The first half of the route from Glasgow to Dunblane runs along the Glasgow to Edinburgh main line as far as Greenhill Upper Junction where it diverges to the left. The route then continues through Greenhill Lower Junction where the line from Cumbernauld joins, then through Carmuirs to Larbert and onwards to Stirling. The line splits after Stirling to both Dunblane and Alloa where the electrification of the routes currently ends. From Dunblane the main line continues to Gleneagles and Perth for services to the north of Scotland. Electrification of the 35 mile route from Glasgow Queen Street high level station to Dunblane was completed in 2019. The 7 mile branch line from Stirling to Alloa was also electrified as part of the Network Rail improvement programme (EGIP). Class 385 Hitachi electric multiple units now provide commuter services to both Edinburgh and Glasgow.
