Aside from local bus routes, the area is primarily served by the DLR which goes from Canning Town (services west to Canary Wharf and Central London, and North to Stratford) along the north of the dock to Beckton, and along the south of the dock to North Woolwich and under the Thames to Woolwich Arsenal. Transport for London plan to extend the Beckton branch to Dagenham but this is dependent on funding. The DLR replaced the North London Line services that previously served the area from Canning Town to North Woolwich via Custom House and the 600 m Connaught tunnel beneath the docks.
