Head of customer operations Phil Campbell said: “We’re set to have a great weekend of sport, and with lots of fans travelling to events right across Scotland, it’s going to be a busy few days.
“To help the events run smoothly, we’ll be adding extra seats to hundreds of trains over the weekend, and although we can’t make every train longer, we will be using every train we can.
“I encourage anyone travelling this weekend to allow extra time for travel and buy your tickets in advance.”
