Die Poste Mercedes 0405 at La Chaux de Fonds

This Swiss post bus seen in La Chaux de Fonds inherited the registration number off a Saurer DUK which had been withdrawn and sold a number of years earlier. There was not much of numbering system once the Die Poste was split off what became Swiss Telecom but it didn't matter too much as a few years later vehicles were to lose their famous P-Reg for Cantonal marques. The problem with that was each time a bus moved to a different area it received a new number and most likely something else when it returned. With that in mind one might have thought the large fleet would have by then carried fleet numbers but they don't and so the onlooker can guess very little about it.
