In order to fulfill the TSI standards for tunnel safety, Hilton offers a unique solution based on road-rail vehicles that can be operated in coupled mode as rescue train. The control system on these vehicles allows to drive in single mode or coupled mode on track. It is also possible to couple the vehicles to rail wagons for example for wagons with extra water tanks, first aid units, etc. All superstructures are specially designed for tunnel operation. Modern overpressure rescue chambers allow to have a safe room with clean air for the fire fighters or evacuated passengers. The vehicles can be used as multifunctional firefighting vehicle, water carriers, passenger evacuation vehicles etc.
