The Underground tunnel digger is filmed cutting through clay beneath London. The clay falls onto a conveyor and then into small trucks. A finished section is then shown while engineers wait for the other section to break through. Workers smile as they see that the two sections line up.
This clip is taken from the film 'Looking At London: Victoria Line' the full description of this title can be seen on the LMA catalogue, the full film can also be viewed online at www.youtube.com/LdnMetArchives
