Sunbury and Mt. Carmel. It was one of the last places to see operating PRR steam. Abundant coal, good water, heavy seasonal loads of slow-moving ore, and a ruling grade of 1.3%, all made this branch the perfect place to assign the last of the 2-10-0's> on the Pennsy.
