Swiss Miniatur Melide

There are around 120 models, among which visitors will recognise not only the country's best-known stone miniature, but also the Glacier Express. 5 metres long and to a scale of 1:25, the model runs the lenght and breadth of the exhibition on a 42-metre track with a gauge of just 46 millimetres.
