On the weekend of September 24-5, 1983, two excursions were run on the B&O out of Baltimore. The grapevine said that the power was to be the former Clinchfield F-units, freshly painted in Seaboard System colors. The F’s were delayed getting to Baltimore, so they only ran on the Sunday excursion between Baltimore and Martinsburg via the Old Main Line.
The Saturday train, which I also believe ran from Baltimore to Martinsburg, but via the Metropolitan Subdivision, received a pair of Chessie GP40-2’s for power, and we were let down after an early morning drive down I-95. Since the excursion “only” had the Chessie units, we took one shot on Thomas Viaduct, and stuck around Baltimore to shoot other B&O action.
