I’m someone who often takes trains when I can, over planes. The scenery is sometimes nice, but in the NE corridor it’s largely just backyards and tree-lined alleys through industrial areas. More pleasantly, I don’t need to interact with TSA, I don’t get the weird derealization that comes to me in airports, I don’t get dehydrated or pressure headache, the seats are larger/comfortable, the internet is faster/cheaper, and finally, the carbon emissions are fewer per passenger-mile.
edit: and when I’m restless the train has much more space for light exercise or walking.
