but I don't really know what they're called. I have mainly seen them in the Alps where they are built over roads/railways mainly for avalanche protection although I am sure they have other uses. I have always called them 'train galleries' but obviously searching for that on Google images just brings up plenty of images of trains! Does anyone know a better name for them?
Perhaps some of our foreign friends could let me know their German/French name as that will obviously work in Google too!
Thanks
