Somerset freight derailment delays to last into weekend
Work to remove a derailed freight train carrying stone aggregate causing rail problems to the west of England may last until at least Saturday.
Network Rail says engineers are working "around the clock" to reopen the track between Westbury and Castle Cary.
The operator said the derailment caused significant damage, ripping up track and sleepers.
Rail passengers are being told to expect delays between Taunton and Westbury, and Westbury to Weymouth.
The Network Rail spokesman said: "The incident on Monday evening caused significant damage to the railway, ripping up track and sleepers, and derailing several freight wagons full of stone aggregate.
"The next 24 hours will see operations using specialist engineering equipment to begin removing the damaged wagons from the site."
The train was pulling 38 wagons filled with stone and ballast, seven of which derailed on Monday evening.
Rail replacement services are operating between Castle Cary, Bruton and Frome.
High-speed services between London Paddington and the West are being diverted via Bristol with longer journey times.
"Several de-railed wagons are still full of stone and sand, and engineers advise that a great deal of preparatory work has to be carried out prior to them being moved or scrapped on-site," Network Rail's spokesman added.
