Environmental measures

  • Since April 2024, the first of 24 planned completely modernized electric multiple unit (EMU) 424 series cars, which were originally built in 1999/2000 for the Hanover S-Bahn (metro), have been in service for the Cologne S-Bahn (metro). These will be followed by the 99 trains in the other EMU series. The comprehensive modernization project not only improves passenger comfort, but also saves resources compared to a new purchase.
