Siemens Mobility has secured a new maintenance contract from Deutsche Bahn (DB) to perform IS 600 revision on 40 Series 412 ICE 4 trains.

Marking the largest service order ever awarded to Siemens Mobility by Deutsche Bahn, the contract also includes an option for the revision of 50 additional trains of the same model.

The new high-speed trains need to undergo IS 600 maintenance revisions after operating for 1.65 million kilometres.

Siemens Mobility CEO Johannes Emmelheinz said: “The ICE 4 is the backbone of DB’s mainline rail operations.

“As DB’s service partner, we will make a decisive contribution towards guaranteeing the availability and operation of the ICE 4 fleet and ensuring its sustainable performance over the entire lifecycle.”

The maintenance works will be carried out in the ‘Expert House’ service area of the Siemens Mobility Test and Validation Center in Wegberg-Wildenrath, North Rhine-Westphalia, starting from the middle of the year.

As part of the IS 600 revision, Siemens Mobility will test the central systems and other components of the ICE 4 trains, as well as carry out planned maintenance activities.

The scope of work will include maintenance of the doors, windscreen washer systems, couplings, running and traction bogies, as well as pantographs, train control systems, and brakes.

The company will also work on the interiors for the maintenance of fire alarm systems, passenger information systems, bistro equipment and the sanitary facilities.

The wheelsets will also be exchanged on all vehicles.

Since May 2011, DB has ordered a total of 137 ICE 4 trains from Siemens Mobility, which had delivered 65 units by last December.

Earlier this month, Siemens Mobility signed an MoU with Egypt’s National Authority for Tunnels and other local firms to deliver a high-speed rail transportation system.
