Abellio ScotRail is training 64 drivers on the route using class 158 DMUs, which will operate services when the line opens.

A proving run took place on June 7 using a ScotRail class 170 DMU to check platform clearances at all seven new stations.

From September 6 ScotRail will operate 33 trains per day between Monday and Saturday and 14 Sunday services between Edinburgh and Tweedbank with a journey time of 55 minutes.

The £294m non-electrified line will restore rail services to an area isolated from the network since the closure of the Edinburgh – Carlisle Waverley Route in 1969. Around 90% of the new railway uses the alignment of the abandoned line.
