Rail services across the Westcountry continue to be disrupted following yesterday's heavy rain.
Due to a landslip between Exeter St Davids and Yeovil Junction all lines are blocked. Train services running through these stations will be cancelled and major disruption is expected until the end of the day on Wednesday 6 December.
The service to London Waterloo will be cancelled until at least tomorrow night and potentially through to the weekend.
Great Western Railway also said it expected disruption to its service from London Paddington to Devon and through to Cornwall, until Tuesday afternoon, with journey times being extended by up to one hour.
GWR said: 'Due to heavy rain flooding the railway between Taunton and Westbury, all lines are blocked.
'Train services running through these stations will be delayed or diverted.'
A National Rail spokesperson said: 'The recent heavy rain and flooding is causing earth to move above the Crewkerne Tunnel and the line is closed to all services on safety grounds.
'Engineers will conduct a further daylight assessment of the site on Tuesday and the tunnel will definitely be closed until at least Thursday 7th December.
'In addition to this, heavy flooding of local roads is affecting the replacement bus services running between Salisbury and Yeovil Junction.
'With further rain forecast in the next 48 hours there is potential that no services will run until the weekend.
'Please do not attempt to travel between Salisbury and Exeter on Tuesday 5 or Wednesday 6 December.'
'Passengers who had already started their journey on Monday 4th December and sourced their own taxis can claim them back through the customer services team. Customer services will require:
Your full contact details
