Around 500 advance tickets have been sold to passengers travelling north from the Tweedbank or Galashiels to Edinburgh on the first day of the new Borders Railway on Sunday.
A Scotrail spokesperson has also revealed that around 200 tickets have been sold to passengers planning to go the other way from Edinburgh to the Borders.
Scotrail expects the very first regular service, which departs Tweedbank at 8:45am on Sunday morning, to be extremely busy and is advising passengers to spread their journey throughout the day to avoid long queues.
Tickets are available to buy on the day, and Scotrail is expecting “thousands” to make journeys in both directions on Sunday. Extra carriages are being added to all services to cope with the high demand.
A Scotrail spokesperson said: “We are expecting lots of people to turn up in the hope of catching the very first train on Sunday morning. To avoid disappointment and the prospect of long queues, we are asking passengers to consider later trains running later in the day.”
