After encountering everything from a taxi driver in NYC who didn’t know where Grand Central Station was, to a recently hired physics professor with a PhD (Univ. Cal. Davis) who didn’t know what a partial derivative was, someone having a particular job title means zero to me. It just means that someone, for some reason, is paying the person to do <job title>. But this guy didn’t do too badly, after all.

a taxi driver in NYC who didn’t know where Grand Central Station was

You mean the post office?

No, I mean the largest train station in the world, the central rail hub of the city, a famous landmark and tourist attraction. The official name is Grand Central Terminal, but nobody calls it that (usually just “Grand Central”).

I was curious about the "largest train station in the world" claim. I figured there would be bigger ones by now in India, say, or China. Sure enough, there are different metrics by which different stations can claim to be the largest. Nagoya Station in Japan, for instance, is the largest in floor area. Shinjuku Station, also in Japan, is the busiest by daily traffic. The Gare Du Nord in Paris is the second busiest by this metric. Apparently Grand Central is the biggest in platform capacity.

Anyway, back to the point.

What about volume? Grand Central has a high ceiling.

This is why I love Hacker News lol
