Plans have been made to build a "crowded" station to meet growing demand.
The Birmingham University Station was designed to open in the 1970s for 400,000 passengers a year.
But the growth of the University of Birmingham and the nearby Queen Elizabeth Hospital has served 3.3 million people.
Those behind the plans hoped that this would create better conditions for rail users.
The new proposals to be completed in time for the 2022 Commonwealth Games in the city are expected to accommodate 7.2 million people each year.
The plans are led by Transport for West Midlands and must be funded by a consortium including the Ministry of Transportation, Network Rail, the West Midlands Railways, Greater Birmingham and Solihull Local Enterprise Partnerships, the Birmingham City Council and the City of Birmingham. university.
Andy Street, Mayor of West Midlands, said: "[Der Bahnhof] it's overcrowded, it's not the best arrival at the university or the hospital, so it's a better deal for the passengers and a really spectacular entrance to the university campus. "
The university will host hockey and squash for the games and its Vice Chancellor, Sir David Eastwood, said it was "essential" to have a modern chain.
The projects are being finalized and published for public consultation this summer.
