A railway line was forced to close after authorities found a car abandoned on the tracks.
Police said the car had left the road then gone down an embankment before being left on the line at Carbis Bay in Cornwall in the early hours of Sunday.
The situation meant the line was closed all day on Sunday, leading to the cancellation of all trains.
Police said the driver of the car had not been found and inquiries are ongoing.
Devon & Cornwall's roads policing team shared images of the car abandoned on the line on Twitter.
The images were posted alongside the caption: "Tickets please! The driver of this vehicle ended up obstructing rail tracks at #CarbisBay having left the road and down an embankment.
"Unfortunately they didn't hang around to help us with enquiries. Enquiries ongoing. @badparking."
In an update on its website, GWR said: "Due to a road vehicle blocking the railway between St Erth and St Ives the line is blocked.
"Train services running to and from these stations will be cancelled. Disruption is expected until the end of the day."
It added: "Overnight a car was driven onto the track and abandoned. The location of the car has made recovery difficult and line between St Erth and St Ives will be closed all day today, Sunday 22 January."
It said Network Rail had made arrangements to recover the car overnight on Sunday so a normal train service could resume on Monday, 23 January.
