A ScotRail spokeswoman said: “Borders Railway has been an extraordinary success.
“We are now providing people with an alternative way of travelling to work, to visit friends and family and to use for leisure.
“There have been some challenges and we’re determined to find the solutions that overcome them and see even more customers travelling on the line in year two and beyond.”
Transport Scotland said: “The ScotRail 158 fleet is currently undergoing a £14m refurbishment programme delivering significant upgrades to on-train facilities.
“As more refurbished trains are completed they will be rolled out onto central belt routes, including Borders, next year, increasing capacity and reliability for passengers on the Borders Railway.
“Additionally, the electrification of the Central Belt rail network and the introduction of our new electric fleet of trains means there will be extra capacity on peak Borders services from 2017.”
