The successful test runs of Digital Automatic Coupling (DAC) trains around Europe bring some rapid developments in Germany. DB is eager to set up 150 pop-up workshops for the DAC retrofitting of wagons. First, the company will prepare its wagons to receive the DAC system. This process will complete in early 2023. After that, wagons will be able to convert to the DAC system in workshops around the country, reducing, thus, their unavailability to customers.
