Default images for ‘tunnels’
For the purposes of the SCRCA Project,
the 'Bridge (Tunnel)' is the structure
that lies between a pair of Tunnel Mouths.
Tunnel interiors are not visible from
outside the railway perimeter, or even
from within a moving passenger train,
so they cannot be photographed
by SCRCA Project volunteers.
