This high-tech train wash machine senses the different train car shapes and can be set up to wash the train entering from either end of the wash bay. The train wash system can wash the train front, roof and end in one run. The system is available with multiple wash programs to better suit the customer's wash needs. The train wash system has high density brushes for the side and roof. The machine can be delivered with a dryer/blower system. We also provide systems which can register and identify trains. This transponder will help collect data and automatically select different wash programs for different style of trains.
