If the city is already full of subways, the job should be easier, not harder - now you only have to tunnel your way to the closest existing station and then extend the line.
- crazygringo 5y agoIf only it were that simple. So now your supposedly "fast" direct train is stuck waiting behind a local subway that makes every single stop, because there's only a single train track in each direction. Believe me, if the job were easier, it would be done everywhere already.
- Symbiote 5y agoA frequent, local subway can be as fast as a "big" train plus a connection. From Copenhagen Airport to the centre, by ordinary metro, is 17 minutes. I'll take a subway connection over a bus any day. Anyway, this comment suggests the reason it's a problem in the USA is regulation. (I can't speculate on why this happened, I don't see which political group is supposed to benefit.) https://news.ycombinator.com/item?id=27944624 https://news.ycombinator.com/item?id=27944624
