Rail
At Western Gateway STB, we collaborate with local authorities and partners like Network Rail, Great Western Railway, South Western Railway, CrossCountry and Great British Railways to deliver an integrated and effective rail service for everyone in our region and beyond.
2020 Rail strategy
Our Rail Strategy, published in 2020, outlines a clear vision across five key themes to improve rail – choice, decarbonisation, social mobility, productivity, and growth – supported by focused objectives, the regional priorities and actions.

Our projects
It’s full steam ahead to deliver following exciting projects:
Westbury Platform 0
Westbury Platform 0 Moves a Step Closer
Westbury Platform 0, which has been disused since 1984 due to the removal of the track, is set to return with development funding from the Western Gateway and Wiltshire Council.
Timetable analysis shows that a reinstated Platform 0, together with targeted infrastructure improvements such as a loop on the Melksham line, could support:
- More frequent passenger services to Westbury, Swindon, Weymouth and Exeter
- Additional freight services across the network
- Progress towards hourly Heart of Wessex Line services
- Improved connectivity for the proposed Devizes Gateway station
- Enhanced capacity for a potential Paddington to Westbury service extension
The study also identified wider rail network enhancements that would be needed to unlock further passenger and freight growth, including upgrades west of Castle Cary and on the Berks & Hants line.
Beyond increased capacity, Platform 0 would deliver significant benefits for network resilience, reliability and performance, supporting rail services connecting London, Bristol, Gloucester, Salisbury and Exeter.

Dorset Metro
We’ve been exploring, jointly funded with Dorset Council, options for additional rail services between Wareham and Brockenhurst, including an ‘all stations’ calling service and/or a
‘limited stops’ service. Network Rail has identified key infrastructure upgrades needed to make these service increases, including:
·Reduced headways and junction margins at Brockenhurst
· New platforms, track, and footbridge works at Bournemouth
· Double tracking at Weymouth and between Moreton and Dorchester
The Strategic Outline Business Case (SOBC) has been produced with the final draft now available.

While the benefit cost ratio (value for money) of the Dorset Metro has come out disappointingly low this work should be viewed as a starting point and interim position. There is still great potential in the Dorset Metro proposals and it is proposed to take a multi modal corridor approach. This will capture all the benefits that an integrated public transport system could offer. Previous study work including Local Plans, the joint Dorset and Bournemouth, Christchurch & Poole Local Transport Plan and interlinked projects including the rural mobility pilots, Heart of Wessex Line proposals, Bus Service Improvement Plan schemes, integrated ticketing, park and ride and the Western Gateway Strategic Cycle Network and Coach Strategy will be brought in.

West of England Line (Tisbury Loop)
Funded by the Western Gateway the Strategic Outline Business Case for half hourly services on the West of England Line between Salisbury and Yeovil has been finalised by Network Rail. There have been long standing aspirations to improve the service on this line which is currently hourly and this was one of the recommendations in Network Rails West of England Line Continuous Modular Strategic Plan in 2020. The line also suffers from significant capacity and performance constraints.
Early work identified an extended passing loop at Tisbury, a critical bottleneck on the single track section, would provide the capacity to run additional services and improve the performance and resilience of the line. Several loop options have been explored. Unfortunately all options had a low benefit cost ratio (value for money) with upfront capital costs of between £31.5m to £88.6m and train operating costs outweighing the journey time benefits generated by the proposals.
More work on the performance benefits of the loop is being undertaken by Network Rail and the impact a loop extension could have to mitigate service level reduction caused by the Soil Moisture Deficit issue on the line. So our work is very much an interim position and a first step toward a more reliable, accessible, and flexible West of England Line.
We welcome the invitation to join the new West of England Line Stakeholder Advisory Board. This is a new group set up by South Western Railway to help advise and support the rail industry in developing and promoting the plan to modernise the West of England line between Exeter and London Waterloo over the next 10-20 years.

Bristol to Oxford line
A quick and cost-effective opportunity existed to reinstate direct rail services between Oxford, Swindon, Bath, and Bristol. And now it is in operation. Building on the successful Saturday trial, this new hourly, all-day service cuts journey times to under 1 hour 15 minutes between Oxford and Bristol and just over 30 minutes to Swindon.
This service strengthens links between industries, universities, and tourist destinations while maximizing the impact of major investments like East West Rail and MetroWest.
We published the Case for Change brochure for the Bristol – Swindon – Oxford service, which was produced in collaboration with our fellow STB, England’s Economic Heartland STB, and Network Rail.

Heart of Wessex Line
Network Rail have investigated the potential to explore the current state of rail provision along the Heart of Wessex Line, considering the markets it serves and the potential opportunities that an enhanced 1tph service could provide along the line between Bristol and Weymouth.

Our rail focused groups
Rail Officer Group (ROG)
The Rail Officer Group meets monthly to provide updates on the Western Gateway’s rail programme to officers from our nine local authorities and get their input. Wider rail issues are discussed, which includes creating joint responses to rail industry consultations.
Community Rail Partnership
We host bi-monthly meetings with six Community Rail Partnerships in the region. We value their innovative work on encouraging rail use for everyone. Our meetings are two way with updates provided on the work of the Western Gateway and the Partnerships updating on their activities. With so much happening on rail, we’re moving the frequency of meetings to every two months.

Cheltenham Spa
Arising from the recommended interventions from the Bristol to Birmingham Strategic Rail Study, the Western Gateway funded feasibility work on a new south facing platform at Cheltenham Spa station. The new platform brought performance, capacity and resilience benefits for the station but did flag up wider network issues. Work has been on hold whilst Network Rail’s Gloucestershire Rail Review gets underway.

Future work
- Westbury Platform 0 economic feasibility
- Case for Change document bringing together all our rail projects
- Heart of Wessex Line refresh and advocacy for investment
- Bath Wiltshire Metro – support ongoing development
- Poole Area Strategic Study – support Network Rail work
