It's 11am on June 8 and Amtrak P052, the "Auto Train", has discharged all its passengers and automobiles after its overnight run from Sanford, FL to the Lorton, VA terminal. By 4pm, the consist will have been cleaned and reloaded for the daily trip south as P053. Note the turntable at the upper end of the yard. It is relatively new, replacing a wye track that was removed due to the widening of adjacent I-95.
