I can tell you I would not want to do that commute every day from N. Hollywood to downtown via the Red Line. That would be incredibly annoying. What are these people thinking?
Furthermore, I learned something about light rail vs heavy rail, which is that light rail is infinitely preferable to heavy rail. Infinitely. Not only is it less expensive to install and maintain, but it is also, generally speaking, less noisy and above ground, which means that it has better air and much better light. You can see where you are, and see, for example, the Museum of Science & Industry when you go by USC, etc. Heavy rail, e.g. the Red Line, is noisy, unpleasant and expensive. Light rail for me!
We should be grateful that LA has mass transit at all, and not worry too much about whether or not it was well designed (or not). I suppose.
