The Dongfeng -11 diesel locomotives (DF11), is a quasi- high-speed diesel locomotive , from China Qishuyan Locomotive Works Manufacturing Co. used by the China Railway.

Overview

China Railways DF11 Diesel-electric locomotive is a semi-high-speed passenger locomotive. It was an important scientific and technological objective of China's Eighth Five-Year Plan, and was designed for 160 km/h runs on the Guangzhou-Shenzhen Railway. The Guangzhou-Shenzhen Railway line will open with an operating speed of 160km/h, 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 140 km/h up to 160 km/h. 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 183km/h 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 No. locomotive named " Zhou Enlai No. "(license number to Zhou year of birth name), belonging to Shanghai Railway Administration Shanghai Locomotive Depot.

The DF11 diesel locomotive is equipped with an AC-DC electric transmission, 16VZSOZJA diesel engine, 1 three-phase AC synchronous alternator model JF204C, and 6 ZD106 DC traction motors. Maximum braking power from the diesel is 3,610 kW, with nominal wheel power at 3040 kW, capable of sustaining operating speeds of up to 160 km/h. 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 640 t passenger train (about 12 cars) up to the maximum balancing speed of 167 km/h on straight track; or a 1100 t train (about 20 cars) to a maximum balancing speed of 143 km/h.

In addition, the DF11 locomotives are designed for Xinjiang The Urumqi Railway Bureau plateau type of configuration, mainly to increase the output of power, and installation of sound bilateral air intake / air filtration / filter sand unit, and to increase the gear ratio change from the 76:29 to 65:22 , increasing starting traction and sustained traction. However, the maximum speed is reduced to 153 km/h.

DF11 Model No. 3001

August 2000, DLoco trial was a quasi- high-speed lines of passenger diesel locomotives , numbered as No. DF11 3001. The locomotives and the Qishuyan Locomotive Works of the production easterly of 11 locomotives and no technical contact, based on Dongfeng 4D diesel engine car-based development is with Dalian Locomotive Plant Product Dongfeng 8B -type car No. 3001 (No. DF8B 3001, officially named Dongfeng 8D type) on the same platform developed passenger locomotive, officially named the ' Dongfeng 11D type ' . Locomotive equipped with 12V280/320ZJ type (piston stroke 320 mm) medium-speed engine, diesel power is 3820 kilowatts loading (5200 hp). Maximum operating speed of locomotive 170 km/h.

Gai Xingji produced only one car, and no amount of post- production. After an engine factory in the Pei Zhu Jinan Railway Jinan Locomotive Depot test application was mainly responsible for pulling the express train, but the process in the use of locomotive failures repeatedly. Locomotive then be sent back to Dalian Locomotive Works Archive, there are rumors that the locomotives have been scrapped dismantling.

Major incidents

Main article: 2008 Shandong train collision

On 28 April 2008, DF11 locomotive DF11-0400, hauling Train No. 5034, collided with the derailed Train No. T195 in the Jinan-Zibo section of the Jiaoji Railway. The DF11-0400 locomotive was declared destroyed beyond repair and later scrapped.
