Yes, trains are running very frequently between Glasgow and Edinburgh in 2026, as this remains the busiest and most vital rail corridor in Scotland. There are four different routes connecting the two cities, with the fastest being the service from Glasgow Queen Street to Edinburgh Waverley via Falkirk High, which takes approximately 45–50 minutes and runs every 15 minutes during peak hours. There are also slower but reliable services from Glasgow Central and via Airdrie/Bathgate. While service is generally excellent, travelers should be aware of a specific disruption in early 2026: from January 12 until April 19, 2026, the ScotRail station bus link (which connects Glasgow Central and Queen Street) is unable to serve its usual stops due to roadworks, requiring a short walk between stations. It is always recommended to check the ScotRail or National Rail apps for "Live Departures" before heading to the station, especially on weekends when engineering works can occasionally cause temporary diversions or replacement bus services on the secondary routes through Shotts or Carstairs.
