Western section - Paddington to Heathrow and Reading

The western section of the Elizabeth line route will run on the existing rail network from Paddington to Heathrow and Reading.

A number of major upgrades are being carried out by Network Rail on this section of the route in preparation for the arrival of Elizabeth line services. The Crossrail project will provide new trains, better stations and easier, more reliable journeys for passengers in west London, South Bucks and Berkshire.

Better stations

Major improvements are being delivered to stations across the western section of the route, including:

  • New, bright, spacious ticket halls at a number of stations in west London
  • New lifts and footbridges where required to ensure step free access at every station
  • Platform extensions to accommodate the 200m long Crossrail trains
  • New signage, help points, customer information screens and CCTV.

Track and infrastructure upgrades

Major upgrades are being delivered to improve reliability.

  • A new flyover has been built at Stockley to add capacity at the busy junction to Heathrow
  • A new dive-under has been built in Acton to remove a bottleneck to the west of Paddington
  • The electrification of the railway in west London, South Bucks and Berkshire to pave the way for the introduction of quicker, greener, more reliable electric trains
  • A new depot at Old Oak Common
  • Sidings at Maidenhead

The Elizabeth line service on the western section

Transport for London (TfL) took over responsibility for stopping services between Heathrow and Paddington Main line station in May 2018 in preparation for the arrival of full Elizabeth line services.
