I have been advised of over-night work taking place on the railway line between Sanderstead and Riddlesdown Stations, Network Rail have advised that essential maintenance works will be undertaken from midnight on Tuesday 31 August to 05.00hrs Friday 3 September 2021. i.e. starting the night/morning after the Bank Holiday. This work is taking place each night rather than during the day.
These works will involve installing rails and moving ballast using an engineering train and other equipment. This will involve the use of a rail delivery train and heavy track plant to remove and install the rails and other components. The equipment used will mean that some disturbance is unavoidable, but they every effort will be made to to minimise unnecessary noise.
As the rail line between these two stations is mainly in the valley, noise will reverberate around the valley and beyond. For those using the trains between London and East Grinstead/Uckfield, it does mean the late night and early morning trains are cancelled, and buses will replace the service (not for Riddlesdown Station).
