Transport for London (TfL) has announced it will award Siemens a contract of around £1.5bn to design and build 94 new generation Tube trains for the Piccadilly line customers.

The order is the first for the deep Tube upgrade programme involving four lines - the Bakerloo, Central, Waterloo & City and Piccadilly - and will involve the replacement of the entire 1970s Piccadilly Line fleet.

The new trains will have a host of new design features that will significantly increase customer comfort. Each new train will be six metres longer than the existing Piccadilly line trains. They will include walk-through, fully air conditioned carriages and improved accessibility, and will be specially designed to optimise the space constraints in the narrow Deep Tube tunnels. Customers will also benefit from in-train information systems helping them to plan their onward journey more easily.

By the end of 2026, there will be 27 trains-per-hour to operating at peak times on the Piccadilly line, up from the current service level of 24 tph. This equates to a train every 135 seconds at the busiest times. Combined with a signalling upgrade and the purchase of additional trains, peak period capacity will allow for an additional 21,000 customers to board trains every hour during peak times.

More than 700,000 customers use the Piccadilly line every day. However, the combination of limited fleet size and old signalling technology has restricted TfL’s ability to increase capacity across the line for many decades.

This long-term sustainable investment will support London’s growing population which is set to increase to 10.8 million by 2041, supporting new jobs, homes and growth, benefiting the whole UK economy with the build of a new factory in Goole, East Yorkshire

The new Siemens Mobility factory would employ up to 700 people in skilled engineering and manufacturing roles, plus up to an additional 250 people during the construction phase of the factory. As a result, around 1,700 indirect jobs would be created throughout the UK supply chain.

The four Deep Tube lines make up a third of the Underground network, carrying around two million passengers per day on key corridors linking the City, the West End, King’s Cross and Heathrow Airport.
