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.
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.
Both of these structures were brought into use at the beginning of January 2017.
Other upgrades include:
- 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 improvement works will at times affect journeys at weekends and over bank holidays. Passengers can check before they travel on the National Rail Enquiries website.
The Elizabeth line service on the western section
Transport for London will take over responsibility for stopping services between Heathrow and Paddington Main Line station from May 2018 and the route will open in full in December 2019.
