Another pair of SS4Gs were working westbound coal empties near Xiazhuang on 17 March 2007.
Virtually all the trains on the DaQin coal line were hauled by these twin-unit electrics. The SS4G is a 25kV 50Hz machine with thyristor control and has been in production at a number of works since the early 1990s. Each Bo-Bo+Bo-Bo locomotive is rated at 6400kW or 8600HP so these two were worth over 17000HP.
