Bondholder Derby City Council has given the go-ahead to create a new platform at Derby Midland Station.
The plans outline the construction of a new platform on the Pride Park side of Derby Midland Station, resulting in six "through" platforms.
The new platform will not only help ease congestion at the station, but will also help increase capacity.
Network Rail, who submitted the plans, said: "We have recently submitted designs for a new platform at Derby station to Derby City Council for prior approval, as part of our project to remodel the track at Derby Station in 2018.
"This upgrade is a significant piece of work that will bring journey time benefits to passengers travelling to, from, and through Derby."
The new platform is part of a £200m upgrade to the station, which includes changes to signalling and the tracks.
