Transport chiefs are facing fresh calls to spend hundreds of millions of pounds reopening a direct rail link between Perth and Edinburgh.
Councillors will be asked next week to push for a resurrection of the old service, which was closed in 1970 to make way for the M90 motorway.
A new link, which could cut journey times by about 35 minutes, would involve building a new station and park and ride service in Kinross.
A survey from 2009 estimated the line would cost between £500 million and £1 billion.
A motion has been raised by councillors Calum Purves and Mike Barnacle, calling for officials to write to the Scottish Government asking for a review.
Mr Purves said: “There has always been a great deal of support for this in the Kinross-shire area.
“There are a lot of people living here who commute between Perth and Edinburgh, so it would certainly get used.
“It would also build on Perth’s position as an inter-city transport hub, as well as creating real economic benefits for the area.”
A Network Rail spokesman said: “We currently have no plans for reopening this line.”
