Warning over Dorchester to Bournemouth rail disruption
Rail passengers in Dorset are being warned they could face major disruption as a £40m project is completed.
The project has seen new track laid to allow a regular train service to run from Swanage to Wareham for the first time in more than 40 years next year.
Signalling between Dorchester South and Bournemouth is also being replaced.
Buses will replace trains between Poole and Dorchester South on Thursday and Friday and between Bournemouth and Dorchester South at the weekend.
Network Rail and South West Trains Alliance said bus services would be supplemented by a shuttle train service between Dorchester South and Weymouth.
It has apologised for any inconvenience caused to its customers.
Swanage Railway plans to deliver trial services between Swanage and Wareham for 50 days in 2015 and 90 days in 2016.
It is hoped a year-round service on the volunteer-run heritage line will follow.
