RMweb Premium Martino Posted March 2, 2021 RMweb Premium Share Posted March 2, 2021 I’m in the process of building a truss bridge for my garden railway. 16mm/ft and the bridge is constructed in aluminium. My railway is supposedly English narrow gauge (3’). Strangely, I’ve never been on truss bridge so don’t know if the actual deck would be solid (in which case what material?) or with the rails and sleepers just resting on cross members? Or would I get away with a metal mesh? I’ve searched here and on the web for photos of prototypes but can’t find anything showing the actual deck. Any suggestions would be very grateful received.

pb_devon Posted March 2, 2021 Share Posted March 2, 2021 Might depend on what the bridge is crossing. If a river, then it could be open (nothing underneath to damage), but if a road then a closed deck to protect passing traffic/people below. As for material....timber or solid formed steel. 1 Link to post Share on other sites More sharing options...

RMweb Premium Martino Posted March 2, 2021 Author RMweb Premium Share Posted March 2, 2021 Thank you both very much. That’s incredibly useful. The bridge is over a boggy valley so I think a timber base like Bryan y Felin will be the way to go. Very many thanks again. Link to post Share on other sites More sharing options...
