Our thanks to Patricia.Ferguson. MSP, for forwarding this information as soon as it has been released by ScotRail. We have not had time to navigate its comprehensive information yet, but I am sure that it will give you an insight into the widespread timetable and route changes which will come into play from 20th March, 2016 for a period of 20 weeks as a result of the closure of the Queen Street Tunnel. The main webpage is here –

However, I am sure that you will be really interested in the new timetable for the Anniesland -Queen Street Service from 20th March for that 20 week period.
