Most of this units OMNITRAX history can be seen through the paint. Can you tell it's a CTRW unit? Originally IC 9115, this GP10 has since served for Missisipi & Gulf, Mid South, Carlton Trail, Okanagan and GWRX Railroads!
After a short stint on the CTRW in 1998, he came back in 2001 bearing Central Kansas Railway (GWRX?) and Okanagan (OVR) banging, far from the lime-green CTRW tademark color, one can see on CTRW 1004 next to him. I believe he's currently the only unit painted in this sheme, a sharp difference to the onslaught of green and zebra CN coloring.
