IC5

The DSB Class ES is a planned electric multiple unit train class ordered by the Danish State Railways, branded as IC5 and part of Alstom's Coradia Stream family, built by Alstom in Poland and Germany. It is intended to replace several older DSB train types, including the IC3, IC4, IR4 and Class ET Øresundståg trainsets, supporting DSB's transition from diesel-powered rolling stock to a fully electric fleet. On 12 April 2021 DSB announced that it would acquire 100 trains from Alstom, an investment of 2.6 billion euros including 15 years of maintenance, the largest in DSB's history. On 12 May 2021 Stadler Rail filed a complaint against the contract award, and the contract was signed in June 2021. The IC5 name was announced in April 2022, and entry into service was delayed from December 2024 to mid-2025 and, in November 2023, to 2027. Testing began at Velim in the Czech Republic on 1 September 2024, where test trains reached 200 km/h, and in June 2025 DSB ordered 50 additional trainsets, bringing the combined order to 153. The first trainset arrived in Denmark in September 2025 and series production began in February 2026.
