CIT trains are equipped with special devices to monitor the conditions of the track, the wheel-rail force, a catenary-pantograph communications system, and a signal system. Stock is usually painted with yellow bands and the words "高速综合检测列车" (meaning "High-speed Comprehensive Inspection Train") are usually painted on the side.[1] The designs of most CITs are based on originally commercial designs, like the CIT001 (based on CRH5) and CIT400A (based on CRH380A). However, the CIT380A trainset was converted from a prototype of CRH380A (CRH2-150C). Some re-vamped commercial trains used for testing purposes are not designated as CITs and have standard serial numbers appended with a "J" (e.g. CRH380AJ). This stands for "Jiǎn" (inspection).
CRH5J-0501 (original designation, CIT001) is an 8-car trainset based on the CRH5 design, which serves as a 250km/h (155mph) test train.
The CIT001 was ordered by the China Academy of Railway Science on 2 April 2007 and was co-designed by CARS and CNR. The official name is Code Zero Comprehensive Inspection Train. The train is painted with yellow and white striped livery and started test runs on 1 July 2007.[2] It came into service on 6 June 2008.

The CRH3 Hexie is a version of the Siemens Velaro high-speed train used in China on the Beijing–Tianjin intercity railway line, Wuhan-Guangzhou Passenger Dedicated Line, Zhengzhou-Xi'an Passenger Dedicated Line and the Shanghai–Nanjing intercity railway. It is capable of service speed of 380 km/h (236 mph) as the very similar Velaro E used in Spain, but, similarly to the Sapsan, it is 300 mm (11.8 in) wider to take advantage of a more generous structure gauge and thus be able to fit in more seats in a 2+3 layout.
The Wuhan–Guangzhou high-speed railway, also called the Wuguang high-speed railway and short for Beijing–Guangzhou–Shenzhen–Hong Kong high-speed railway, Wuhan–Guangzhou section, is a 968-kilometre (601 mi) high-speed rail line, operated by China Railway High-speed (CRH), connecting Wuhan and Guangzhou, the provincial capitals of Hubei and Guangdong, respectively. It was the world's fastest train service, initially using coupled CRH2C and CRH3C trains which averages 313 km/h (194 mph) in non-stop commercial service.
All Beijing Subway trains run on 1,435 mmstandard gauge rail and draw power from the 750 V DC third rail, except those on Lines 6, 11 14, 16, 17 and 19, which use 1,500 V DC overhead wires. Lines 6, 15, Fangshan, and Changping lines have a designed maximum service speed of 100 km/h (62 mph). The Airport Line is linear motor driven with a designed maximum service speed of 110 km/h (68 mph) All other Lines have a maximum service speed of 80 km/h (50 mph). Currently, Lines 1, 2, 4, 5, 8, 9, 10, 13, 15, Batong, Daxing, Changping, Fangshan, Yanfang, and Yizhuang lines use 6 car B size trains. Initially, the Batong line and Line 13 was originally used 4 car trains and now expanded into six.
The CRH380A Hexie is a Chinese electric high-speed train that was developed by CSR Corporation Limited (CSR) and is currently manufactured by CRRC Qingdao Sifang. As a continuation of the CRH2-380 program it both replaces foreign (Japanese) technology in the CRH2 with Chinese developments and increases its top speed. The CRH380A is designed to operate at a cruise speed of 350 km/h (217 mph) and a maximum speed of 380 km/h (236 mph) in commercial service. The original 8-car train-set recorded a top speed of 416.6 km/h (258.9 mph) during a trial run. The longer 16-car train-set reached 486.1 km/h (302.0 mph).
The CRH6 is a regional/commuter higher-speed train of the People's Republic of China. It is designed by CRRC Qingdao Sifang and will be manufactured by CRRC Nanjing Puzhen at its subsidiary, the CRRC Guangdong Jiangmen Factory. Unlike other CRH types, most CRH6 trains use unique names; only very few CRH6 use Hexie as the train name.
The "fastest" train commercial service can be defined alternatively by a train's top speed or average trip speed.
Vibrant Express, also known as MTR CRH380A or MTR380A is a high-speed train operated by Hong Kong government-owned public transport operator MTR. It was manufactured by Chinese state-owned manufacturer CSR Qingdao Sifang based on the CRH380A Hexie EMUs developed for China Railway. Nine 8-car trainsets were ordered by the Hong Kong government through the MTR Corporation and delivered between 2016-17. It is the first high-speed train produced by CRRC not operated by China Railway.
G-series trains are the fastest train services of China Railway. The trains usually run on dedicated high-speed railways with a designed top speed of 350 km/h (217 mph). The prefix "G" is pronounced as Gao in the CR system, which is short for Gaosu Dongche meaning high-speed EMUs in Chinese. The numbering of G trains are defined by the prefix G followed by a train number. Compared with D-series trains, G-series trains are operated at higher speeds for either part or whole of the journey, and if compared to the D trains sharing the route, may have fewer stops and even overtake these D trains by giving the latter a longer stay at some stations. G trains are also the only type of train that do not permit standees.
Fuxing, also known as the CR series EMU, is a series of high-speed and higher-speed EMU trains operated by China Railway High-speed (CRH) and developed by CRRC. They are the first successful high-speed trains to be fully designed and manufactured in China.
Hexie, also known as the CRH series EMU, is an umbrella term for the multiple unit high-speed and higher-speed trains operated by China Railway under the China Railway High-speed brand. All series of Hexie are based on foreign-developed technology and later manufactured locally in China through technology transfer licenses, with the ultimate goal of China acquiring the know-how and capability to produce high-speed rail trains.
