TWO people were taken to hospital after spending an hour in the water when their boat capsized in the Clyde off Cardross on Thursday.

According to the HM Coastguard, the pair had been in the water for around an hour when they were spotted by the driver of a passing train who stopped to help.

ScotRail initially advised that trains were not running between Helensburgh and Dumbarton after reports of trespassers on the line - until HM Coastguard shed light on the real story.

In a post on Facebook a spokesperson for Belfast Coastguard said: "At 15:26 hours this afternoon Coastguard personnel from Greenock, Helensburgh and RNLI Helensburgh attended a capsized vessel with persons reported in the water between Port Glasgow and Cardross.

"Two persons had been in the water for a considerable time when they were spotted by a passing train driver who stopped to assist.

"Both persons were safely recovered from the water.

"One casualty was taken by Coastguard Rescue Helicopter 199 to the Queen Elizabeth University Hospital in Glasgow and due to difficult terrain a second casualty was assisted via rail to Cardross train station to meet awaiting Scottish Ambulance Service SORT [Special Operations Response Team] crews.

"Both casualties were thankfully wearing floatation aids which has kept them afloat whilst being in the water for approximately 60 minutes.

"With thanks to ScotRail [and] British Transport Police Scotland for their assistance."

ScotRail later reported that services had begun to return to normal by 5pm.
