With the new transport contract for the Cologne S-Bahn network, the contractual partners go.Rheinland, VRR and DB Regio are relying on tried-and-tested technology in a new design � and it has even won an award! The ET 424 series vehicles that became vacant at S-Bahn Hannover in 2022 have been in use at S-Bahn K�ln since April 2024 following extensive modernization. The vehicles have been given a new design impressing the jury of the prestigious �German Design Award 2024�. The reliable and maximum 25-year-old vehicles, which are not yet at the end of their life cycle, are now gradually being modernized and put back into service for DB Regio. The central element of the redesign is functionality and aesthetics to meet the requirements of today�s passengers. With these improvements, the ET 424 will not only remain an important part of regional transport, but also a symbol of innovation and progress in rail transport.
