On May 31, 2015 the PRLX 3806 was assigned to WS-2X to bring 7 hot cars to Sparta Junction, a move which hasn't happened since Decemeber 2014. The SU-100/99 normally handles the freight going to and from Sparta, however due to a derailment in Marathon, NY the 100/99 only operated once this past week. With no road train to deliver the loads, the extra crew operated the first "Sparta Turn" since the job was abolished in 2014.
