Light Railway stations are Canary Wharf, Heron Quays, South Quay, Crossharbour, Mudchute and Island Gardens. Sand siltation required dredging, which weakened the quays; one quay collapsed in 1924. Together with Heron Quays and Wood Wharf, it forms the Canary Wharf Estate. Recently constructed canals include Harbour Quays and Riverlinks completed in 2007. The Grand Harbour is Malta's major port, with unloading quays at nearby Marsa. Special liabilities also lay upon riparian owners to repair canals, bridges, quays, etc. Rotherhithe, Canada Water and Surrey Quays are all served by London Overground trains. The city is further intersected by numerous small canals with tree-bordered quays. Land was reclaimed so quays and warehouses could be built. Thunderous jubilation resounded from quays, streets, windows and rooftops. Agecroft Rowing Club currently operates from Salford Quays. Bunkering is available on the jetty and at quays 2, 3, and 5. Others dealt with sanitation, fire regulations and upkeep of the city wall, quays and pavements. Newcastle and Worcester each had a Grope Lane close to their public quays. The new theatre would open on to the Liffey quays.
