Multiple incidents along the railway lines caused disruption to services travelling through Horsham this morning (January 4).
National Rail said branches hitting trains, faults on the tracks and a passenger being taken ill had all contributed to delays between Horsham and Redhill.
Many services were subject to short notice alterations or even cancellations and the disruption lasted until midday.
The incidents have since been cleared.
Earlier this morning National Rail said a branch struck a train between Wallington and Waddon. The train later formed a late running service to Tonbridge via Redhill and caused delays.
A fault then occurred on the 08:26 Bognor Regis to London Victoria service as it was attaching at Horsham.
An operational incident between Arundel and Angmering led to further disruption whilst a platform became temporarily blocked whilst waiting for a crew member at Redhill.
A passenger was also taken ill at Clapham Junction.
