In 2005,approved by the former Ministry ofRailways, the company became the firstprofessional manufacturer in Chinathatintroduced 10 critical matching technologies concerning electric multiple unit (EMU) from Europe, includingpotablewater, greywater & vacuum sanitation system technology. Atpresent, thecompany is the first R&D and manufacturing unit of potablewater, greywater & vacuum sanitation systems for China's high-speed rails(Fuxing, CRH), and has delivered more than 25,500 railway vehicles tothe globalrailway market (Fuxing, CRH, Green Giant and overseas markets), which have been extensively applied in whole series ofmodels involving speed grades of120km/h, 200km/h, 300km/h, 350km/h and 400km/h, making the companya worldleader in the field of potablewater, greywater & vacuum sanitation system for railway vehicles.

Revolving on the core product of vacuum sanitation system forhigh-speed trains, the company has expanded its productcategory tomore than 5,000 types encompassing high-speed railintelligent rest room modules, electric teastoves, fine welding, pipeline systems and fine processing components. Meanwhile,resorting to high-speed rail equipmenttechnology, the company plans to enter the urban railtransit industry, expecting to provide whole life-cycle services such as design, manufacturing andin-frame overhaul of critical components for urban rail vehicles and realize "dual-trackparallel" of high-speed rail and subway.
