Rail passengers are facing a nightmare journey to work tomorrow as flooding has left part of the Brighton mainline shut.

The groundwater flooding in Patcham has reached such a level that signalling equipment has been damaged - and further flooding is expected.

It means  it will not be possible for Southern to operate its normal service tomorrow.

Instead, a reduced alternative service will run with services between Haywards Heath and Brighton being diverted via Lewes.

A half hourly service will run between Hassocks and Haywards Heath, calling at Burgess Hill and Wivelsfield. Rail replacement buses will run from Brighton to Hassocks. If possible buses will call at Preston Park, but we have been advised of a risk roads may flood, so this will be kept under review. Passengers for London should change at Haywards Heath.

Passengers for London from stations east of Worthing and the east coast should travel via Lewes.

Passengers for London from stations west of Worthing should travel via Barnham and the Arun Valley.

The Argus will be running a liveblog from 6.30am tomorrow morning to bring you all the latest updates from the trains and roads and advising on the best way for you to get to work. Visit theargus.co.uk
