In general trains stop in more central locations than airports, which usually get sited far away from people who might complain about the noise. And if you set up the system to do so, trains can stop multiple times within a metropolitan area for easier access. Tokaido Shinkansen trains call at Tokyo, Shingawa, and Shin-Yokohama; the ICE stops at Berlin Ostkreuz, Hbf and Spandau going west, or Gesundbrunnen, Hbf and Sudkreuz going south.

True enough.

I live almost equidistantly from three international airports, all, nominally (that is without traffic) about 75 minutes drive away.

The closest main train station is a 15 minute bike ride away or a 10 minute drive away (without traffic). Funnily enough the local train station is slightly further away both by car and bike.

True, takes me 15 minutes from door to (train) door and I don't have to endure the usual airport security shit and calculate a buffer time of a minimum of 60 minutes, which can be significantly longer, depending on the airport.

Sure, not every country (notably the US) offers such privileged amenities, but where a good train network is available trips up to six hours are definitely doable, if not preferable.
