The station has three tracks and four platform faces. The London-bound track is a single track with platform faces on either side, both of which are called Platform 1. Until recently, both faces could be used to board London-bound trains, but now only the doors on the ticket office side of the train open, this is due to the third rail being on the other side. Platform 2 serves the Reading-bound line, and Platform 3 serves the Guildford line for trains starting and terminating their journeys at Ascot. Where trains are running from London through to Guildford, or vice versa, they use Platform 2. All lines are bi-directional.
Ascot is served by trains between London Waterloo and Reading with a basic service every 30 minutes Monday to Sunday (there are more frequent trains in the morning and evening peaks – around 4 per hour). Trains to GuildfordviaAldershot operate every 30 minutes Monday to Saturday and every 60 minutes on Sundays. Most of these trains start or terminate at Ascot, but there are through trains from London Waterloo to Aldershot during Monday to Friday peak periods.
During Royal Ascot week, train services from London Waterloo to Reading through Ascot are significantly increased, with trains running every 15 mins in either direction. Even with this increase in service the trains are still crowded.
