A lovely film showing footage of Walsall's trolleybuses in the late 1960s in the last few years of their service before finally being withdrawn in 1970. It was one of the last UK trolleybus networks to be closed and i've never seen a working one in this country (i have seen one in Spain).
Of course in hindsight losing such a network (and the tram networks) was a mistake which is slowly being rectified via various costly new tram schemes... Anyway apart from the vehicles themselves it is an interesting look at Walsall the place too.
AMRTM used to have one of these trolleybuses (they may still do but haven't been to the museum for awhile).
