The extension of the HS2 rail line to London Euston is contingent upon securing enough private investment for the project. Without private funds, the high-speed line will only run from Birmingham to Old Oak Common in the western suburbs of London. This would require passengers traveling to central London to change trains. The government has acknowledged the need for private investment and aims to learn from successful examples of private sector involvement in other schemes, such as the redevelopment of Battersea Power Station and King’s Cross station. However, critics argue that the new plans are unambitious and have raised concerns about the lack of options for onward journeys from Old Oak Common. The Department for Transport (DfT) is determined to open Euston station as soon as possible and believes that its revised approach will save £6.5 billion. The DfT has already received support and interest from the private sector and intends to ensure that funding is underpinned by contributions from those who will benefit from the development. Nevertheless, critics have questioned the change in stance and called for accountability for the mistakes and mismanagement of the project.
