Aberdeen to Glasgow Sunday services will also increase from every two hours to every hour.
A new service will also be introduced between Ayr and Edinburgh, which will go via Glasgow Central Station. A new Sunday service for Anniesland via Maryhill is also scheduled, and Glasgow's Anderston station will open on Sundays.
