This was one of those truly remarkable railfan moments. I was lost, but knew there was a railroad yard in Corbin. I drove up the wrong road7 and happened upon three SDP35's (#'s 4544 and 4546 trailing) running elephant style, departing the yard.

Numbert 4546 was delivered as SAL 1108, built September 1964 (c/n 29347) on EMD Order 7734. The SAL rostered 20 of these locomotives (#'s 1100-1119), designed for dual service. As it turned out, passenger service soon vanished, and these units spent most of their service lives on freight assignments. It appears to have been renumbered as follows: built as SAL 1108, then SCL 609, then SCL 1959, then L&N 7041, then L&N 4546, then SBD 4546, then CSXT 4546.
