Chinese Railway 25T type coaches are designed and manufactured to meet the fifth speed increase of Chinese Railway, which absorbs the design and manufacturing technology and experience of 25-type quasi high-speed coaches and speed-raising coaches for many years, and at the same time, adopts the new technology researched in recent years. The design and manufacture of the vehicle carries out the policy of advanced, mature, economic, applicable and reliable, and follows the principles of standardization, serialization, modularization and informationization. The construction speed is 180 kilometers per hour, and the maximum running speed is 160 kilometers per hour. The 25T buses in China are now manufactured with reference to Sifang Bombardier's products.
In December 2003, according to the "Ministry of Railways in 2004, the first new 160km / h speed class bus bidding tender", Changchun Railway Bus, Tangshan Railway Bus, Nanjing Puzhen Vehicle Factory reference BSP's products, began mass production of speed coaches. At the same time, speed coaches are officially designated as "25T type".
Harmony CRH1 electric locomotives, is the People's Republic of China *** and the State Ministry of Railways for China Railway sixth speed, in 2004 to Bombardier Transportation and Qingdao Sifang Bombardier Railway Transportation Equipment Co. "(formerly known as Qingdao Sifang-Bombardier-Bauer Railway Transportation Equipment Co., Ltd., BSP) since 2004, with the CRH series of high-speed electric locomotives, the prototype of which is the Regina C2008, supplied by Bombardier Transportation to the Swedish National Railways. China's Ministry of Railways names all China Railway high-speed (CRH) vehicles jointly designed and produced with the introduction of foreign technology as "Harmony".
The CRH380D, produced by Qingdao Sifang Bombardier Railway Transportation Equipment Co., Ltd (BST), is designed to operate at 350 kilometers per hour, with a maximum operating speed of 380 kilometers per hour and a maximum test speed of 420 kilometers per hour, making it the most advanced train set in China at the moment, and the top of the line globally.
The two groups of CRH380D train sets in Hangzhou are all white, the front are "bullet head", streamlined design, flat and long; the car body marked the highest operating speed: 380 kilometers; the two 380D type train for the 8-vehicle formation, divided into the special car, first-class car and second-class car; their number is known as the "380D", which is the most advanced train set in the world. The number of the famous CRH380D-6601 and 6602 (No. 6601 and 6602 of the two 380D trains are test trains, belonging to the Academy of Railway Sciences, the car is equipped with a lot of testing instruments. Future passenger operation will be the other number of 380D type train, but the appearance is basically the same, in the number of 6602 train side also piled up a lot of sandbags used for train load test), in the front position affixed with a strip of white or silver tape, tape wrapped inside a variety of sensors and data lines.
The two trains also use an improved bogie, equipped with a destabilization monitoring system, which greatly improves safety and reliability. In addition, the total power of the car is 10,800KW, the most for the current domestic train sets, excellent acceleration performance.
