than buses, then by all means let's do it. If the MTA had plans to put trolleys on every major street in LA, then I would ecstatic. But they are not. They are planning to build four or five multibillion dollar light rail lines and one heavy rail extension over the next several years, and then cut service everywhere else. In a city of 400 square miles that means by their own calculations no change in mode share between private automobiles and alternatives and a huge increase in greenhouse gas emissions even after it's all built. That ought to be unacceptable to anyone concerned about the environment.

I've lived in SF and trolleys are great, but they are not fast unless they are running in an exclusive guideway, in which case you're really talking about light rail and 150-200 million a mile, more for a subway.

But by all means, let MTA and anyone else know about any alternatives that could actually be built given available resources to go enough places to provide a real alternative to the private automobile in Los Angeles. Right now, the only thing that does that is the bus.
