IHB GP38-2 #5629 watches on in the Indiana Harbor Belt's Gibson Yard as a RP15BDF #1508 drills autoracks at the west end of the yard just outside of CP Columbia. #1508 is a locomotive rebuild made by Rail Power and utilizes CAT engines. While the otherwise boxy appearance and LED lights on this unit might be a turnoff for some, it was something different on this day and the engines smoked rather nicely when throttled up.
