You're supposed to put your phone on airplane mode in a train or subway too, but most people don't: https://pocketnow.com/airplane-mode/ https://pocketnow.com/airplane-mode/ The problem is significantly lessened for trains vs. planes though because you're traveling an order of magnitude slower and hence you switch cells an order of magnitude less frequently. Also many commuter rails run alongside major highways or boulevards, where the cell systems are built assuming lots of cell handoffs at roughly highway speeds. If enough people used high-speed rail to overwhelm the cell system we'd probably see announcements to put phones in airplane mode there too, but very few folks will travel long distances at high speeds on a train.

That article sounds like a bunch of hogwash to me. The CTA in Chicago specifically has cell phone infrastructure in the subway lines, and that predates that article. https://www.transitchicago.com/cta-to-bring-4g-wireless-service-to-subways/ https://www.transitchicago.com/cta-to-bring-4g-wireless-serv...

> You're supposed to put your phone on airplane mode in a train or subway too, That's a pretty insane claim in most of the world. Lots of people expect and enjoy full coverage on train or subway rides. I work at a carrier and the signal strength and cell capacity on trains are part of the top metrics we use to benchmark the quality of our network and the customer experience.

  > You're supposed to put your phone on airplane mode in a train or subway too, Why would you be expected to do this when we don't require drivers to put their phones in airplane mode? I get that US trains are slow compared to other parts of the world, but does the Autobahn require airplane mode? Doubtful since my German car happily connects to my phone in multiple ways.

Millions of people travel long distances on trains: 353 million/year on the Shinkansen network, 1.5+ billion/year on China high-speed rail, 110 million on France's TGV. These passengers use their phone without overloading the cell networks.

The operator can just pay for the high speed handover feature license ;)
