Should Heathrow Express Be Retired?
With Heathrow’s proposed third runway, traffic and rail capacity are under pressure. Transport experts argue the pricey Heathrow Express may become redundant as the Elizabeth line and other rail projects offer cheaper, more frequent services.

The debate over Heathrow’s airport rail link has intensified as the airport’s £33 billion expansion plan moves forward. The proposal includes a third runway, a new 2.2‑mile runway that will require moving the M25 motorway and will add 100,000 to 200,000 daily passengers. While the airport’s focus has been on expanding flight capacity, the ground transport side is struggling to keep pace.
Why the Heathrow Express Is Under Scrutiny
The Heathrow Express, which charges up to £26 for a 15‑ to 21‑minute journey to Paddington, has long been the fastest link between Heathrow and central London. Yet it carried only 4.5 million passengers last year—less than 6 % of the airport’s total traffic. Much of that traffic comes from airport staff on heavily discounted tickets. The service’s high price and limited frequency have led Transport for London (TfL) to question its viability.
Alex Williams, TfL’s chief customer and strategy officer, told MPs that the Express “takes up valuable paths that aren’t well used” and suggested repurposing the line for a cheaper, more attractive service that could carry more public‑transport users. The current operating agreement with the Department for Transport (DfT) will expire in June 2028, and the Great Western Railway operator is set to be nationalised next year.
The Rise of the Elizabeth Line
The Elizabeth line, which opened in 2022, offers a deeper and cheaper penetration into London’s core. It charges £15.50 to any central London station and runs two trains per hour to Heathrow Terminal 5, which handles about 40 % of the airport’s passengers. While this frequency is set to double next year, the line’s capacity is still limited by the single track that runs into the airport. TfL believes that the Elizabeth line is a more compelling service than the Express, especially for passengers who can plan their journeys in advance.
Other rail options are also on the table. The Piccadilly line, which currently charges £5.90 to central London, is slated for a signalling upgrade that will increase capacity. Two additional rail schemes—Heathrow Southern Railway and a Western Rail link—have been proposed to connect Heathrow more directly to the national network. An extension of the Elizabeth line to Staines could also encourage commuters from the suburbs to use the train instead of driving.
Road Congestion and the Push for Public Transport
Heathrow’s expansion plan includes a significant increase in parking—from 21,000 to 36,000 spaces—and extensive road rerouting. Critics argue that without a clear shift towards public transport, the airport’s expansion could exacerbate traffic congestion. Sadiq Khan, the mayor of London, warned that taxpayers could bear the cost of public‑transport improvements that are “left undefined and unfunded” in the current proposals.
Williams highlighted that the airport’s investment in parking and road infrastructure does not extend to improving train services. He argued that without a strong incentive for passengers to take the train, the expansion could be a “step backwards” from the 2017 commitment to avoid extra traffic.
What’s Next for Heathrow’s Rail Future?
The DfT is reviewing the consultation, which includes public‑transport targets such as 55 % of airport passengers using public transport once the third runway is operational. However, the timeline for achieving these targets is unclear, with the airport’s expansion potentially delaying the third runway until 2039. Transport experts question whether the current rail infrastructure can support the projected passenger growth and whether the Heathrow Express should be retired in favor of more efficient alternatives.
As the debate continues, the future of Heathrow’s rail link will hinge on government policy, infrastructure investment, and the ability to shift passenger behaviour from cars to trains. The outcome will have lasting implications for London’s transport network and the airport’s ability to manage increased traffic safely and sustainably.
Key facts
- Heathrow’s third runway could add 100,000‑200,000 daily passengers
- The Heathrow Express carries less than 6 % of airport traffic
- TfL favors the Elizabeth line for cheaper, more frequent service
- Road expansion plans may worsen congestion if public transport isn’t prioritized
- The airport’s parking expansion could discourage train use
- Future rail capacity is uncertain with the Express contract ending in 2028
Why it matters
The decision to keep or retire the Heathrow Express will shape London’s transport landscape, influencing passenger costs, congestion, and the airport’s environmental impact as it expands to accommodate more flights.
Frequently asked questions
When will the Heathrow Express service end?
Its operating agreement with the Department for Transport expires in June 2028, after which the future of the service remains undecided.
How does the Elizabeth line compare to the Heathrow Express?
The Elizabeth line offers cheaper fares (£15.50) and deeper access into central London, but its current frequency to Terminal 5 is only two trains per hour.
Will the airport’s expansion increase road traffic?
Yes, the airport plans to expand parking from 21,000 to 36,000 spaces and reroute the M25, which could increase road congestion if public transport isn’t adequately improved.
