China railways CIT trains

China Railways CIT trains refers to high-speed test trains that are used on the Chinese High Speed railways, CIT means Comprehensive Inspection Train. usually ordered by Chinese Ministry of Rail (MOR) or China Academy of Railway Sciences (CARS).

The trains equipped with special devices to monitor the condition of the track, wheel-rail force, Catenary, Pantograph, communication system and signal system, sometimes the trains are used for speed test.

Basically the built of these trainsets are based on their original commercial designs, like the CIT001 (based on CRH5) and CIT400A (based on CRH380A), the CIT380A trainset was converted from the prototype of CRH380A (CRH2-150C), while some of the trainset was re-equipping of commercial trains, which are not designated as CIT trains by names with nomal series numbers instead.

List of CIT trains

CIT001

CIT001 (Origin name CRH5-000) is a 8-car trainset based on CRH5 design, service as 250 km/h test train.

The CIT001 was ordered by China Academy of Railway Sciences On April 2, 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 color and started test run on July 1, 2007.^[1] came into service on June 6, 2008.

CRH2 type trainset

CRH2-010A

CRH2-010A is the first ever High Speed test train of China, it is also the first CRH2 trainset manufacturered by CSR Sifang, the trainset rolled-off line on July 31, 2006. in March, 2007 it has converted to be 250 km/h test train. The train is equipped with ATP, the signal parameters, the wireless field, Pantograph and Catenary, track geometry, dynamics and acceleration detecting devices and circuit monitoring system.^[2]

CRH2-061C & CRH2-068C

CRH2-061C is the first 300 km/h High Speed trainset manufacturered by CSR Sifang, the trainset rolled-off line on December 22, 2007.^[3] and was named CRH2-300, as the prototype of CRH2C.During the test on April 22, 2008, CRH₂-061C reached a top speed of over 370 km/h (230 mph) on Beijing-Tianjin high-speed rail.^[4] During the test on December 11, 2009, CRH₂-061C reached a top speed of 394.2 km/h (245 mph) on Zhengzhou-Xi'an high-speed rail.^[5]

CRH2-061C now service as 350 km/h inspection train, equipped with track inspection, Catenaries examination and signal inspection devices.

CRH2-068C is also a 350 km/h inspection train, equipped with track inspection, Dynamics performance monitor and Pantograph/Catenary inspection devices.

CRH380A type trainset

CIT380A

CIT380A is a 350 km/h High speed comprehensive inspection train, it is converted from The prototype vehicle of CRH380A, the original train, CRH2-150C was rolled off on April, 2010, the eight-car train was midofied to a CIT train after series of test for the design of CRH380A, and delivered on November, 2010.

CIT400A (CRH400A-001)

The CRH400A-001 is the first ever 380 km/h CIT train of China, based on the CRH380A design, the 8-car trainset is manufactured by CSR Sifang factory, rolled-off line by February 22, 2011.^[6] fomation 7M1T, designed top testing speed 500 km/h.

the develop starts from June 2010 and the project is named CIT400A, on February 23, 2011 the CRH400A-001 arrives at CARS, after a series of modify and rectify, the Trainset is set to enter service at March 3, the trainset will do a lot of inspection work at the Jinghu PDL.

CIT400B (CRH400B-001)

The CIT400B is a 380 km/h CIT train, Co-manufactured by CNR Tangshan factory and CNR Changchun factory,^[7] the design is based on CNR's CRH380CL trainset, fomation 6M2T, designed top speed 500 km/h, and top operating speed 400 km/h.
