| This
photograph from 1998 shows the view looking down into the cutting from the back
of Williamson's house. If you imagine 2 vertical lines joining the red arrows,
these mark the point where Williamson's triple deck tunnel was bisected. The
triple deck tunnel (so called because it was three layers of tunnel on top of
each other) ran virtually the full length of the central tunnels site. It is
believed still to be largely intact for the present, apart from this gap in the
middle of it! It's easier to make out in real life, but you may be able to see
that outside the 2 lines the cutting face is raw bedrock, whilst between them
it is sandstone blocks. This is where the bisected tunnel was walled up when
the cutting was made in 1881. This is mirrored on the opposite side of the
cutting (beneath the photographer). |
