As a secondary vehicle are rail vehicles designated to be used for certain restricted service, auxiliary and special purposes. According to the new uniform legal provisions for international rail traffic, this vehicle category is referred to as special vehicles .


The EN 14033-1 standard divides rail-bound construction and maintenance machines into the following categories based on their design:

  • Machines that may be set in trains with a speed greater than 100 km / h:
    • Self-propelled machines that can travel at speeds greater than 100 km / h: Category 1
    • Self-propelled machines that can travel at a speed of less than 100 km / h: Category 2
    • Non-self-propelled machines: Category 3
  • Machines that may be set in trains with a speed of less than 100 km / h:
    • Self-propelled machines: Category 4
    • Non-self-propelled machines: Category 5
  • Machines that may not be placed in trains:
    • Self-propelled machines: Category 6
    • Non-self-propelled machines: Category 7

Road-rail vehicles are divided into categories 8 and 9. Depending on the categorization, the standard prescribes further technical regulations. National particularities can further restrict or supplement the specifications of the standard.


On the German railways, a distinction is made between auxiliary vehicles and regular vehicles . While the latter must fully comply with the building regulations of the railway building and operating regulations , this is only required for ancillary vehicles to the extent that it is necessary for the special purpose the vehicles are to serve.

In Germany, auxiliary vehicles are divided into the following categories:

From an operational perspective, ancillary vehicles in Germany are classified as either heavy ancillary vehicles (Schwerkleinwagen) or small cars , depending on their vehicle mass, depending on whether the safe functioning of wheel sensors and track vacancy detection systems is guaranteed or not. Small cars are therefore only allowed to run on restricted journeys . Heavy auxiliary vehicles that are to be used on routes with inductive train control must be equipped with point-type train control. According to the railway building and operating regulations , auxiliary vehicles that travel faster than 20 km / h must be equipped with a safety driving mechanism. In order for secondary vehicles to be allowed to be placed in trains, they must be equipped with the appropriate pulling and buffing equipment and designed for the forces acting on them.


In Switzerland there is no uniform designation for ancillary vehicles, and there is no special legal status for them. Most of them are grouped under the heading of self-driving company cars and construction machines .
