We had a wonderful experience on Monday with Raymond & Louis & the Hans Meier team going to Jongfraujoch on the cog trains. We booked our tour from Zurich originally for Sunday but the company kindly agreed to change it to Monday as we carried in Zurich Saturday quite ill. The tour went thru Luzern and Interlaken on its way to pickup the first cog train. Being in a group we had reserved seats on the cog trains. The whole trip was spectacular. Anyone going to Switzerland surely has to do this incredible tour.
