DAC

Digital Automatic Coupler for Freight Wagons

Dellner is one of a select group of suppliers offering Digital Automatic Couplers (DAC) for further integration into rail freight. At the end of September 2021, the “Latch” type coupler was selected as the basis for the future DAC for the freight rail industry. 

Digital Automatic Coupling is not a stand-alone technology, but rather the foundation for “fully digital freight train operations” that will help make the ambitious transformation in European rail freight a reality. Use cases show that Digital Automatic Couplers enhance the competitiveness of rail freight by reducing turnaround times, improving the overall carrying capacity of freight trains and strengthening the reliability of rail freight. 

DAC will enable the implementation of train protection systems and better braking capacity, leading to improved traffic planning and accessibility. This new type of coupler for freight trains will eliminate the need for workers to enter the Berne Rectangle and perform repeated manual tasks during shunting and assembly operations. This makes work safer and preserves the health of railway workers.
