Showroom, Renewed. CSX K682-12 was tied down by Chapel Avenue in Jersey City, New Jersey on Saturday, January 15, 2022 with CSXT 4571 (SD70AC) leading. This unit was built in 3/2000 as CSXT 771, but is a recent graduate of the CSX Huntington, West Virginia Shops Rebuild Program. This process turns SD70MACs into SD70ACs, with a rebuilt EMD 710 prime mover, new display screens, and more. The paint shows CSX's newest variant with its website under the "X", a decal displays the completion of the Huntington rebuild program as an "SD70AC" and just above another emblem shows the the engine can be used in Distributed Power mode.
