Grand Union

Grand Union is a prospective open access operator who are proposing to operate train services in the United Kingdom from London to Wales and Scotland. Grand Union is headed by Ian Yeowart, who founded previous open access operators Alliance Rail Holdings and Grand Central before selling both to Arriva.

London - Wales
Grand Union is proposing to operate two-hourly services between London Paddington and Cardiff Central calling at, Bristol Parkway, Severn Tunnel Junction, Newport and Cardiff Parkway. From 2023, the service would be increased to hourly and extended to Llanelli calling at: Swansea and Llanelli, with possibly a further extension to Carmarthen. In its April 2019 submission to the Office of Rail & Road, it proposed operating hourly services between London Paddington and Cardiff Central. In July 2019, the application was withdrawn and replaced with an amended one.

Grand Union proposes to operate InterCity 225s initially but later plans to use Class 802s if the service is increased to hourly and extended.

London - Scotland
In August 2019, Grand Union lodged an application to operate four trains each way per day between London Euston and Stirling calling at Milton Keynes Central, Nuneaton, Crewe, Preston, Carlisle, Lockerbie, Motherwell, Whifflet, Greenfaulds and Larbert with InterCity 225s from May 2021.
