Three almost new Seaboard System B36-7s were leading southbound TOFC hotshot No. 175 out of Acca Yard and past West AY interlocking in Richmond, VA on Sept. 28, 1985. The B36-7s were known for their speed and used on Seaboard System's hottest trains. For some reason, on this day, No. 175 was short one unit. Usually it rated four.
