TRAINS are being delayed on the Redhill to Croydon route due to a signalling problem.
The issue, between Redhil and Purley is causing delays and cancellations on services on the route with big crowds reportedly building at Gatwick Airport as commuters try to head north for work.
Delays of up to 10 minutes are expected on Southern services from Horsham and Gatwick Airport to London Bridge and London Victoria
