Mr Roberts added that the bus industry would "not be slow to spot a need" for improved public transport amid warnings that some nursing staff were threatening to quit over parking shortages.
All Fastlink buses will carry the same branded livery regardless of the operator, and Strathclyde Partnership for Transport - the public body in charge of the service - has said all operators using the route must meet tough targets on emissions, vehicle cleanliness and customer service, as well as using only accessible low floor buses which are fitted with CCTV and smart ticketing technology.
A new Fastlink service, the SouthernFlyer , which will operate from Glasgow city centre to the hospital every ten minutes from 5.40am until midnight, 7 days a week.
In what is a significant investment by First Glasgow, twelve modern vehicles will provide dedicated services on the route. All the buses will be specifically branded in a soon to be revealed Service 77 livery, and fitted with leather seats, free on board wi-fi and extra rooms for buggies and wheelchairs as standard.
The company also revealed that the 77 timetable is specifically designed to reflect visiting times and shift patterns of doctors, nurses and other staff at the hospital. Buses will operate seven days a week, commencing from the city at 5.20am on weekdays and 5.50am at the weekends, with buses from the hospital running until 10.48pm each day.
