Southern Belle on the Southern Railway

One say, as I am crossing the NS Cincinnati-Chattanooga line, I spot something different in Erlanger Yard- the front of a Kansas City Southern unit. Quickly pulling off to try to take a pic of this unit, the train rumbles over the bridge above the US-25, not too far from Erlanger Yard, with two KCS units pulling the train. As the train passes by me, I can classify the lead unit as SD70ACe #4117, and I believe the second unit is SD70ACe #4057. This one of the two shots I took of the train; the first one, for some reason, had a very low exposure and made the picture look very dark. This is the first time I have seen a KCS unit if memory serves me correctly.
