A man fell from the railway bridge over Montrose Basin on Monday, causing emergency services to be scrambled.
British Transport Police described the episode as a “Trespass incident”.
The main King’s Cross to Aberdeen line was closed for more than an hour as emergency services dealt with the matter, and Scotrail arranged alternative transport for affected passengers.
Police were alerted after 1pm by an alarmed member of the public who had spotted a man on the bridge.
The area was cordoned off and Lifeboat and Coastguards were alerted.
However, the man’s location was over an area of mud, so the inshore boat was unable to get into place to assist.
A Lifeboat spokesman said the inshore boat was paged at 1.10pm regarding an incident at the rail viaduct.
The boat was stood down at 2.12pm due to the ebb tide.
“It returned to base with the incident unresolved.”
An eyewitness told the Review that as he drove out of the town he saw a large number of emergency vehicles at the former Strathtay bus garage on Rossie Island.
He was then aware of two people on the high brick viaduct, one of whom was a policewoman in conversation with the other.
The man was treated by emergency services who indicated that his injuries were not thought to be life-threatening.
No details have yet been made available about the man’s present condition or his identity.
