Over 200 metres long, providing space for up to 1,500 passengers

  • Air-conditioned walk-through carriages, with capacity for 1,500 customers, Wi-Fi and 4G
  • Lightweight and energy efficient design means 30 per cent less electricity use but faster journey times
  • Fully accessible for wheelchair users

A fleet of 66 new 200 metre long trains built in the United Kingdom will run on the Elizabeth line, featuring nine fully-interconnected walk-through carriages, air conditioning, CCTV and real-time travel information. Each train will be able to carry up to 1,500 people.​

In May 2017, Transport for London will begin to introduce a fleet of 66 Class 345 trains built by Bombardier in Derby, helping to support 760 UK jobs and 80 apprenticeships.

Constructed using strong, but lightweight materials such as aluminium for the body shell, the Crossrail trains will be light, yet well equipped for performance and customer comfort with features such as intelligent lighting and temperature control systems.

The trains will regenerate electricity back into the power supply when braking to use up to 30 per cent less energy, as well as delivering faster journey times than the old trains.

Large, clear areas around the doors will allow quicker and easier boarding and alighting. A mixture of metro-style and bay seating will be available through the train, providing choice and comfort for customers. The trains will be driver-operated with on-train customer information systems delivering real-time travel information, allowing customers to plan their onward journeys whilst onboard. Free Wi-Fi will be available on the trains as well as on the platforms and people will have access to 4G.

The interior design and colour palette has been carefully selected to provide an accessible and welcoming environment. The design includes darker floors and natural finish materials that will wear in, and not wear out, ensuring they retain their high-quality feel for years to come. The light coloured ceilings also maximise the feeling of height and openness inside the new trains. The material and colour choices also align with Crossrail stations for a consistent customer experience.

There will be four dedicated wheelchair spaces on each train. In addition, there will be a number of multi-use spaces available, where seating can be tipped up to accommodate prams or luggage.

Opening the Elizabeth line

The current planning assumption is that new trains will be introduced to run services as follows:

  • May 2017: The first new train enters passenger service between Liverpool Street Main Line and Shenfield.
  • May 2018: TfL Rail service opens between Paddington (National Rail) and Heathrow Terminal 4, replacing the existing Heathrow Connect service and part of the Great Western inner suburban service.
  • December 2018: The Elizabeth line opens between Paddington and Abbey Wood, Liverpool Street to Shenfield, Paddington Main Line to Heathrow Terminal 4.
  • May 2019: The Elizabeth line through service extends from Shenfield to Paddington.
  • December 2019: The Elizabeth line is fully open, extending to Reading and Heathrow Terminal 4.


  • Central section – Paddington to Whitechapel: At peak times, 24 trains in each direction will run through central London between Paddington and Whitechapel.
  • South eastern branch - Canary Wharf to Abbey Wood: At peak times, 12 trains an hour in each direction will link southeast London and the Docklands to central London. 
  • Eastern surface section - Shenfield to Stratford: At peak times, 12 trains an hour will run between Shenfield and central London, calling at all stations. An additional four trains an hour will run between Gidea Park and the existing Liverpool Street station, westwards in the morning peak and eastwards in the evening peak.
  • Western surface section - Reading to Acton Main Line: At peak times, two Elizabeth line trains will start at Reading. These will be joined by two further trains at Maidenhead, two at West Drayton and four from Heathrow. Surface stations in west London from Hayes & Harlington inwards will be served by 10 trains an hour in each direction.
