Wow, a train line goes defunct in a country that heavily subsidizes car infrastructure and actively works against other modes of transportation. I'm shocked, really. Shocked.
I didn't say anything about it going defunct. That has to be one of stupidest attempts at a straw man I've ever seen.
I pointed out that it only ever carried material from one location to one other location, and that such a system would not be scalable to serving an entire city.
