For awhile the UP had the 3 Rio Grande GP60's running together on the Denver to Pueblo trains over the Joint Line. Here the trio make their way south towards Pueblo somewhere north of Palmer Lake. By the late 90's one of the GP60's had received Amour Yellow, and one had received an ugly scotch lighting strips. Only 1 GP 60 still looked original as it could get.
The ex-3154 is currently the UP 1168, freshly renumbered, the ex-3155 is currently UP 1081, and the ex-3156 is currently the UP 1902, all is UP yellow now.
