Greater Anglia, which runs trains across Suffolk - as well as Norfolk, Essex, Cambridgeshire, and Hertfordshire, will return to public ownership this weekend.
The firm says passengers should see no immediate changes when the transition takes place next week.
The operator has been the best-performing train company in the UK for the past two years, achieving 94.1% punctuality across its routes in the 12 months to 31 March 2025.
Jonathan Denby, head of corporate affairs for Greater Anglia, said the company remains “absolutely focused” on running a reliable and high-quality service for passengers and stakeholders.
Mr Denby, who began his rail career with British Rail in 1990, said the team’s task is to continue “running a really good railway for passengers and stakeholders who depend upon us.”
The government has described Greater Anglia as a “blueprint for publicly-owned rail,” saying it will share its expertise across the national network once re-nationalised.
It’s part of a wider plan to bring more train services in Britain under public ownership — a move ministers say could save up to £150 million and help tackle delays and cancellations.
Greater Anglia operates routes across the East of England and into London, including the Stansted Express airport service.
