China Railway comprehensive inspection trains

CRH5J-0501 at Beijing South.

CRH5J-0501 (original designation, CIT001) is an 8-car trainset based on the CRH5 design, which serves as a 250 km/h (155 mph) 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.

CRH2A-2010 (formerly CRH2-010A) is the first high-speed test train in China and the first CRH2 trainset manufactured by CSR Sifang. The trainset rolled off the production line on 31 July 2006. In March 2007 it was converted to be a 250 km/h (155 mph) test train. The train is equipped with ATP, signal parameter monitoring, wireless field monitoring, pantograph and catenary monitoring, track geometry monitoring, dynamics and acceleration detecting devices and a circuit-monitoring system.[3]

CRH2C-2061 (formerly CRH2-061C) is the first 300 km/h (186 mph) high speed trainset manufactured by CSR Sifang. The trainset rolled off the production line on 22 December 22, 2007[4] and was named CRH2-300, as the prototype of CRH2C. During a test on 22 April 2008, CRH₂-061C reached a top speed of over 370 km/h (230 mph) on Beijing-Tianjin high-speed rail[5] and on 11 December 2009 reached an improved top speed of 394.2 km/h (245 mph) on the Zhengzhou-Xi'an high-speed railway line.[6] It now serves as a 350 km/h inspection train, equipped with track inspection, catenary examination, and signal inspection devices.

CRH2C-2068 (formerly CRH2-068C) is a 350 km/h (217 mph) inspection train, equipped with track inspection, dynamics performance monitor and pantograph/catenary inspection devices.

CRH2C-2150 (formerly CIT380A) is a 350 km/h (217 mph) high-speed comprehensive inspection train. It is converted from the prototype vehicle CRH380A. The original train, CRH2-150C, was rolled off the production line in April 2010. The eight-car train was modified to a CIT train after a series of tests for the design of CRH380A, and was delivered in November 2010.

The CRH400A-001 (initially CIT400A) is the first ever 380 km/h (236 mph) CIT train of China, based on the CRH380A design. The 8-car trainset was manufactured by CSR Sifang factory and rolled off the production line on February 22, 2011.[7] The train has a formation of 7M1T, and was designed with a top testing speed of 500 km/h (311 mph).

Development on the CIT400A started in June 2010. On February 23, 2011, the CRH400A-001 arrived at CARS; after a series of modifications to rectify problems that occurred during testing, the trainset was set to enter service on March 3, performing inspection work on the Jinghu HSR.

CRH380BJ-0301 on Beijing–Kowloon railway

CRH380BJ-A-0504, another inspection train built for low temperature conditions in Northeast China, at the China Academy of Railway Sciences.

The CRH380BJ-0301 (initially CIT400B) is a 380 km/h (236 mph) CIT train, co-manufactured by the CNR Tangshan and CNR Changchun factories.[8] The design is based on CNR's CRH380CL trainset, with a formation of 6M2T, a designed top speed of 500 km/h (311 mph), and a top operating speed of 400 km/h (249 mph).

CRH380AM testing on the Beijing–Shenyang section of Beijing–Harbin high-speed railway

On December 7, 2010, during the 7th World High-speed Rail Conference held in Beijing, an officer from the CSR Group confirmed that China would perform a high-speed test in 2011 in an attempt to break the then current speed record of 574.8 km/h (357.2 mph) achieved by French trainset V150.[9] This confirmed that CSR was developing the CIT500 (later renamed CRH380AM) trainset.[10]

On December 22, 2011, the train, officially named "Higher Speed Experimental Train",[11] rolled off the production line. It is scheduled to enter testing in the near future.[12] The train set is composed of 6 motored cars with a power output of 22,800 kW (30,575 hp), which results in an extremely high power to weight ratio.[13]

CRH2J-0205 is a modified CRH2E. Converted from CRH2-139E. The train set is painted in an orange livery and is used for inspection work.

CR400BF-J-0511

CR400BF-J-0511 is based on the CR400BF-C which was designed for the Beijing–Zhangjiakou intercity railway. The train has its bogies of cars 3 and 6 equipped with eddy current brake.
