Flooding has closed part of the railway line in Cornwall, Great Western Railway (GWR) has confirmed.
Train services running between Liskeard and Looe have been cancelled and disruption is expected until the end of the day, the firm said.
It said Network Rail was monitoring water levels and inspections would need to be carried out before the line was reopened.
GWR said it was sorry for the disruption and added it had requested replacement transport options between Liskeard and Looe – and would give details once they had been confirmed.
