Background and reasons for application
Through this application, GC is seeking to introduce new open access services between London
Waterloo and Bristol Temple Meads via the SWML , Salisbury and the Wessex Main Line, providing both new connectivity and increased competition on long distance flows with the intention of attracting new demand to rail.
The proposal responds to both changes in the rail offering following post pandemic timetable
adjustments and existing constraints in network capacity. The Great Western Main Line (GWML) is the principal route between London and Bristol but is increasingly capacity constrained and subject to multiple live and accepted open access applications. In contrast, the SWML and associated routes present an opportunity to make effective use of available capacity to introduce a new long distance service, avoiding the most constrained parts of the network.
Prior to 2021, passengers travelling to and from stations on the proposed route benefited from direct services to London Waterloo; however, these services were withdrawn as part of post‑pandemic timetable changes, reducing connectivity and removing this alternative route to London. The proposed services will restore these connections while also providing improved journey opportunities on core sections of the route, including enhanced links between London and Salisbury.
At the same time, the current market offering between London and Bristol is focused primarily on a single congested corridor using the GWML, resulting in limited effective competition for a number of flows, particularly for price sensitive and discretionary passengers as well as where rail is not currently considered as an option. The proposed GC service introduces a differentiated, value focused alternative, providing an additional travel option, increasing competition. This includes targeting under-served stations along the route, including Warminster, Westbury, Trowbridge and Bradford on Avon. GC will additionally explore extending services to Portishead, with the restored railway targeted to open from 2028. These locations have limited to no direct long distance connectivity and are well aligned to GC’s established approach of developing and growing demand in underserved markets through the introduction of new direct journey opportunities and competitive fares.
Services and operation
GC is seeking to operate up to seven full return services per weekday and six full return services per day on a Sunday between London Waterloo and Bristol Temple Meads. Services would call at Clapham Junction, Salisbury, Warminster, Westbury, Trowbridge, Bradford on Avon, Bath Spa and Bristol Temple Meads.
The proposed timetable has been developed based on the May 2026 timetable and is designed to make efficient use of available capacity on the SWML and connecting routes, with only limited adjustments required to existing services. GC has undertaken timetable and capacity analysis which demonstrates that the proposed services can be accommodated within current infrastructure capability, subject to normal industry processes and performance assurance.
The service will be operated using 100mph capable rolling stock. GC intends to secure appropriate off lease rolling stock for the operation of the services and will undertake the necessary investment to prepare the fleet for entry into service. Stabling is proposed at Arriva TrainCare Eastleigh, with additional facilities at Bristol to support efficient operation of the timetable.
The proposed calling pattern has been designed to balance long distance journey opportunities with the provision of improved connectivity for intermediate stations, restoring direct links toLondon while integrating with existing regional services. In particular, the inclusion of Clapham Junction enables a wide range of interchange opportunities, strengthening connectivity between the South West, South London and the wider South East.
Access rights sought
Under this application, GC is seeking firm access rights under a new Track Access Contract for up to eight return services per day between London Waterloo and Bristol Temple Meads. This application is made under Section 17 of the Railways Act 1993. GC will continue to work collaboratively with Network Rail and industry stakeholders throughout the consultation process to refine the proposal and demonstrate that capacity and performance impacts are acceptable in the context of the benefits delivered.
