The Victoria Line Relation 102782 (XML, Potlatch2, iD, JOSM, history, analyze, manage, gpx) runs south-west to north-east across Central London, with a spur to the north to the above ground Northumberland Depot Way 166978969 (XML, Potlatch2, iD, JOSM, history).

Status on OpenStreetMap

The first designs were published in 1948 by the British Transport Commission, 70 years brings these wholesale out-of-copyright in 2018. Being a newer line it has a much larger number of ventilation shafts. The Victoria Line has been mapped primarily from angular surveys at stations, and joining up via the mid-tunnel vents. It will still be some metres off, the position of shafts related to the tunnels can not be easily surveyed—will probably require ground-penetrating radar from street level.
