Victoria station in London is a London Underground and National Rail station in the City of Westminster. It is in Travelcard Zone 1. The eastern side, comprising platforms 1 - 8 is the terminus for services to Kent, and the western side comprising platforms 9 - 19 is the terminus for lines running from Surrey and Sussex, including Gatwick Airport and Brighton. Although this split is still generally held to, there are various crossovers allowing trains to access any platform. As the western "Brighton" side is the busier of the two, slight disruption on that line sometimes results in some of its suburban services using the eastern "Chatham" station.
