To meet the rapid development of urban rail transport needs of urban rail vehicle production ,to meet existing and future development requirements of the order ,must be on the existing urban rail vehicle production system and improve the supporting moderate expansion of production scale. The development of urban rail passenger transport system has become the largest city in China to address urban traffic congestion, development of public transport the preferred solution.Give priority to the development of urban public transport, is to promote the healthy development of China's important strategic city. The development of urban rail transit, not only quickly and effectively solve the city's traffic problems and environmental pollution problems, and can actively guide and promote the city's economic development. The comprehensive social and economic benefits are very clear, the development of urban rail transit has become a new bright spot in the national economic development, China's railway rolling stock industry is the transformation of traditional industrial structure, accelerate the development of a new bright spot.At present, China's urban rail transit has entered a rapid development period. According to incomplete statistics, at present, the country's 15 cities of 50 lines under construction, construction of the total mileage of 1,154 km. By 2010 China's urban rail transit lines will reach 55, the mileage of 1,500 km.Up to now, China has 27 cities are preparing the construction of urban rail transit, including 22 cities in the rail transit construction plan has received State Council approval. Based on the data after 2015, China completed and under construction, rail lines will reach 158, the total mileage to more than 4100 km (the current line has been opening and operation of 790 km). By 2020, China will build around the city of about 5000km rail line. Configuration according to the vehicle 6 per kilometer estimates, taking into account both the update and the addition of the vehicle line is expected over the next decade in China's demand for urban rail vehicles in 3000 should be about individual years may reach 4,000.Considering the current rapid development of regional economy and the impact of increased density of vehicles, the market demand will be greater. So the future of urban rail transit vehicle demand, but also to urban rail vehicle manufacturers brought a broad space for development.China's export performance urban rail transit vehicles in recent years, the trend was rising, has been successfully exported Sri Lanka, Bangladesh, Zimbabwe, North Korea and other countries, but also other countries in efforts to extend and penetrate even some developed countries such as Egypt, Libya, Turkey, Korea, New Zealand and other countries.Orders estimated by the production cycle has at least three years, a total of some 6150 vehicles, cars, the average annual 2050. Calculated at 50% of the orders made, the foreign transit vehicles market is expected to 1000. Therefore, as China's urban rail vehicle technology continues to improve, strengthen the capacity of overseas markets, China's annual export market next to 500-1000 is possible.Transit vehicles are high-tech products, compared to the traditional railway locomotive, its reliability, automation, technical accuracy requirements are higher, Therefore, to change the traditional concept of technology, innovation, production and adapt to the requirements of modern high-precision, high performance, high-quality transit vehicles and transit vehicles to be equipped as far as possible to speed up the technical process of localization, Although the localization of equipment has reached 70%, but will continue efforts to acquire more of the core technology for the early realization of all the equipment domestically. The project is based on shares of companies to adapt to long-off of the rapid development of urban rail transport needs of urban rail vehicle production to meet existing and future development requirements of orders for existing urban rail vehicle production system complete set and moderately expand the production scale put forward. CNR is currently the coach of the largest rail manufacturer, CNR is one of the core.Since 1990, the company by the "Ninth Five-Year" key input, the eighth installment of bonds, 200 km EMU technology import and export items and high-speed railway passenger car bogie technology projects invest in high-speed EMU, transit vehicles, bus and truck manufacturing exports has a strong resource base. CNR and Don Long car companies off their high-speed implementation of EMU 350 km expansion to produce 8 (an annual output of about 1 500 350 km EMU). Therefore, this project is CNR for the North Group and Don Long car company off with a 350 km high-speed bogie and the expansion transformation.This project is lCNR under the corporate strategy requires the implemen- tation of steel cut, in order to avoid the waste of assets, the company's steel plant to be, casting and scrap steel plant to be used appropriately modified to Bogie, press preparation, carbon steel parts and aluminum parts production, while addressing the problem of insufficient production area.The project development company based CNR strategic planning, considering the domestic and international demand for mass transit vehicles and the existing production orders, shares of the company for CNR production and the bogie of the production system for technological transformation. Project fully use the existing premises, plant, process equipment and other infrastructure under the premise of partial adjustment of the layout process, to add the necessary equipment, the necessary transformation of plant facilities, upgrade the bogie supporting capacity, to meet production orders and the future city rail vehicle market.The proposed project is the development of mass transit vehicles and the company's strategic development plan to implement the requirements. Implementation of the project in the current situation can play the role of expanding domestic demand, but also to revitalize the equipment manufacturing industry play a catalytic role. Therefore, the reasons the project is fully justified, project construction is necessary. Project is technically advanced and feasible, with obvious economic and social benefits.Benefit from the investment perspective, this project is mainly the use of existing plant, equipment and other facilities, renovation of some existing plants, add some key equipment, the new plant less, you can achieve the production requirements. No land acquisition in this project, but public facilities were more plant transformation, complete transformation of higher cost. Project has launched fast, effective, investment, income and other characteristics better.In summary, the reasons the project is sufficient and reasonable, the project construction is necessary.
