Alliance Rail Clashes with Network Rail Over Waterside Line Plans

Alliance Rail has accused Network Rail (NR) of consistently obstructing its proposal to introduce open access services between Marchwood, Southampton and London Waterloo, claiming the infrastructure operator is “abusing its position” during the approval process.

The application, submitted to the Office of Rail and Road (ORR) in late 2024, remains under review, with both Network Rail and the Department for Transport (DfT) raising concerns about its impact.

Network Rail has argued that the proposed services could place strain on the already busy South Western Main Line. Of 33 potential train paths assessed, it said a number would significantly affect the timetable, while others would still present moderate challenges. Concerns were also raised about whether Alliance Rail’s Class 769 trains could match the performance of existing South Western Railway (SWR) services.

However, Alliance Rail says those concerns have been addressed, noting that its Class 769 bi-mode trains have now been certified to operate at speeds of up to 100mph, which it believes removes doubts about compatibility with existing services.

Performance on the route remains a key issue. Network Rail highlighted that several sections, particularly between Waterloo and Woking, already experience reduced punctuality, with closely timed services affecting overall reliability. It warned that introducing additional trains could exacerbate these issues, including around Southampton Central.

Alliance Rail’s Managing Director, Ian Yeowart, rejected these claims, stating that a compliant timetable has already been developed in collaboration with Network Rail planners, demonstrating that capacity exists. He argued that the performance of other operators should not be used as a reason to block new services, particularly those aimed at improving connectivity.

The proposal includes a two-hourly service to London and the reopening of Marchwood station, which has been closed to passengers since 1966. While the DfT has indicated the plans meet regulatory thresholds for new services, it has raised questions over funding responsibilities for station upgrades and level crossing improvements.

Alliance Rail insists these costs have been accounted for and argues that private investment should be welcomed, particularly for projects previously supported by public sector initiatives.

If approved, the service would use refurbished Class 769 trains, which are currently in storage and awaiting testing. The operator is hoping for a decision from the ORR in the coming months as discussions continue over the future of the scheme.
