The lines from both Edinburgh & Glasgow via Stirling are due to be electrified by 2018 as part of the modernisation work associated with the Edinburgh to Glasgow Improvement Programme, which will see track layout changes and re-signalling work take place here [REF].
Once this project is completed, a major timetable recast will follow - this will lead to reduced journey times to both main cities and a more frequent service to Perth & Dundee [REF].
