Siemens Mobility and the UK’s Transport for London (TfL) have revealed the detailed design of the new Piccadilly line Tube trains, which will soon be produced to replace the current 1970s fleet.

The existing trains, which will be 50 years old by the time of their replacement, have become unreliable and costly to maintain.

The new ‘Inspiro London’ trains are expected to commence operations from 2025 on the Piccadilly line.

With the introduction of the new trains, the existing fleet will be gradually withdrawn from passenger service.

During peak hours, the frequency of trains also will increase from 24 to 27 trains an hour from mid-2027, representing a 23% rise in capacity.

The new trains will feature optimised spacing, wider doors and longer, air-conditioned walk-through carriages.

The innovative articulated designs will be lighter, increase energy efficiency and reduce track damages.

With a 95% recoverability rate, the new trains will offer regenerative braking capability, modern traction systems, LED lighting, and cutting-edge energy management.

In comparison with the current fleet, energy consumption will also be reduced by 20%.

The design of the new fleet has been developed on the basis of the feedback received from TfL’s Independent Disability Advisory Group (IDAG) and the TfL Accessibility Forum.

Around 50% of the new trains will be produced in Goole, East Yorkshire.

Siemens Mobility CEO William Wilson said: “The state-of-the-art trains will transform the Piccadilly line passenger experience. They are lighter, more environmentally-friendly and future-proofed for a long life. But the benefits are not just confined to London.

“Building the new trains creates new UK jobs and extensive supply chain opportunities.”

Last month, the company announced £50m of associated contracts for UK suppliers for train components.

Nearly £6m in contracts were secured by I M Kelly for driver seats and footrests, LPA Lighting to supply the interior train lighting, and Baker Bellfield to provide cab partition wall.

The company stated that this project will generate around 25,000 new job opportunities in London.
