In November 2003, the Ministry of Railways of China and the former China South Locomotive, CNR Group and its key enterprises jointly formulated the Outline for Accelerating the Modernization of Railway Locomotive and Vehicle Equipment, and selected six locomotive manufacturing enterprises as the introduction of advanced technology and independent innovation. The subject. At the beginning of December 2004, according to the state arrangement, Siemens and former CSR Zhuzhou Electric Locomotive Works Co., Ltd. obtained an order for 180 double-axle eight-axle heavy-duty freight AC drive electric locomotives from the Ministry of Railways of China, with a total value of about 7.34 billion. Yuan Renminbi, of which Siemens' share is about 350 million euros, while Zhuzhou Electric Locomotive Works has a share of 52.6%, about 3.86 billion yuan.

        The HXD1 project was designed by the Siemens Transportation Group headquarters in Germany, and the Zhuzhou Electric Locomotive Works was produced in Zhuzhou, Hunan. The locomotive consists of two identical four-axle locomotives. It uses AC-DC-AC drive, water-cooled IGBT traction inverter, variable frequency asynchronous traction motor, "SIBAS 32" microcomputer control system and train communication network. The rated power is 9600. Kilowatts, with a maximum operating speed of 120 km / h, and equipped with "Locotrol" remote reconnection control system, suitable for multi-machine distributed heavy-duty traction. Up to the current total production and production: 300 units, all running on the Daqin Railway.

Development process

 China and the German government signed a project procurement memorandum on December 6, 2004

Project launch in January 2005

 In December 2005, Siemens, the Zhuji Federation and the Ministry of Railways of China confirmed the technical plan.

In February 2006, the technical design proposal passed the technical review of the Ministry of Railways.

On November 8, 2006, the first locomotive was completed and offline.

 Type test and comprehensive performance test were completed from February to April 2007

In May 2007, the pilot application of the Daqin Railway was put into use.

 At the end of July 2007, it began to take the traction task of the 20,000-ton combined train on the Daqin line.
