The record

They ran Chur–Passugg–Tschiertschen and then Zernez–Ofenpass–Müstair, where they cut the crossing of the Ofen from seven hours by horse sleigh to four. Seitz of Kreuzlingen rebodied them in aluminium in 1935, with room for nine passengers, and they were withdrawn in 1939.

AI rendering impression

An AI rendering impression starts from a 3D model of this vehicle, which an image model then paints into a scene. It is an artist's impression of the type, made to give a feel for the vehicle in its element — not a photograph, and not a record of any particular vehicle.

Proportions, fittings, markings, colours and the setting can all drift from the original in the process. For the vehicle's actual details, rely on the specification, the photographs and the cited sources on this page.
