This images taken on the northwest side of the Furong Bridge shows DF4B-2608 with a southbound passenger train.

Notice that the electric generator van is located behind the locomotive.

On the majority of trains I spotted, these vans were placed on the end of the trains and not the front.

Using my outdated timetable, my best guess for this train is ... K583.
