Located entirely in Shanghai, China, the 42.87-kilometre-long (26.64 mi) railway line is used solely for freight services, although passenger services did operate along the line until 2015.

[1] Passenger service on the line started on 1 September 2008, with trains travelling between Shanghai South and Luchaogang, with an intermediate stop at Haiwan.

These trains would use the Jinshan railway between Shanghai South and Jinshan Industrial Park, before switching to the Pudong railway and travelling the entire length of the line.

[2] Passenger service on the line was suspended on 27 August 2015, due to the presence of a hazardous chemicals storage yard near Luchaogang station.

The K8351/8352 and K8353/8354 trains use a set of bottoms, using 4 square Bombardier RZ25T plus a KD25G / KD25K generator car.
