The so called Tiefa railway is serving a number of collieries in the Diaobingshan region (Liaoning province). There exists also a number of passenger trains. All are now operated by diesel locomotives, but the company keeps a number of steam locomotives in a small museum. Most of them are SY class including No 1772, which is the last standard gauge steam locomotive ever built in China (in 1999). No. 1771 is still operational and is used from time to time as shown in this video. All trains shown are service trains, no charters.
