Rail passengers in the Horsham district have been facing delays and cancellations earlier this afternoon (Tuesday October 14).
A signal failure in the Barnham area and a electrical power supply problem in Pulborough area have caused problems for commuters.
Southern say services have been subject to delays of up to 20 minutes and short notice cancellations.
They do say, though, that trains are now able to call at Arundel, Amberley, Pulborough, Billingshurst and Christ’s Hospital.
The problems were expected to be sorted by 2pm.
However, customers are advised to listen carefully to all station and on-board train announcements for further details.
