I wouldn't choose any of these WHS mainly because I would choose other WHS which would still encompass transport and trade aspects
I think that is a pretty valid point, though I'm not sure anything would encompass transport as well as the Grand Canal
, communications as well as Grimeton
. And like Solivagant I think Railways are deserving of some representation, the choice is between the quirky mountain railways, or the impressively engineering but somewhat uninteresting Alpine passes, perhaps the Forth Bridge
is a good compromise, built for rail but also representing railways?
