VEHICLE & PAX
In the days of the "traditional: double-decker, eg Routemaster,
conductors would call 'seats on top" and persuade passengers to go
up rather than stand in the lower saloon.

Standing capacity was limited, with none of what the old
regulations used to call "perambulators or other wheeled
conveyance" - in other words, baby "buggies"

Actually, the space under the stairs was for stowing things like (folded)
buggies and quite well used as such in my schooldays.
