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.
