A 4 billion pound proposal to run and expand the railways has been revealed by Network Rail.
Key developments for Scotland include the electrification of the Edinburgh Waverley to Glasgow Queen Street route which is expected to shorten journey times and increase capacity.
The completion of the Borders Rail Link will see 30 miles of track reopened between towns in the Borders with Edinburgh at a cost of #360 million.
These Scottish projects are part of a £37.5 billion plan to run and expand the UK railways for 2014-2019.
