Planned engineering work
Network Rail needs to do engineering work to maintain and improve the rail network. Much of this work is done at weekends and during holiday periods, but some work also needs to be done overnight during the week.
Buses will replace train services where lines are closed for work to take place. We may also have to alter train services over a wider area.
Please use the Engineering Work calendar and click on a date to get information about planned engineering work for that day.
For the latest information on how London Underground services are running, we recommend you visit the "Transport for London" website.
Bournemouth to Weymouth re-signalling scheme
A major part of the work to re-signal this stretch of line will take place in May. The engineers need four days of access to the line to do this stage of the work, so services will be affected Thursday 15 and Friday 16 May as well as the weekend of 17/18 May.
On Thursday 15 and Friday 16 May the lines between Poole and Dorchester South will be closed. Replacement bus services will run between Poole and Weymouth, supplemented by a shuttle train service between Dorchester South and Weymouth.
On Saturday 17 and Sunday 18 May the lines between Bournemouth and Dorchester South will be closed. Bus services will run between Bournemouth and Weymouth, supplemented by a shuttle train service between Dorchester South and Weymouth.
We are sorry for the disruption this work will cause, especially for customers travelling to stations between Poole and Weymouth. This work is an essential part of the investment programme to bring all the South West Trains area under modern and more reliable signalling control.
