The Scottish National Party (SNP) has pledged to consider the case for restoring passenger services on two closed railway lines.
It is to examine the case for upgrading the freight line between Alloa and Dunfermline, which last saw passenger trains in 1930, the party's Holyrood election manifesto stated.
The party has also confirmed it will look into the possibility of extending the Borders Line to Hawick and across the English border to Carlisle.
Paul Tetlaw of transport campaign group Transform Scotland, said: "It would be the perfect opportunity to build on the huge investment of constructing the route through Alloa to Kincardine, by creating a passenger service."
The proposals form part of the party's list of pledges over infrastructure investment, which includes several rail projects.
It will earmark £5 billion for spending on rail projects, such as improvements to the Highland Mainline, the Aberdeen to Inverness line and the Glasgow Subway.
The latter - Scotland's only underground metro service - has already been undergoing enhancements in recent years.
