ScotRail has confirmed that wireless broadband systems will go live at Anniesland, Dalmarnock, Exhibition Centre, Glasgow Queen Street, Helensburgh Central, Mount Florida, Paisley Gilmour Street, Partick, Wemyss Bay stations during today - with Glasgow Central to also receive wifi soon.
Steve Montgomery, ScotRail's managing director, said: "It's exciting to have free wifi at our stations for the first time.
"We know that customers increasingly expect to stay connected while travelling, with more than a quarter of a million wifi users on our express trains each month."
Wifi will be available for passengers and other members of the public to use when in and around the station premises.
When wifi is available, web pages should load faster and emails send more quickly.
Transport Minister Keith Brown said: "ScotRail have worked hard to bring in this first round funded by a £3million Scottish Government investment and we look forward to working together on a further round of station wifi installations to be revealed soon."
Free mobile wifi has already been fitted to all 59 of ScotRail's Class 170 express trains and will be added to its largest fleet of electric trains, Class 380s, this spring.
