The weekly cycle of operations covers pre-assembling of new sections at the depot, the removal of old track from the site and its replacement by new. Timing is arranged to cause least interference to the running of trains. The film also shows measuring up on the site and how the data is employed as the basis of pre-assembly.
There is a version of this film for public audiences under the title Making Tracks.
