At Aiglon College in Chesieres-Villars where I went to school, part of my fascination for the post bus fleet was that apart from our two there was hardly another example to be found for miles and I used to look forwards to school trips as I might see some more of the PTT owned 496 buses. Unlike today where they all wear the same livery the contractors buses carried the post horn but were either cream or in operator's colours.Unlike in this Sunday view at Hasilberg on the Brunig Pass, usually if I did see any it was just glimpses of them as our train raced through sleepy stations. After Saurer who already Had absorbed FBW, sold out to German giant Daimler-Benz they continued to build buses to Swiss specification named NAW at the former plant at Arbon including the 10.620m long BH 4-23 which was the then legally permitted size for alpine roads. The PTT took forty-five of these buses for it's own 'P registration fleet from 1985. P24427 was still new when photographed early in 1990. Had I come a few months earlier I might have seen an old FBW PCUA dating from 1964 when I was at school. Now that would have been worth getting off the train for!
