Monday 1 November to Wednesday 3 November, 9pm to 4am each night.

There will be night works between Burnley to Box Hill and Camberwell to Alamein while maintenance takes place.

Due to the nature of the works and heavy machinery required, including special track machines, excavators, front end loaders and chainsaws, medium to high level construction noise will be experienced. While these works take place you may also experience more local traffic from work vehicles and replacement bus services. Every effort will be made to complete works within these time frames, some activities may need to be rescheduled in the event of bad weather or other unavoidable circumstances. These works are to ensure the ongoing safety and efficiency of the network. Thank you in advance for your understanding during these works.
