Train operator Scotrail has announced a £475m programme, pledging new trains, thousands of extra seats, more at-seat power points and better wifi. Including improved trains for the north. ScotRail's new High Speed Train fleet will be introduced from autumn 2017 and throughout 2018 and used on the Glasgow-Aberdeen, Edinburgh-Aberdeen, Glasgow-Inverness, Edinburgh-Inverness and Aberdeen-Inverness routes. As this fleet is made up of four and five-carriage trains, rather than current three-carriage trains, the seating capacity will increase on these services by, on average, 36%.
