[1] To make transport more efficient, the construction of a 19.84-kilometre (12.33 mi) long narrow-gauge line to Shixi, with a gauge of 600 mm (1 ft 11+5⁄8 in), began in 1958.
[1] Additional mines near Jiaoba and Yuejin, Sichuan, were also connected to the railway line.
The transport of coal on the remainder was discontinued in 2003, but passenger trains still operated, due to the lack of a road connection.
In May 2004, the local government requested that the line be maintained as a heritage railway, as more and more tourists became interested in it.
[1][3] For the electrified part of the line between Shixi and Yuejin three ZL 14-7 electrical locomotives with four wheels each were purchased in the year 2000.
Four pairs of passenger trains per day pass the full length of the line within 75 minutes in one direction.
Additionally, one or two pairs of trains are used daily for coal transport between Huangcunjing and Shixi.
