The article says that 50 years ago the term "light rail" was not used for the electric vehicles that ran in Los Angeles and environs--they were trolleys. This is not true. They were streetcars! The only people, other than those on Mt. Lowe, who ever used the word "trolley" were foreigners (i.e., non-Angelenos) and were immediately identified as such. We natives kindly corrected them.
I was born in Los Angeles, have lived here all my life, went to junior high and high school on the streetcar, went downtown and to Hollywood on the streetcar so know whereof I speak.
Incidentally, I never see or hear mention these days of our subway which ran from Beverly Boulevard to the Subway Terminal Building on Hill Street. The currently proposed subway will not be the first one in Los Angeles.
