Kingsland Viaduct

From the longer Wikipedia page

Kingsland Viaduct is a railway viaduct about 2 miles (3 km) in length, almost wholly within the present London Borough of Hackney in the north-east part of Inner London. It was built in the 1860s, but was disused from 1986 until it was reopened to carry the London Overground in 2010. The viaduct is owned by Transport for London. Since then it has carried East London Line services between Shoreditch High Street and Dalston.
