RAIL passengers heading out of Cornwall are facing major delays for the next three weeks.
Major improvement works are taking place between Tiverton and Taunton, which will see the line closed and replacement bus services used.
The £15 million Network Rail project is being undertaken on the Whiteball Tunnel, and, once completed, will help increase train speeds on the line.
The works will start this weekend and passengers are warned to expect delays of around an hour on their journey times.
First Great Western’s General Manager for the West David Crome, said: “This £15 million Network Rail work is essential to prevent the aging structure from deteriorating further and to renew rail track.
"While we have done our best to minimise disruption, journeys diverted via Honiton or retimed to ensure customers can arrive in good time will take longer.”
Timetables have been rescheduled, buses will be used to transport some passengers, while some trains will be diverted through Honiton in a bid to minimise the impact.
Early morning trains out of Cornwall to London will leave up to an hour earlier, First Great Western has said.
Customers using branch lines are also advised to check connection times to mainline services due to some services being retimed during the line closure.
