Plans to introduce new passenger services between London and Wrexham, Rochdale and Blackpool have been rejected by the Office of Rail and Road (ORR), with the regulator warning that additional trains on the West Coast Main Line could worsen reliability and increase disruption for existing passengers.
The decision follows an extensive assessment of available capacity on the southern section of the West Coast Main Line (WCML), one of Britain’s busiest and most strategically important railway corridors.
ORR concluded that the infrastructure remains under significant pressure and that introducing further services into an already congested timetable would reduce the network’s ability to recover from delays, increasing the likelihood of disruption spreading between operators.
The decision affects applications from prospective open access operators Wrexham, Shropshire & Midlands Railway Company (WSMR) and Lumo, alongside proposals from Avanti West Coast to increase its services between Blackpool and London Euston.
New Wrexham and Rochdale services refused
WSMR had sought approval to operate four return services each day between Wrexham and London Euston, while Lumo proposed up to four return services between Rochdale and Euston.
Both applications have been rejected.
ORR has also refused Avanti West Coast’s application to introduce additional services between Blackpool and London.
The decisions follow similar refusals in 2025, with the regulator finding that the capacity and performance constraints affecting the southern WCML have not materially improved in the intervening period.
An independent external review commissioned by ORR supported that conclusion.
While new services could improve connectivity and increase passenger choice, the regulator determined that the potential benefits would be outweighed by the risks to the reliability of the wider network.
The outcome represents a setback for ambitions to expand direct London services to communities in North Wales and northern England, particularly where operators have sought to introduce new connections through open access arrangements.
Timetable recovery margins critical to reliability
A central issue in ORR’s assessment was the importance of protecting recovery time within the existing timetable.
Although gaps between scheduled trains may appear to represent unused capacity, they play an essential role in allowing the railway to recover when services are delayed or infrastructure problems occur.
On heavily used routes such as the WCML, these margins help prevent individual incidents from escalating into wider disruption affecting multiple services.
ORR concluded that inserting additional trains into those gaps would reduce operational flexibility, leaving less opportunity to recover from disruption and increasing the likelihood of delays spreading across the network.
The decision highlights the distinction between theoretical timetable capacity and the practical ability to operate additional services reliably.
For operators and infrastructure planners, it reinforces the importance of assessing not only whether extra train paths can be accommodated, but also their impact on the performance and resilience of the wider timetable.
Stephanie Tobyn, ORR’s Director of Strategy, Policy and Reform, said: “New services, destinations and greater choice can bring real benefits for passengers and communities. But the West Coast Main Line is already under significant pressure, with performance reflecting limited resilience on a heavily used part of the rail network.
“Our detailed analysis has shown that adding more trains to the current timetable would reduce the ability to recover when disruption occurs, increasing the risk of delays spreading and making reliability of the network worse for all passengers.”
Avanti Chester service receives approval
Although the regulator rejected the proposed additional services, it has approved a separate application from Avanti West Coast that will allow passengers to use an existing train movement.
Avanti’s weekday 19:29 Chester to London Euston service has been granted passenger access rights until December 2030.
The train already operates as a fully crewed empty service, meaning the approval will not introduce an additional train onto the network.
Instead, the existing movement will be available to passengers, increasing travel opportunities without adding further pressure to infrastructure capacity.
The decision demonstrates the regulator’s willingness to support additional passenger services where they can be accommodated without increasing the number of trains using the constrained route.
It also highlights the potential for operators to make more effective use of existing train movements as capacity becomes increasingly difficult to secure on heavily used parts of the network.
Capacity constraints present wider challenge for rail growth
The refusal of the applications raises broader questions about how Britain’s railway can accommodate ambitions for additional passenger services while maintaining acceptable levels of performance.
The southern WCML carries a complex mix of long-distance, regional, commuter and freight traffic, with different stopping patterns and operating requirements competing for limited infrastructure capacity.
Introducing new services into that environment requires careful consideration of the consequences for existing operations, particularly when recovery margins are already constrained.
The decision also underlines the challenge facing open access operators seeking to establish new routes on heavily used main lines.
Although open access can provide additional destinations, competition and passenger choice, operators must demonstrate that proposed services can operate within the practical limitations of the network.
For the wider industry, the issue is not simply whether demand exists for new services, but whether the infrastructure and timetable can support that demand without compromising reliability.
West Coast decision highlights importance of future capacity
The findings also reinforce the longer-term significance of capacity investment on the West Coast corridor.
One of the principal objectives of HS2 is to release capacity on the existing West Coast Main Line, particularly on its heavily used southern approaches to London, creating opportunities for additional passenger and freight services.
However, with significant work remaining on the new high-speed railway, the existing network must continue to balance aspirations for growth against the operational realities of constrained infrastructure.
In the meantime, ORR’s decision makes clear that protecting timetable resilience will remain a priority when assessing applications for additional services.
For train operators, prospective entrants and the rail supply chain, the message is that expanding rail connectivity cannot be considered independently of network performance.
The rejection of the Wrexham, Rochdale and Blackpool proposals illustrates the difficult choices involved in managing a railway where demand for additional services is competing with the need to protect reliability for passengers already using the network.
