Road-rail dual-purpose vehicles refer to special vehicles that can run not only on railway tracks, but also on general roads and even in the wild. In the early days, it was mainly used in the military. Hyundai mainly undertakes emergency tasks such as maintenance and rescue of railway lines and along the lines. Road and rail vehicles are required to be able to switch between road and rail quickly and easily. It is usually realized through the hydraulic lane changing slewing device on the chassis and the railway running guide wheel device that can rise and fall at any time. With the guide wheel device, the general rubber tire wheel can run straight along the rail. Because this vehicle requires a certain amount of towing and carrying capacity, it can play a unique role in the event of an interruption or blockage of a railway line due to a disaster. The dedicated road and rail vehicles include: catenary repair vehicles in electrified traction sections, excavators for mountain railway repairs, emergency tractors, generator vehicles, fire trucks, fast bridge erection vehicles, etc.

Road and rail vehicles are multi-purpose vehicles, light and flexible, with high running speed and wide range. It can be equipped with different equipment according to the operation requirements to carry out various operations, such as lifting, digging, loading and unloading, snow removal, cleaning lines and erecting catenary wires, checking and maintaining the equipment on the catenary, rescue and disaster relief, etc

Vehicle Type
The road-rail dual-purpose vehicle driven by rubber wheels is driven by rubber wheels no matter on the road or on the railway, and is guided by special guide wheels when running on the railway. The guide wheel type road-rail dual-purpose vehicles designed and produced in China generally have rubber tires that are seriously worn on the rails, and are prone to derailment during operation, especially when crossing the turnout.
In order to prolong the life of the rubber tires and reduce the burden of the rear rubber tire driving wheel on the track, the load of the rear rubber tire driving wheel and the rear guide wheel must be properly distributed to ensure the driving performance of the rear rubber tire driving wheel and the rear to the guide wheel. Rail tracking performance.
On the dry rail surface, the friction coefficient between the rubber wheel and the rail is 0.4-0.6, but in rainy and snowy weather, the attenuation is serious.
The internal combustion type road-rail dual-purpose vehicle has stable power output and is often used in railway maintenance projects and emergency use.
Battery-type road-rail vehicles are affected by the performance of the battery. The power output of the battery, the ambient temperature, and the age of the battery have an impact on the power output.

Operation method
Some road and rail vehicles have two control methods: manual driving and wireless remote control. The road-rail dual-purpose vehicle is equipped with a fixed automatic coupler, which has the function of hooking up with the automatic coupler of the subway and other trains, and the train driver's platform has an automatic uncoupling function.
