Transport Sydney's CBD is serviced by commuter rail, light rail, bus and ferry transport. Sydney's main commuter rail hub is Central railway station ("Central"), which is located to the south of the CBD in Haymarket: it connects services for almost all of the lines in the Sydney Trains network, as well as being the terminus for NSW TrainLink country and inter-urban rail services. From Central, there is a largely-underground CBD rail loop, accessed in both directions via Central, which services five CBD stations (Town Hall, Wynyard, Circular Quay, St James and Museum). This is known as the City Circle. In addition, a separate underground line to Bondi Junction services an additional underground station, Martin Place. The Inner West Light Rail passes immediately to the south of the CBD, connecting Central to nearby suburbs of Sydney's Inner West. The CBD and South East Light Rail runs north–south through the CBD, connecting Circular Quay with Central and the south eastern suburbs. Buses service the CBD along several dozen routes to both inner and more remote suburbs. NightRide is an after-hours bus service that operates between midnight and 5:00 am, with most services running from George Street outside the Sydney Town Hall. Sydney Ferries operate largely from Circular Quay, on the northern edge of the CBD. There are several wharves (directly beneath the elevated Circular Quay commuter rail station), with Wharf 3 operating exclusively to Manly. There are also ferries services from the western edge of the CBD at Barangaroo. Additionally, the rapid transit line connecting the northwest suburbs with is planned to continue to the CBD when the second stage of the Sydney Metro is completed. This rapid transit line is underground in the CBD area and will link the North Shore to Bankstown via a tunnel underneath Sydney Harbour and the CBD. It is currently under construction, with a planned completion date of 2024. Construction on a separate rapid transit line to connect the CBD with the secondary centre of Parramatta
