it was in 1954; if so, it's the lowest it has ever been.

It's even more dramatic than that.

I remember the first low-floor Tridents arriving at Barking Garage
(Stagecoach East London), in the T xxx KPU registration series. Within three
or four years, they were displaced away from London by newer Tridents, and I
now see T xxx KPU buses down on the south coast, and also in Cambridge, with
other parts of the Stagecoach empire.
