The trains do make it easier! When I went to London, I couldn't believe how fast and easy (though expensive) it was to get to Paris via the Eurostar.Yeah, I know it’s several hours away. And if someone took a transcontinental flight twice a year to spend weeks in one neighborhood in London, I would also wonder why they wouldn’t ever use some of their trip to take a train to Manchester, or anywhere else in the country.
Off-topic but if you live in the EU or the UK, do people (minus Carrie LOL) take quick weekend trips to different countries frequently? With countries the size of some US states and high-speed trains, it must be really easy to travel and see a variety of things without everything being so spread out!
