Model of a steam locomotive with good hauling and running capacities, not too difficult for a less experienced model engineer. The prototype was produced from 1902 to 1915 by the Swiss Locomotive Works of Winterthur in two versions for shunting and for passenger trains. Of the 82 engines some 20 have survived which are owned by museums or are run by historic steam railway societies of Switzerland
