Advance warning of rail works - Summer 2021

Southern Railway wanted to let you know well in advance that some major engineering works are taking place in Summer 2021 for nine days.

Where and When?
Saturday 14th to Sunday 22nd August 2021.
No trains will run on the Arun Valley line between Three Bridges and Arundel, or on the Mole Valley line between Dorking and Horsham.


24th, 25th and 31st July to 1st August 2021.
For these two weekends, in addition to the nine-day closure, no trains will run on these lines.

These closures are planned so that Network Rail can replace some of the old track and signalling with modern and more reliable equipment. This will improve journeys on the two routes, as well as the wider region by reducing delays and helping to make services more reliable.
