100 days of the new S-Bahn trains for Berlin and Brandenburg – a first assessment

Berlin’s new S-Bahn trains are a hundred days old – still so very young, yet already proving highly reliable. The new 483/484 series has passed its baptism of fire and also proved itself during the spell of cold winter weather in February: The trains successfully defied snow, ice, and wind.

The first train punctually entered service at 0.01 a.m. on New Year’s. Since then, the ten pre-series trains have been running on Line S47 (Spindlersfeld – Hermannstraße) and have replaced the old 485 series trains.

Passengers are happy and feedback from the driver cabs is also positive: Drivers praise the train’s power, strong braking capacity, and smooth and quiet operation.  

S-Bahn head Peter Buchner: “We’re very satisfied with the new trains. The intensive two-year test phase is now paying off since the trains covered every corner of the Berlin S-Bahn network before entering passenger service. The close collaboration between the manufacturer and operator was a very important factor during construction and commissioning for ensuring that a train would be delivered that optimally meets the specific conditions in Berlin. We also greatly benefited from our many years of experience in S-Bahn operations. A big thank you to Siemens Mobility and Stadler for the trusting partnership!”

With the new trains, S-Bahn Berlin not only offers its passengers greater comfort, but also provides more capacity for our customers. When all the 21 two-car units and 85 four-car units ordered from Siemens Mobility and Stadler have been delivered by the end of 2023, a total of 106 new quarter trains will be in operation.

Beginning this summer, the first series trains will be delivered and join the 483/484 fleet once they have been accepted.

Nicklas Meyer, Chief Vehicle Engineer and Technical Project Manager at Stadler for Berlin’s new S-Bahn: “As manufacturer, we’re still intensively accompanying the ongoing trial passenger operations. This way, we can ensure that further operational findings flow directly into the production of the series trains. Looking back at the first hundred days, we as manufacturer are also very satisfied with the trains’ technical performance. In particular, the period of sub-zero temperatures in February confirmed our concept. We’re convinced that the first S-Bahn to be equipped with air conditioning will also prove itself at the peak of the summer.”


Gerald Winzer, VP Regional Train Projects, Siemens Mobility: “We’re proud that the new S-Bahn for Berlin is running so smoothly. The new S-Bahn trains are equipped with state-of-the-art, highly robust technology. They mastered the first 100 days with flying colors, even in wintry conditions and very low temperatures, and are a showcase project for urban mobility. Berlin’s “new one” offers an improved driving experience and greater comfort for Berliners.”
