Conrail placed additional orders for SD80MACs, however due to the pending takeover by Norfolk Southern and CSX the order was changed. CSX opted out of the SD80MAC order in favor of SD70MAC's built to CSX specifications. The 4,000hp locomotives were numbered 4130 - 4144, assembled and painted at the Juniata Locomotive Shop between March and May 1998 in the white face paint scheme as found on the SD80MAC's.
