The redevelopment of Cardiff Central station is set to begin after an agreement was reached to commit £40 million to the project.
The Cardiff Capital Region has agreed in principle to provide £40 million to the scheme from its £1.28 billion City Deal Investment Fund.
The money will be provided on the basis that £40 million will also be put forward by the Welsh Government, £40 million from the private sector, with the remainder coming from the UK Department for Transport.
Phase two of the Metro Central Project, which is estimated to cost £160-180 million, includes upgrading Cardiff Central.
Officials say the project will benefit the entire region, particularly when faster, more frequent services are delivered through the creation of a South Wales Metro.
Graphics illustrating the Metro Central Project development also appear to show the station served by a new light rail system.
The leader of Cardiff Council, Councilllor Huw Thomas, said: “We are working on a plan which could see 30,000 more jobs brought to the capital all based around or near to Central Station.
“For our plan to succeed we need to improve the capacity of the Central Interchange to accommodate the amount of people who will be travelling to the city centre to take up those jobs. Whether they come by bus, by train, cycle, walk or by car we need to get the infrastructure right.”
