Knorr-Bremse wins door systems contract for London new Tube trains

door systemsSiemens Mobility awarded Knorr-Bremse subsidiary IFE a contract for the supply of 3,760 door systems for 94 London Underground trains. The contract also includes an option for 9,000 additional door systems for a further 216 Tube trains by 2030.

The systems comprise 3,760 door drives and 7,144 door leaves which will be installed on the 94 nine-car Inspiro trains. The new trains will enter services on the Piccadilly line served by 53 stations with a total length of 70 km starting 2024.

The most challenging aspects of the Piccadilly line upgrade project include the unusually pronounced curvature of the door leaves that allows them to fit inside the narrow, tube-shaped tunnels combined with tight deadlines.

Although the external sliding doors and spindle drives feature an individual design tailored to the customer’s specifications, they also use tried-and-tested components.

To maximise the UK content and service provision, IFE will work closely with Siemens Mobility. The company will continue to expand its services and local footprint, particularly in the Greater London area, to support the introduction and smooth running of the door systems on the new train fleet. This will support Siemens Mobility and Transport for London’s ambitions to create significant numbers of UK jobs aligned to the Deep Tube Upgrade Programme, which includes the development of Goole facility, the new Siemens Mobility rail manufacturing site in the UK.

The entrance systems will help to meet passengers’ “growing mobility requirements and helping to deliver faster, more frequent and more reliable journeys,” Jürgen Wilder, Member of the Executive Board of Knorr-Bremse AG said.

This is Knorr-Bremse’s first contract to supply doors for Tube’s trains, but for London’s rail system, the company has delivered entrance systems for LRVs, regional multiple units and high-speed trains.

In 2018 London Underground awarded Siemens Mobility a EUR 1.54 billion contract for the supply of 94 new trains which will replace the existing 1970s fleet.
