Rail users could face cancellations after a lorry hit a bridge in Perth.
Scotrail has warned that commuters using the Glasgow to Aberdeen service, taking in Dundee and Perth, could be delayed or even scrapped following the incident.
Emergency services were alerted shortly before 12.20pm today.
Damage to the bridge and the vehicle is minimal but Network Rail engineers have been called to the bridge to inspect the structure, meaning disruption could last until 2.30pm.
A bridge examiner has given approval for trains to pass, but at a reduced speed.
A spokesman for Police Scotland said: “We were called at 12.18pm after a black lorry struck the bridge on Tay Street.
“There is no damage on the road and the driver is OK.
“The incident is now in the hands of Network Rail.”
A statement from Scotrail said: “Due to a road vehicle colliding with a bridge between Dundee and Perth trains have to run at reduced speed on all lines. Disruption is expected until 2:30pm.
“Our staff has examined the line and is happy that trains can pass by safely. These services will run through at a reduced speed until a bridge examiner can confirm and allow train to run as scheduled.”
