I was actually looking at the covered lattice bridge which looks to be taller that the bowstring. The picture shows the OO engine clearing the roof by a lot.
Thanks Nigels for taking the time to show us. This bridge might also be used as an inverted bowstring bridge in which case the clearance wouldn't matter. Would it work with your assembled bridge Nigels?
