That may well use a 21st Century loading gauge rather than a 19th C

What, 7ft and a half inch?

I was thinking of height.not track width.

There are a few old broad gauge tunnels still in use on the
Paddington-Bristol line.

They are _big_.

They arnt that big , Box tunnel for instance had to have the trackbed
lowered by digging down to accommodate the cables for the recent
electrification .
What makes it look big is a bit of theatrical architecture at the
entrances which are larger than normal but the tunnel becomes smaller
inside after a short distance.

This town used to have a small seaside swimming pool the same shape as
Box tunnel. One of the main contractors for the tunnel came from here,
and he re-used the formwork for the pool roof.
