Four new train services a day could run between Stirling and London from next June.
The Office of Rail and Road has given the go-ahead for Grand Union Trains to start a new service.
The trains will also stop at Larbert.
The routes will run on the existing West Coast Mainline.
The group say the proposed services would increase choice for passengers, "significantly increasing" direct journey opportunities to and from London and central and southern Scotland, while making use of existing capacity on the network.
Stephanie Tobyn, Director, Strategy, Policy and Reform said:
“Our decision helps increase services for passengers and boost competition on Britain’s railway network. By providing more trains serving new destinations, open access operators offer passengers more choice in the origin and price of their journey leading to better outcomes for rail users.”
