Passenger rights are very good in the UK. It's easy to claim Delay Repay, where you get 25% refund after a 15 minute delay, 50% refund after 30 mins and 100% refund after 60 mins. Other train operators are obliged to help you get where you need to go if the company you intended to travel with has cancelled your trains, or you've missed a connection due to a previous train you were on being delayed.

I've had the last train out of central London for the night cancelled at about 1am and you can just message the train company on social media and they'll pay £100+ to get you a taxi all the way to somewhere like Cambridge.

Also, not sure how it is in other countries, but in the UK, everything is entirely open data. You can go to a site like https://map.signalbox.io/ to see a live map of every train in the UK, and sites like Realtime Trains let you get all the details about every train (eg. https://www.realtimetrains.co.uk/search/simple/gb-nr:KGX)

Yes, you'll get a refund. But that isn't much use to you if you need to be in a certain place at a certain time.

Some operators begin at 30 minutes

And some operators love to ignore their obligations

Our protections are good on paper but in reality quite poor. London is of course better than the rest of the country though.

I don't consider having to message a faceless social media team on "X" to get a taxi refunded good customer service at all. And they are definitely pushing for you to pay first and then get a refund, which is not in the spirit of the contract. My mother doesn't have "X" and wouldn't know where to start
