The DF9 (Chinese: 东风9) is a first Chinese semi-high-speed diesel locomotive with speed 160 km/h (99.4 mph), which was successfully developed by Qishuyan Locomotive and Rolling Stock Works in 1990. As a China's Eighth Five-Year Plan scientific and technological project, the DF9 diesel locomotive adopts wheel-to-hollow shaft traction motor full suspension drive system, high-flexibility second-series round springs, lightweight body and other technologies. Although only 2 units of DF9 were produced and scrapped and dismantled in 2011, it laid the foundation for the development of DF11 diesel locomotives.

Overview edit

It belongs to the China's Eighth Five-Year Plan one of the key national science and technology projects, it was not only the second locomotive equipped with a 280/285 series diesel engine after the DF8 diesel locomotive, it was also the electric transmission diesel locomotive with the highest single-machine power in China's railways at that time. The power unit of the DF9 diesel locomotive is a 16V280ZJA diesel engine with an installed power of 3,610 kW (4,840 hp).

A DF9-0001 with a construction speed of 140 km/h (87.0 mph) was completed in October 1990. In April 1991, in order to cooperate with the Guangzhou–Shenzhen Railway scientific and technological project test, Qishuyan Locomotive and Rolling Stock Factory trial-produced DF9-0002 locomotive with a structural speed of 160 km/h (99.4 mph). In March 1992, DF9-0002 set a speed record of 161 km/h (100.0 mph) on the National Railway Test Center, Beijing.
