This page acts as a diary holding
before and after photographs on the work as it
progressed. Click on the images to see them full size; use
your browser's 'back' button to return to this page. It is useful
to compare these shots with some of the historical photographs
from the 1930s to 1960s for some of the locations, accessed using
the link under the location name (for more examples of historic
photos, and some video footage of the line in operation, see the
'Photo Archive' page elsewhere >>). For
some locations some video footage of works in progress is available
through the 'video' link (requires a video player in
wmv format).
