CSX Z601-23 (NS 72Z) (Memphis,TN/BNSF-Kingston,TN/NS) has clear the north-end of the town Bridgeport, AL (M.P. J-122.3 S.E. Bridgeport) and is making its way south for Chattanooga, TN for the NS. On the rear end of the Tennessee Valley Authority 90 car coal bucket is a former BN executive paint scheme "Grinstein green" SD70MAC doing the honor to run as Distributed power units (DPU). This train is slowly heading to the Tennessee Valley Authority Kingston Steam Plant in Kingston, TN one of TVA's Largest and probably fossil plant that is still online. The SD70MAC on the BNSF are out of storage, and being put back into revenue, but are on borrowed time. The BNSF is sending most of their 70MAC off to be rebuilt into the SD70MACe, and getting the new BNSF Heritage III paint scheme, so the "Grinstein green" and the Heritage II scheme are slowly fading away.
