Tokyo Metro, as part of joint venture GTS Rail Operations, commenced as operator of the Elizabeth Line in London on 25th May, 2025

　Tokyo Metro Co., Ltd. (Head Office: Taito-ku, Tokyo; President and CEO: Akiyoshi Yamamura; hereinafter "Tokyo Metro") , as part of joint venture GTS Rail Operations limited (Ownership: Go-Ahead 65%, Tokyo Metro 17.5%, Sumitomo Corporation 17.5%; hereinafter "GTS"), commenced as operator of the Elizabeth line on behalf of Transport for London (TfL)*, in London, United Kingdom, on Sunday, May 25, 2025. This is being undertaken in partnership with The Go-Ahead Group Limited (Head Office: Newcastle, United Kingdom; hereinafter "Go-Ahead"), the operator of the UK's largest railway network, and Sumitomo Corporation (Head Office: Chiyoda-ku, Tokyo; Representative Director, President and CEO: Shingo Ueno; hereinafter "Sumitomo Corporation"). The contract period is up to 9 years (a 7-year base term plus an optional extension period of up to approximately 2 years).

　After being awarded the operating contract in November 2024, GTS has signed an operating agreement with TfL and has since been working on a smooth transition from the previous operator who has been running services since the Elizabeth line opened in 2022.

　With the launch of this project, Tokyo Metro has assigned one director to the GTS board to participate in its management and also has sent two employees to the UK to join GTS. Additionally, Tokyo Metro plans to support GTS with a committee based in its Head Office in Japan, comprised of relevant executive officers and directors to ensure close coordination between the local UK operations and Tokyo Head Office for the project's success.

　While continually collaborating with TfL and other stakeholders, Tokyo Metro is co-operating with Go-Ahead and Sumitomo Corporation to further support the high-quality railway operations on the Elizabeth line, utilising 100 years of expertise in safe and punctual railway operations.

　This marks Tokyo Metro's first involvement in operating an overseas railway business. Moving forward, the company will strive to expand its participation in overseas railway business, including O&M (operation and maintenance) business, with the aim of generating revenue and contributing to the development of urban transportation systems in cities around the world.
