The smog in Harbin was very localised and we found clear bright sunshine at Wanggang, only 13 km to the south but at considerably higher altitude. QJ 2450 and QJ 2428 were working hard on a southbound coal train approaching Wanggang station on 27 December 1984. The pilot loco was removed there and returned to Harbin. Since the photo was taken, this area has been transformed. The line is now electrified and a flying junction carries the Harbin relief line off to the east.
