Again: can you make this more concise? I really tuned out when I saw this wall of text, and I didn't see my question answered in the first sentence or two before you went into your exposition (in fact, it seems you ignored my question).
I was astoundingly "concise" and answered your specific question in my first, short sentence:
You asked
> Are you suggesting that a metro system, like MTA or BART, is the same as a high speed rail? They serve fundamentally different purposes.
and my answer started with
> They are passenger trains.
That's the answer directly to your question, in the first sentence and just four words. So, the answer is right there, right up front, the first thing, nicely "concise", in just four words.
Apparently you did not see those four words as answering your question. Well, then, my four word answer was too "concise". So, I went on with what you call a "wall of text" and explained just why being a "passenger train" is the problem, different "purposes" or not, fast or slow, long or short, etc. The answer to your question is right there, short, concise, right at the beginning, in just four words and, then, if that is too short, with lots of detail.
I typed it in. All you have to do is read it. If the four word answer is too "concise", then read the "wall of text".
