Passenger trains transport workers from Baiyin Xinzhan, in the city near Baiyin Shi CNR station, to the smelter at Sanyelian and the copper mine at Shenbutong. The afternoon train from Baiyin to Shenbutong was difficult to photograph in the gorge north of Sanyelian in November as the track was in shadow most of the way. SY 0965 was photographed as it passed one of the few spots where the line was still in sun on the afternoon of 25 November 2005.
