One Tamar bridge has a unique design:

The upper arch expands under load, the lower one contracts and cancels
the upper's end thrust, thus the supporting piers can be quite narrow
and the abutments curved to match the track right-of-way.

I pass that, the Saltash Bridge, travelling back to Devon of I go the
South-of-Dartmoor route through Plymouth.
From the road suspension bridge the 1850's Brunel railway Saltash bridge
is alongside.

It is a spectacular sight.
Many Brunel solutions are very special - there is a clean rationality to
the design, as best I can put it.
