HP - you're part right and part not. Subway construction was ended in LA because a local politition got a law passed making it illegal. However, he's now going to try to get his law repealed, so the subway may eventually head west thru mid-cities again. However, that's not exactly why we're tunneling now.
The light rail line extending from Pasadena to Union Station in LA is being extended thru East LA, and about 1.7 miles of it needs to go underground. Hence twin tunnels. An underground portion of the light rail line does not make a subway, however, even partly. Our subways are heavy rail, and not overhead OCS fed.
