A £2million boost will transform the stations which form Glasgow's gateway to the 2014 Commonwealth Games.
Scotland's Deputy First Minister Nicola Sturgeon has announced major investment by ScotRail, following agreement with the Scottish Government, that will see stations serving the 2014 Commonwealth Games improved.
Stations in line for refurbishment include Queen Street low level, Charing Cross and High Street, doubling a £1m programme of work already announced across 20 stations in Strathclyde.
Further enhancements are currently being agreed between Transport Scotland and ScotRail.
Rail chiefs say the investment will deliver improvements for commuters and a fresh new look for the city's busiest stations ahead of the Games.
Ms Sturgeon, who announced the latest investment on a visit to Glasgow Queen Street station today, said: "Almost 20million commuters already use these three key Glasgow's stations every year.
"This investment will deliver a £2m transformation of these, and other, stations, boosting capacity and improving accessibility.
"I am delighted to be able to announce this significant investment for stations serving the Games and I look forward to seeing the improvements to these stations developing in the lead-up to 2014 and delivering a lasting legacy for rail users."
Transport Scotland secured the first £1m of the funding boost from First ScotRail as part of the five-month continuation of the rail franchise announced in December.
ScotRail managing director Steve Montgomery said: "We have a host of improvements planned including more seats and additional train services, as well as upgrades and enhancements at some of our stations."
David Grevemberg, Glasgow 2014 chief executive, said: "This investment recognises the vital role public transport plays in ensuring delivery of a successful Games.
"Glasgow 2014 welcomes the funding announcement made today by Transport Scotland."
