In the afternoon of September 16, another type of high-end electric locomotive with double-current system made for South Africa by CSR struck a pose on the stage of Zhuzhou. African owners and Chinese development team from CSR Zhuzhou Electric Locomotive Co., Ltd. shared the honorable moment before the electric locomotive (Model: 21E) with South African cultural factors.

    Before then, CSR has provided 95 electric locomotives for South Africa and their excellent quality and perfect performance upon launch laid a good foundation for CSR's winning the bidding of the large order, the second batch of electric locomotives valued 2.1 Billion Dollars. The second batch of locomotives is the "upgraded" electric locomotives designed on the basis of customers' demands.

    Under the direction of Liu Youmei, the academician of Chinese Academy of Engineering and the director of committee of experts in CSR Zhuzhou Electric Locomotive Co., Ltd., professional R&D team, project management team, process & technology team, and quality management team cooperated with absolute sincerity during the operation of the project. They frequently organized the review on technology and process and repeatedly calculated and tested, strictly controlling the quality according to international standards to create the product diligently. 

    Excellent contractual capacity in international projects is one of the core competitiveness of CSR. The first electric locomotive of the previous 95 electric locomotives project exported to South Africa by CSR Zhuzhou Electric Locomotive Co., Ltd. was developed within only 8 months. At present, the safe operation mileage of the on-line operating locomotives reaches 157,703 km. In 2014, CSR Zhuzhou Electric Locomotive Co., Ltd. has more than 50 domestic and overseas projects under operation, which exceeds previous years. The number of rail transit equipment manufactured comes to the historical maximum peak and the first-rate projects operation capacity will provide high-end rail transit products for each line. 

    It's known that the four-axis freight electric locomotives with double-current system (DC and AC) are able to operate under 25 KV AC voltage and 3 KV DC voltage with power of 3,000 KW and max speed of 100 km per hour. Microcomputer network control system is adopted among locomotives and 8 locomotive heading can be realized, as well as heading with diesel locomotives. According to the project plan, some locomotives of the second batch will be assembled, debugged, and delivered in local South Africa.

    According to Suo Jianguo, the Vice-General Manager and Chief Engineer of CSR Zhuzhou Electric Locomotive Co., Ltd., these electric locomotives have absorbed the essence of the electric locomotives specially designed for Chinese coal transporting railway lines to customize the busiest coal transporting railway lines in South Africa and are the "upgraded version" of 95 electric locomotives previously exported to South Africa. On one hand, the axle load of locomotives is designed as 26 tons with the traction increasing therewith, which is more suitable for coal transporting; on the other hand, more advanced technology of wire electronic control air braking system (ECP) is adopted. The electrical signal controls air braking in the carriages, which largely increase the braking response speed of long and large marshalling carriages and corresponding safety and reliability of trains.

2 locomotives in the first batch will be accepted and delivered before February 28, 2015. Wishing our electric locomotives output could improve local transport efficiency and drive local economic development in South Africa.
