I found this bridge while I was climbing down one of the Swiss Alps next to the famous Matterhorn. I waited about ten minutes for this little train to come over, but I think it was worth it.

Since i am from a totaly flat country (Holland) i do love Switzerland with their over 4.000 meter high mountains. It is one of my favorite countries for sure. I must congratulate you with the composition of this image... the small maintanance train, the viaduct leading the same angle as the waterfall in this image. Very good.
Could this be the Landwasser viaduct maybe ?
