Train Washing Plants

We develop efficient washing plants adapted to the needs of each client, both for the location and for the type of trains or the washing programmes required.

Aquafrisch designs, manufactures and supplies washing plants according to each customer’s specifications. In our designs we take into account both the space available and the type of trains to be washed:

Subways / trams

Suburban / Regional

High speed

The modularity of our plants allows us to adapt easily to the particular surfaces of each train model , being able to wash sides, front / back, shoulders, skirt and roof. As a provider of water treatment solutions, our plants include our own systems specifically designed for the recycling of water used in washing, either by chemical systems, physical systems or a combination of both.

We also include specific treatment of fresh water in order to demineralise it for use in the final stages of washing. We integrate the control of the washing plant and its water treatment under the same system. With the most advanced control systems on the market, we develop easy-to-learn programs with the possibility of connecting to the Internet and centralized control systems (SCADA, CBTC, MMS, or similar).

Mobile train wash plants

If sufficient space is available, equivalent to the length of the train, mobile washing plants are the ideal solution for high quality washing. In their design, we take into account the model of the train and its washing areas (cabins, sides, shoulders, skirts, underframe, roof), the washing programmes, the water recycling system and the degree of automation.

The train remains stationary while two self-propelled semi gantries on each side move longitudinally. Each semiportal is equipped with a nozzle and vertical or horizontal brushes, whose activation per route, in addition to the speed of movement of the Semi gantry, can be programmed individually.

In order to improve the washing efficiency, the direction of rotation of the brushes is opposite to the advance of the semi gantries. In addition, recycled water is used to reduce tap water consumption by up to 80%. Rinsing can be carried out with tap water, decalcified or demineralised. The identification of the trains to be washed can be done manually or automatically, by means of RFID recognition system. In this way, the system loads specific washing programs according to the identified train.

Fixed train wash plants

Fixed washing plants are the ideal solution for fast train availability or if the washing tray has little space. In their design, we take into account the model of the train and its areas to wash (cabins, sides, shoulders, skirts, under frame, roof) washing programs, the water recycling system and the degree of automation.

The train advances through the washing tray. After a first stage of spraying water and detergent, the train is washed with brushes. To improve the efficiency of the washing, the direction of rotation of the brushes is opposite to that of the train. In addition, recycled water is used to reduce tap water consumption by up to 80%. The final stages are rinsing with tap water, decalcified or demineralised. To improve the final appearance of the train, we can include wax dosage in the rinsing stages and a nozzle drying stage.

Thanks to the modular design of our plants, we can program different types of washing, for example, including or not the washing of cabins, roof, shoulders or skirts. The identification of the trains to be washed can be done manually or automatically, by means of RFID recognition system. In this way, the system loads specific washing programs according to the identified train. The washing can be unidirectional or bidirectional.
