On March 20, China's first subway train for India was offline in CSR Nanjing Puzhen Rolling Stock Co., Ltd. The train with independent intellectual property right will be used in India's largest city Bombay. This is a breakthrough of China's rail transit equipment in the Indian market as well as China's first practice of exporting an A-type top subway train, marking an increase in the international competitiveness of China's rail transit equipment.
In the sun, the train was as pretty as a bride: gorgeous decorations, beautiful butterfly film, smooth stainless steel body and rich Indian tone.
In May 2008, CSR Puzhen stood out of international large companies to get an order of 18 wide-body and large-capacity rail transit vehicles 108 carriages as the winner of the international bid for subway trains in Bombay, India. In the past 22 months, guided by the lean concept, CSR Puzhen made all-round technical breakthrough on the independent R & D platform, rapidly tackled design and manufacturing problems according to large transportation capacity, complicated running environment, high technical requirements and other characteristics of subway in Bombay, and particularly achieved major breakthroughs in 25,000V AC-DC-AC technology, development of super-wide, high-strength and light stainless steel body, sound insulation and noise reduction technology, and bogie R & D.
Apart from advanced performance of domestic A-type subway trains, the train for Subway 1 in Bombay has many unique characteristics. It uses 25,000V AC-DC-AC technology first at home, with a body width of 200mm higher than domestic A-type subway trains and a compressive and tensile strength of 50% higher than domestic stainless steel bodies; each train has a rated transportation capacity of 390 passengers, 72 more than that of domestic A-type trains; with 17-ton axles, it is marshaled by two motors and two trailers and driven in a full-automatic manner.
As a coastal city, Bombay is hot, rainy and dusty throughout the year, lines have many curves and small turning radii, and the average station distance is only 980m. The train not only fully reflects the human-oriented requirements for bright colors in internal and external design, but also gives full consideration to the requirements for running environment, noise reduction and dust prevention, and ultra-short fast start and braking. With a maximum running temperature of 55℃, an internal noise loudness of 66dB, 3 dB lower than that of domestic A-type trains, a running humidity of 100%，a minimum curve radius of 80m and a maximum running speed of 80km/h, it can fully meet the requirements of complicated and volatile terrains and climate and environment changes in Bombay.
CSR is China's largest rail transit equipment manufacturer, under which Puzhen is a major development base of China's city subway and inter-city trains. The company has got orders for several city subway and inter-city projects in Shanghai, Nanjing, Hangzhou, Suzhou, Shenzhen and on Guangzhou-Dongguan-Shenzhen line, and gained rich successful experience in business operations. Through integration of core technologies, independent R & D of manufacturing technologies and introduction of diverse auxiliary equipment, CSR Puzhen has explored a road of independent innovation with an international industrial competitive edge, laying a solid foundation for globalization.
According to the source, the first wide-body large-capacity subway train for Bombay will be shipped from Shanghai to Bombay on March 23 and put into business operation after a series of running tests on main lines.
