Plans for a huge expansion of the West Midlands' metro and rail services have been suggested, which would create a London Underground style transport network.
The plans have been put forward by West Midlands Mayor, Andy Street, as part of his re-election campaign.
What is it?
The network would cost £15billion and take 20 years to complete.
150 miles long
380 new stops
Eight new Metro lines
21 new rail stations
How would it be paid for?
Coming in at £15billion, or around £750 million per year for the next 20 years, Andy Street claims the costs would be met by more funding from central Government, contributions from housing and commercial developers and borrowing against the future income from ticket sales on the Metro.
Where will the stations be?
The 21 new stations would include re-opening the Sutton Park Line, starting with Aldridge station, re-opening Pelsall and Brownhills stations, and building a new station at Tettenhall.
New Birmingham stations would also be created in Balsall Heath and Dudley Road.
New technology such as driverless pods would be used in Coventry to connect key sites such as the University of Warwick, Jaguar Land Rover, Ansty and the City Centre.
Four new stations would also be added in Coventry at Coundon Road, Foleshill, Coventry South and Binley/Willenhall.
Plans to re-open the Camp Hill line and the Walsall to Wolverhampton line are at planning stage already.
The lines will be named after prominent West Midlands figures, such as the politician and former mayor of Birmingham, Joseph Chamberlain and the MacArthur line named after Mary MacArthur - the women's trade unionist.
The Lee Woods line honours the famous mathematician and scientist, Mary Lee Woods and the Zephaniah line is named after the poet Benjamin Zephaniah.
Andy Street says he doesn’t want the area to be left behind.
It follows years of work in Birmingham City Centre to extend the existing tram network.
