Introduction
Alstom has begun building the first of ten new Elizabeth line trains at its Derby factory, a project backed by over GBP 220 million in UK Government investment. These new trains will increase capacity on London’s busiest railway, which currently carries around 800,000 passengers daily.
Production and Investment
The construction of the new trains at Alstom’s Derby factory supports over 1,000 jobs and nearly 40 companies within the UK supply chain. The GBP 220 million investment from the UK Government funds the additional Aventra Class 345 units. The Elizabeth line opened in 2022 and has since become the most-used rail service in the country.
Impact and Capacity
The Elizabeth line is set to serve HS2’s Old Oak Common station in the future. Transport for London (TfL) has stated that its supply chain activity supports over 3,000 UK suppliers. This generates GBP 11 billion in gross value added and around 100,000 full-time jobs each year. An evaluation report highlights the railway’s impact on travel, housing, and employment. Since its opening, it is estimated that 71,000 additional trips are made each weekday across London’s transport network.
Accessibility and Journey Time Improvements
The Elizabeth line has achieved an 11 per cent reduction in average step-free journey times. Every station between Paddington and Woolwich offers step-free access. Journey times between Canary Wharf and Abbey Wood have decreased, with trips from Abbey Wood to key employment hubs now 20–40 minutes faster. Approximately 16 per cent of trips starting in Abbey Wood on public transport would not have occurred without the line.
Development and Economic Growth
As of October 2024, 70,500 homes have planning permission within 1 km of Elizabeth line stations, with the largest clusters at Canary Wharf, Stratford, Romford, Southall, and Acton Main Line. Between 2022 and 2023, 125,000 new jobs were registered within the same radius. The proposed Docklands Light Railway (DLR) extension from Beckton Riverside to Thamesmead could potentially deliver 25,000 homes and 10,000 jobs if funded.
Conclusion
The construction of new trains at Alstom’s Derby factory, supported by UK Government investment, aims to increase capacity on the Elizabeth line. The project is expected to boost employment, reduce journey times, and drive economic growth across London and the UK.
