Rio Grande's workaday freight #151 grinds its way west up the 2.4% grade approaching the Kyune Tunnels. The 151 shuttled cars between East Yard in Grand Junction and Roper Yard in South Salt Lake. A nice variety of cars and piggybacks trail a Southern Pacific 'baby boat' GE, a novelty on the D&RGW main before the purchase of the SP in 1989.
