The coupling medium room 27 is equipped with a wheel probe temperature control cabinet 26, a flaw detection PLC cabinet 28, a water pump cabinet and antifreeze tank 29, and a coupling water tank 51. The total volume of the coupling water tank 51 and the domestic water tank 13 is 4.5m 3 , exceeding the standard requirements, can effectively extend the mileage of inspection operations.
[0025] The detection system includes a wheel-feeding mechanism 8, a catenary suspension status detection device 18, a three-dimensional rail surface defect detection device 9, a trackside equipment safety inspection device 11, a track status inspection device 12, and a rail profile detection device 14.

Car I is equipped with a locomotive control cabinet, and Car II is equipped with a brake cabinet. The driver's cabs of both cars each house a brake controller reconnected to the BCU. The brake controllers control the train pipe pressure via the BP module to achieve train braking or release. They can also directly control the BC modules of both cars for synchronized braking or release, improving the coordination of the braking actions of the two cars and enhancing the braking performance of the entire train.
[0029] The electrical system includes DC24V vehicle control system and AC380V power supply system.
[0030] Each car's AC380V power supply system is output from the auxiliary transformer, providing power for AC power-consuming equipment on board, such as flaw detection and inspection equipment, air conditioners, and electric heaters. The DC24V vehicle control system is equipped with a vehicle cruise control, which monitors parameters such as vehicle speed and acceleration through the vehicle network control system, and adjusts the locomotive's output power based on these parameters to control the vehicle's operating speed.
