Buses would link the new station with the main centres
The first designs for a new Parkway station in Gloucestershire have gone on display to the public.
A site between the Elmbridge and C & G roundabouts has been earmarked for the possible development.
Buses would link it to the centres of Cheltenham and Gloucester and to park-and-rides and business parks.
The designs can be seen at Shire Hall or on the county council website. The proposals will be submitted to the Department of Transport for funding.
Gloucestershire Parkway is part of the Great Gloucestershire Debate, a public consultation exercise to discuss major issues in the county.
At the launch of the debate last month, road experts warned that traffic at the Elmbridge Court roundabout could come to a standstill by 2011 unless the number of cars are reduced by a third.
Councillor Stan Waddington, Cabinet Member for Environment, said: "We believe a Gloucestershire Parkway would improve access to the rail network for people over a wide area of the county together with improved levels of rail service.
"Supported by the improved bus links, we hope this will lead to increased public transport use and relieve congestion particularly in the central Severn Vale."
