Drivers are advised to use Oriental Road and Station Approach (Opposite White Rose Lane) for access to the Station House Car Park, which is for premium season ticket holders only.
  • “Buses will run between Woking and Walton-on-Thames every 15 minutes calling at West Byfleet and Weybridge, and call at Byfleet and New Haw every hour.
  • “Alternatively you can use your ticket on Great Western Railway services from Exeter to London Paddington, or from Basingstoke to Reading, and on London Underground services.
  • “If you have a valid season parking permit at West Byfleet or Weybridge, you will be able to park in the car park at Oriental Road in Woking. Please ensure you display your valid permit as usual.”
