Rail services have been disrupted and a road is blocked because of a level-crossing failure in Billingshurst this morning (Monday April 28).
Emergency repairs are taking place at the site in Lower Station Road.
The road is reported to be blocked near the Daux Road junction.
A Southern Rail spokesperson said: “Southern will be operating a reduced service between Horsham and Barnham today owing to a level crossing failure at Billingshurst. As a result of yesterdays failure services will be subject to alteration and cancellation and also subject to extended journey times of up to 20 minutes.
“No direct services will operate between Portsmouth/Southampton towards London Victoria all day in both directions.
“Customers will be required to change and use local services between Brighton and Southampton/Portsmouth.
“South West Trains are also accepting Southern tickets between Southampton/Portsmouth and London today.”
