The same thing happened in Framingham, Mass. last year. A Bay Colony RailRoad locomotive was dragged by B725 (FR-35) from Framingham to Attleboro with a hand-brake applied. 21 miles @ 10MPH with now HBD along the route, it was never noticed until the engine along with the train for Cape Cod, was interchanged with B726 (MI-01).
The result was three to four inch flat spots.
