Hmmm, OK, pass the bucket, I'm not sure
As a lad, my father and I caught a bus in London, and when we were sat downstairs, my father said to me, 'This is the bus of the future.'
It didn't look or sound any different to me, as the interior was the same colour and trim as the RTs. Years later, when I did a Google about the routes used by the prototypes, I realised that it would, indeed, have been RM1
Many moons later, when I was again working in London, I rode on one of the Boris buses - the new Routemaster and, just because I could, I went down the rear stairs onto the rear platform - and suddenly I was aged 10 again - the colour of the rear vestibule, the shape, the smell, all brought it back - except of course the doors. As a youngster, I could jump off the platform as the bus was drawing to a stop - no safety elves to shout at you then
If you fell over doing it, you learnt how to do it properly next time
