On September 30, 1970, China's first 6000 hp high-power hydraulic transmission trunk line freight diesel locomotive was officially named Beijing type, car number 6001.
【At that time, the world's largest single-section power hydraulic transmission diesel locomotive】
In October 1969, Beijing Erqi Locomotive and Rolling Stock Factory, together with the Locomotive and Rolling Stock Research Institute of the Iron Science Institute, dalian thermal locomotive research institute, Qishuyan locomotive and rolling stock technology research institute, Datong Locomotive Factory and other units jointly began to design.
On September 30, 1970, The Erqi Locomotive and Rolling Stock Factory manufactured China's first 6,000-horsepower high-power hydraulic transmission trunk freight diesel locomotive, officially named beijing type, vehicle number 6001.
Beijing type 6001 locomotive adopts a two-unit structure, equipped with two 12V240ZJ diesel engines and hydraulic transmission devices.
The locomotive axle type D-D was also the world's largest single-section hydraulic transmission diesel locomotive at that time.
The locomotive is designed for mountain traction of heavy freight trains, adapted to ambient temperatures, taxi 40 degrees.
The main features are large traction, low fuel consumption, simple structure, easy to operate, easy to maintain,
Suitable for driver maneuvering in transition from steam locomotives to diesel locomotives.
The locomotive is equipped with two sets of 12240Z diesel engines, and the vehicle quality is 184 tons.
It is equipped with two four-axle bogies, 8-axis drive, fully symmetrical arrangement, and a cab at both ends.
In 1972, after leaving the factory, the No. 6001 car was delivered to the Fengtai locomotive maintenance section of the Beijing Railway Bureau for trial, and between Fengtai West and Shijiazhuang, the traction truck was tested, and the distance was 18334 kilometers.
Vehicle 6001 did not undergo normal traction tests according to the part standard. [Because the 12240Z diesel engine configured at that time has not yet passed the ministerial appraisal, there are some quality problems, and the locomotive itself is the first crab, some quality problems need to be exposed in the test, improved]
In September 1974, the 12240Z diesel engine passed the ministerial appraisal.
In December 1977, the Erqi Factory renovated the No. 6001 car.
In December 1977, the Ministry of Railways and the Beijing Railway Bureau officially issued the Notice of the Ministry of Railways (77) Iron Locomotive Zi No. 1291 "Notice on Arranging the Operation Test of Beijing Type 6001 Diesel Locomotive".
The operation test group is composed of the Beijing Bureau, the Beijing Branch Bureau, the Fengtai Machine Maintenance Section and the Erqi Factory, with the Beijing Bureau as the team leader and the Erqi as the deputy team leader.
100,000 km of traction operation test for locomotive 6001.
In February 1978, it was put into use between Fengtai West of Jingshan Railway and Nancang in Tianjin, Zhangjiakou to Fengtai West of Fengsha Railway, and Fengtai West of Beijing-Yuan Railway to Lingqiu, and completed the traction test of 100,000 kilometers according to the requirements of the current traction quota and operation map of the line, with a total of 104935 kilometers.
During the operation, the exposed problems were improved to meet the requirements of 4,000 tons of traction in the straight section and a speed of 80 kilometers per hour.
In July 1979, the operation assessment and dynamic performance test were completed, and then the Fengtai locomotive maintenance section was put into use.
In June 1981, it was transferred to the Shijiazhuang locomotive depot and put into operation on the Shide Railway.
Later, the whereabouts are unknown.
