Two people were rescued from the River Clyde after a train driver spotted them while on shift.
The stricken pair were seen in the water between Port Glasgow, Inverclyde and Cardross, West Dunbartonshire on Thursday afternoon. A ScotRail train was passing by and the driver stopped locomotive to help the seafarers whose 15ft boat had capsized.
Both had been in the water for around an hour, were relying on lifejackets and shouting for help. Emergency crews raced to the scene and one was airlifted to Glasgow's Queen Elizabeth University Hospital.
