When I was a child in the 1960's my mother hauled a pushchair on and
off RM and RT buses, either on her own or probably with the help of
the conductor. (Blimey, I'm starting to see Boris's point about buses
here!). This was normal practice and no-one complained. My mother is
hardly the largest or strongest person either. I also travelled in the
guards compartment of trains as well, and can remember doing the same
thing whne my sister was little in the early 1970's.
