HUGE SNIP

Indeed, memory suggests that in parts of the US (Philadelphia spring to
mind) they are sometimes called "trackless trolleys" where "trolley" is
a common synonym for "streetcar" or "tram" (for those of us brought up
that side of the atlantic in the last 40 years, we all remember Mr.
Rogers' Trolley).

When, as a kid in the 1940s and 50s, I visited my grandmothers in Bradford
the trolleybuses were always referred to as tracklesses.
