. It was an important scientific and technological objective of China's
Eighth Five-Year Plan, and was designed for runs on the
Guangzhou-Shenzhen Railway. The Guangzhou-Shenzhen Railway line will open with an operating speed of , utilizing high-speed passenger trains and the level of potential development of a new type of high speed passenger diesel locomotive. By the end of 1990 development was begun by the Qishuyan Locomotive Works, who modified a DF9 locomotive, changing traction motor gear transmission ratio, thereby increasing the maximum speed from up to . The new locomotive was then tested to obtain the experimental data for high-speed diesel service. In 1991, the Ministry of Railways ordered the new locomotive based on the design plans developed by the Qishuyan plant. Code-named the DF11, the first DF11 number 0001 was completed in December 1992, with the test trials completed in August 1993. The next locomotive, No. 0002, reached the maximum speed of during a test in the National Railway Test Centre (Eastern Suburbs Branch ) in April 1994. After the completion of the trials, the DF11 was formally placed into service on the Guangzhou-Shenzhen High Speed Railway Line in December. Production of the DF11 has stopped production as of 2005, Qishuyan factory produced 459 units total (license number 0001 ~ 0458, 1898), with DF11 1898 being named " The Zhou Enlai "( the number is the same as

s. Maximum braking power from the diesel is , with nominal wheel power at , capable of sustaining operating speeds of up to . Maximum design speed of the
Co-Co trucks is 170 km/h. The cab design incorporates a 25° inclination for streamlining. The locomotive microcomputer control system consists of constant power excitation control, cooling, anti-wheel slip transfer control, fault diagnosis display, with full power to test the resistance of dynamic braking system functions, and electro-pneumatic braking system. The DF11 can haul a passenger train (about 12 cars) up to the maximum balancing speed of on straight track; or a train (about 20 cars) to a maximum balancing speed of .
