Too Contrived - Using a Road-Over Bridge As A Tunnel Entrance?

Chipping Norton was in my mind as well.

 

You could check out some of Ian Rice's ideas. Depending on the height you will be viewing the layout at you may find that a well placed building provides a good enough sight block to enable trains to depart from the visible scene

 

Yes, certainly worth investigating.

Castle Cary has 2 bridges very close together at different angles, one for the weymouth line, one for the mainline

 

Thanks 37114,

 

Yes, I know that location quite well, we pass it regularly on the way to the toy fairs at Shepton Mallet.  Must stop and actually get out for a look next time.

Don't forget that the word tunnel doesn't only have to apply to routes under hills.

 

The answer could like in the term 'cut and cover', Southampton tunnel as pictured above has very little ground cover and certainly could have been built as a cutting if it were not for political and landowner issues. Ryde tunnels on the Isle of Wight were not needed from an engineering point of view (particularly as this took them below sea level)  - it was insisted on by the local council who refused to countenance a surface route. Naturally in such circumstances the tunnels are very near the surface and nothing can be built on top of them except roads. In the peak district Haddon tunnel was built to pacify a local landowner and IIRC at least part of it was constructed via the 'cut and cover' method with extra earth being dumped around and on top of it because in reality the ground levels were too shallow for a tunnel.

 

Alternatively please remember even the Victorians were not adverse to building 'rafts' so as to allow overline development (its not just something that started to happen in the 80s) so again there are possibilities
