The Kaeserberg Railway Foundation built one of the largest model railroad layouts in Switzerland. Time taken to build 17 years with a total surface area of 610 square meters in HO scale. There are normal track gauge 16.5 mm (HO) and narrow track gauge 12.0 mm (HOm). The length of the track system is about 2,045 meters. It is a fantastic and amazing miniature world. Meticulous attention to detail has been paid to the landscape and the work of the railway to ensure they are as faithful as possible to the Swiss reality.
