Perth has a very efficient and convenient public transport system called Transperth, which operates buses, trains and ferries. Passengers can hop from one to the other on a single ticket, and obtain information on all the services at booths set up for this purpose at strategic points like Plaza Arcade, the railway station and bus stations. Buses in the central area are free, covering a number of colour-coded routes, while suburban bus services and trains link to the outer districts day and night. Ferries operate on the Swan River; fares are based on zones and tickets can be bought from newsagents and vending machines. Metered taxis can be hailed in the street in Perth, found at taxi ranks or booked by telephone. All major car hire companies are represented in Perth and driving in the city poses no problems. Cycling is a popular way to get around, and there are numerous designated cycle routes.
