Almost every big city has problems with trains running late or being cancelled, I think it's more common than you might think. I live in Stockholm and before the pandemic (when I commuted daily on the pendeltåg and before that, with the roslagsbana) I agree with you it could be pretty bad (there were several days where they simply closed off the trains and everyone had to squeeze into much smaller replacement buses, and a few times when even the replacement buses didn't run - you had to find a cab to get home... and good luck finding one.. but at least the government covered the fee if you could show there was no other alternative at the time) but having lived in a few other countries, I've seen all sorts of crap like that as well, and other things that nearly never happen in Stockholm are quite routine at other places, like stations and trains where passengers squeeze like sardines, buses so full some people go hanging outside the doors (the bus driver is supposed to close the door, ofc, but the situation is so precarious they try to let in as many as they can as they know how terrible it is to be just left behind because there's no space), robberies on night buses (which to my knowledge can happen in Stockholm but are extremely rare)...

There are almost certainly very few cities in the world (if any) where residents who need to use public transit day in and day out think it's a consistently great experience.

The leaves+water and pressure forms an extremely low friction surface that risks derailing the trains and happens all over the world.

Some trains have special brushes or water jets to clean the tracks

Dublin’s light and intercity rail is affected by leaves too. It’s a major problem for rail adhesion in autumn.

London's the same. Here is more info from Transport for London: https://madeby.tfl.gov.uk/2019/10/07/leaves-on-the-track/
