A former Southern Pacific GP40-2 now working for the Indiana Harbor Belt rolled an interchange move into UP's Proviso yard in 2003. It would be rebuilt as IHB 4019.
On the other track was a former Chicago and North Western GP15-1 and the "Green Goat", RPRX 2001.
The Green Goat was built from Southern Pacific GP9 2890 and classified as a GGS2000D. Who knows what happened to it.
