Why's everyone got a downer on the tube? .... spent many a happy day as a kid with a day-rover ticket visiting the farthest reaches of the system ...as a 12/13 year old on my own. Always use it on the odd occasion I visit my old home town for an exhibition or some such .... lots of trains, far and away not the dirtiest of public transport systems ... and I grew up with the racket they make so doesn't bother me 🙂..... there's plenty of cities would give an arm for a system as good. Like so much in the UK, having invented things, or been a very early adopter, means we are sometimes constrained when it comes to matching other place's showcase transportation ... but beware of PR ... not all of Japan's trains are swishing along at 200 mph ... their local systems that most use struggle to match ours ... and those wonderfully efficient Germans have a notoriously unpunctual train service 😀
