Cornwall commuters could face disruption while a multimillion pound rail improvement project between Devon and Somerset is carried out.
The £15 million project will see the railway line between Tiverton and Taunton closed to allow Network Rail to make repairs to the iconic Whiteball Tunnel to be completed.
Work will begin next Saturday (January 18) and run for three weeks.
Timetables have been rescheduled and 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, the train operator has said.
David Crome, First Great Western’s general manager for the West, said: “This £15 million Network Rail work is essential to prevent the ageing structure from deteriorating further and to renew rail track.”
Work will also be carried out on renewing the track and improving drainage and flood prevention on the embankment as part of a wider programme to alleviate risks to rail caused by extreme weather.
Customers using branch lines are also advised to check connection times to mainline services due to some services being retimed during the line closure.
