The high level station serves a mainline to Edinburgh, with modern diesel trains completing the journey to the capital in about 45 minutes, with onward connections to Fife and Aberdeen. A line also runs Perth, passing through Larbert, Stirling, and Dunblane. Also leaving from the high level are trains on the West Highland Line, taking in the spectacular scenery as far as Fort William, and then onto Mallaig.
The low level station links with the Glasgow suburban electric network. Trains run frequently between Helensburgh, on the Firth of Clyde, and Airdrie - on the edge of the West of Scotland conurbation.
