DB requires the IS 600 maintenance checks to be carried out once a high-speed train has operated for 1.65 million km.
Work will be carried out from the middle of 2021 in the “expert house” service area of the Siemens Mobility Test and Validation Centre in Wegberg-Wildenrath, North Rhine-Westphalia.
As part of the IS 600 revision, Siemens Mobility will inspect the central systems and components of the ICE 4 trains and carry out planned maintenance activities. This includes the doors, windscreen washer systems, couplings, running and traction bogies, as well as pantographs, train control systems, and brakes.
Work on the interiors will include maintenance of fire alarm systems, passenger information systems, and catering and sanitary facilities. The wheelsets will also be exchanged on all trains.
DB has ordered 137 ICE 4 trains from Siemens Mobility since May 2011. The first trains in the series entered passenger service in 2016 and Siemens has delivered 65 trains as of December, with a new ICE 4 train currently joining DB’s mainline fleet every three weeks.
