@deltaonefour - no you don't understand. The article isn't trying to sell you anything. I'm not trying to sell you anything. The article is literally just a nice short explanation of a relatively obscure (but apparently popular) topic - why the BART chose a specific gauge. It's not saying BART is faster, higher capacity, cheaper, cleaner, more modern or in any way better than anything else in the rest of the world. It's just about the gauge, nothing more. There's no need to get so upset about this.
