The train line between Dundee to Perth is closed this morning after a fire.
According to Scotrail there was a blaze next to the track in Perth last night but there also reports of a fire in a signal box close to Longoforgan.
No trains to and from Glasgow Queen Street are calling at Dundee. Instead, a replacement bus is serving passengers between Dundee and Perth, where they can pick up trains to Glasgow Queen Street.
It is not known how long the disruption will last.
ScotRail tweeted at 6.21am: “Staff are on site and performing their investigation, after this an estimate will be given for repairs to be completed.”
