Two casualties were rescued from the Clyde after their boat capsized and they were spotted in the water by a train driver.
The pair had been in the water for an hour before they were spotted by a passing ScotRail driver between Port Glasgow and Cardross. A Coastguard Rescue Helicopter took one casualty to the Queen Elizabeth University Hospital in Glasgow after they were recovered from the water.
The other person was taken to Cardross train station by rail where they were met by the Scottish Ambulance Service. Coastguard crews from Greenock and Helensburgh, as well as the lifeboat at Helensburgh, were scrambled to the scene at 3.26pm on Thursday, Greenock Coastguard said.
"Two persons had been in the water for a considerable time when they were spotted by a passing train driver who stopped to assist," the Coastguard spokesman said.
"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 crews.
"Both casualties were thankfully wearing flotation aids which has kept them afloat whilst being in the water for approximately 60 minutes."
Their condition is not known.
