China Railways Comprehensive Inspection Trains (CITs) are high-speed test trains used in the high-speed rail network of China. The trains are normally owned and operated by China Railway or the China Academy of Railway Sciences (CARS).
CIT trains are highly advanced compared to typical modern western standards. They are equipped with special devices to monitor the condition of the track, a wheel-rail force, a Catenary-pantograph communications system and a signal system. Sometimes CITs are used for high speed tests and stock is usually painted with yellow bands on both sides. The words "????????", meaning "High-speed Comprehensive Inspection Train" is usually painted on the side. The build of CITs are based on their original 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 "?"(Ji?n, inspection). Both CITs and "J" trains are usually ordered by China Railway or the China Academy of Railway Sciences (CARS).

List of CIT trains
CRH5J-0501
CRH5J-0501 (Original designation, CIT001) is an 8-car trainset based on the CRH5 design, which serves as a 250 km/h 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 stripes livery and started test runs on 1 July 2007. It came into service on 6 June 2008.

CRH2A-2010
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 line on 31 July 2006. In March 2007 it was converted to be a 250 km/h test train. The train is equipped with ATP, signal parameters, wireless field, pantograph and catenary, track geometry, dynamics and acceleration detecting devices and a circuit-monitoring system.
CRH5J-0501
CRH5J-0501 (Original designation, CIT001) is an 8-car trainset based on the CRH5 design. It serves as a 250 km/h test train.

CRH2C-2061
CRH2C-2061 (formerly CRH2-061C) is the first 300 km/h high speed trainset manufactured by CSR Sifang. The trainset rolled off the line on 22 December 22 2007 and was named CRH2-300, as the prototype of CRH2C. During the test 22 April 2008, CRH2-061C reached a top speed of over 370 km/h (230 mph) on Beijing-Tianjin high-speed rail. During a later test on 11 December 2009, CRH2-061C reached an improved top speed of 394.2 km/h (245 mph) on Zhengzhou-Xi'a high-speed railway line. It now serves as a 350 km/h inspection train, equipped with track inspection, catenaries examination ,and signal inspection devices.
CRH2C-2068
CRH2C-2068 (formerly CRH2-068C) is also a 350 km/h inspection train, equipped with track inspection, Dynamics performance monitor and Pantograph/Catenary inspection devices.
CRH2C-2150
CRH2C-2150 (formerly 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 in April 2010. The eight-car train was modified to a CIT train after series of tests for the design of CRH380A, and was delivered on November 2010.
Formation
CRH380AJ-0201/0202/0203/0206
The CRH400A-001 (initially CIT400A) 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 and rolled off the line on February 22, 2011. The train having a formation of 7M1T, and was designed with a top testing speed 500 km/h.
Development started in June 2010 and the project is named CIT400A. On February 23, 2011, the CRH400A-001 arrived at CARS; after a series of modifying and rectifying, the trainset is set to enter service on March 3. The trainset will do inspection work at the Jinghu HSR.
CRH380BJ-0301
The CRH380BJ-0301 (initially CIT400B) is a 380 km/h CIT train, co-manufactured by CNR Tangshan factory and CNR Changchun factory. The design is based on CNR's CRH380CL trainset, having a formation of 6M2T, with a designed top speed of 500 km/h, and a top operating speed of 400 km/h.

CRH380AM-0204/CIT500/CRH500
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 launch a high-speed test in 2011 and would try to break the then current speed record - 574.8 km/h achieved by French trainset V150, which confirmed CSR was developing the CIT500 (renamed CRH380AM) trainset.
On December 22, 2011, the train, officially named Higher Speed Experimental Train, rolled off of production lines. It is scheduled to enter testing in the near future. The train set is composed of 6 motored cars with a power output of 22,800 kW, which results in an extremely high power to weight ratio.
CRH2J-0205
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.
