Main Types and Characteristics

Fixed Train Washing Machine
Installed on a dedicated car washing line, where the train passes through the cleaning tunnel at low speed to complete the operation. The equipment includes top brushes, side brushes, end brushes, angled brushes, and highpressure nozzles, providing thorough cleaning of the vehicle body.

● Washing time: approx. 5 minutes per train (e.g., Fuxing series)

● Passing speed: 3–5 km/h

● Water utilization: Equipped with a water treatment recycling system; fresh water consumption can be controlled within 800 L per train, with high recycling rate of water.

Mobile Exterior Cleaning Machine
Can be flexibly moved to the train's parking location for cleaning, suitable for depots with space constraints. For example, the mobile car washer used at the Beijing Rolling Stock Depot weighs about 2.5 tons, is batterypowered, and can clean four Fuxing trains (each with 8 cars) on a single charge.

Intelligent Robot Cleaning System
Designed for residual materials (e.g., coal) inside freight train carriages. The cleaning robot can sweep a 70ton capacity carriage in 25 seconds, improving operational efficiency by over 90%.

Ultrasonic Cleaning Equipment
Used for deep cleaning of rail transit components (e.g., gearboxes, calipers). It utilizes ultrasonic cavitation to remove oil and impurities from crevices, suitable for cleaning parts between maintenance steps.
