Editing East London line (section)

====Physical characteristics====
The line was the only Underground line not to penetrate [[Travelcard Zone 1]] and (apart from the [[Northern City Line|Moorgate to Finsbury Park]] service, transferred to [[British Rail]] in 1976) the only line designed and constructed for mainline trains.<ref name=":0">{{cite book |last=Bextor |first=Robin |year=2013 |title=Little Book of the London Underground |location=Woking |publisher=Demand Media Limited |isbn=9781909217379 }}</ref> At {{convert|5.6|mi|km}} in length it was the second-shortest line (after the [[Waterloo & City line]]), with nine stations and an end-to-end journey time of 14 minutes. It ran in tunnel from Whitechapel to Surrey Quays, with the remainder on the surface or in cutting. Whilst much of the line was built as [[cut-and-cover]], it also contained overground and tube construction features.<ref name=":0" /> The deepest point is at Wapping station, constructed in the Thames Tunnel's original entrance shaft {{convert|60|ft|m}} below the surface.<ref name="linefacts" />

It connected with [[South Eastern Main Line]] services at New Cross and [[Brighton Main Line]] services at New Cross Gate. Underground connections were at Canada Water ([[Jubilee line]]) and Whitechapel ([[District line|District]] and [[Hammersmith & City line|Hammersmith & City]] Lines). A non-contiguous connection with the [[Docklands Light Railway]] was at {{Stnlnk|Shadwell}}, with the DLR station some {{convert|160|ft|m}} away on a viaduct. Although the interchange was via the street, through ticketing was permitted.

A link with the Metropolitan and District lines was made just south of Whitechapel via [[St Mary's Curve]]. This has been out of passenger use since 1939<ref name=Rose/><ref name=CULG/><ref name="LURS"/> but was still used to transfer rolling stock to and from the Metropolitan line's main depot at [[Neasden tube station|Neasden]]. The curve can easily be seen on the northbound and eastbound approaches to Whitechapel station, although a temporary wall was built across the line in January 2008, close to the junction with the District line.{{Citation needed|date=February 2008}}.

Most of the line was double track, with Shoreditch station and the final sections into the southern termini single track, the latter because of lack of space. This required trains to alternate between the two southern termini.
