Built in 1940 as a departmental wagon on old bogies from a tender from a Gotthardbahn steam locomotive, this vehicle was rebuilt in 1963 into a mobile workshop. On this occasion, the braking system was modernized, saving the old brake shoes.
We
had the forethought to build a bar for the heavy set, with a compartment to
carry cycles ... this car would be given to the  Bahn 
Museum Kerzers which he reached at the 8th of March of 2008, together with the
E 3/3 ex RVT 8.
