Standards Development
Provide specification and requirements to enable interoperability of freight wagons, freight locomotives, and external power supply with digital automatic coupler (DAC) on the European railway network.
Specification of the DAC electrical coupler interfaces for use in rail freight operation:
- Interoperability interface specification of the electric coupler: contact properties, electrical connector etc. taking into account the contact requirements from the respective standard for data communication
- Parameters of the voltage supply network: voltage type, level, electrical current, tolerances etc.
- Insulation, electric safety, and electromagnetic compatibility requirements
- Requirements for power cable, cable routing from coupler to wagon, protection for power and communication cable, using the communication cable defined in the respective standard for data communication
- Electrical interface from coupler cable to the wagon
- Requirements due to functional safety goals
- Test methods for the electric coupler and the coupler cable
Introduction of the DAC in European rail freight supports European Green Deal by increasing the efficiency of rail freight, e.g. with less time in shunting and longer trains up to 1,500 m.
The high number of freight wagons in Europe requires standardisation of the DAC interoperability interfaces. This includes the DAC electric coupler interfaces.
