Well, how to decribe it... Simply put: you don't end up in a clean and cozy Japaneese town, there are few shady taxis who will be ready to propose you a comfortable trip back for around 200-300$. There is no convenience store open 24/7. If you're unlucky to end up there in the winter, then it's probably -20C outside. There is one 24/7 ATM corner which is mostly occupied by the local homeless people – so the ONLY warm option left is to go for a shining 24/7 slots machines/gambling place and try to gamble what you have for a taxi money or just to kill time. I once spent a night like this in Tver, gambling ~10$ what was left in my pockets all night with minimal bets.
Cockfosters was proper despair, and Mordor (or Morden) well... don't.
What took the cake though was flying back and arriving at Stansted after midnight and waiting for the 5am escape back home in the depths of winter.
London offered many memorable evenings for those silly enough to party in the city a while back.
Not drinking so much is probably a way to avoid the despair, but where is the fun in that?

My route home is via commuter rail so I don't have that luxury. I wouldn't possible know what it is like to wake up after a few beers and find myself on the last train of the night, four stations past my stop, but rumour has it that the night bus network is pretty good at getting me^H^Hpeople home, even if the wait can be cold, so long as you've not actually left London. Or Uber.

But if you don't wake up til the end of the line, it's probably pretty much like in Japan, except less clean.
That said, France is the same regarding commuting trains, oversleeping in Paris's RER will lead you to pleasing but pretty far away towns.
Did it once, and spent about 5h visiting the sleeping town by foot to mark the occasion. Did it again in the midst of winter, and the staff allowed me and the two other blokes to stay for the night in the next departing train with the heating on.
Spain had trains going well into the mountains as well. I can't imagine how it goes for Russia, China and India.
That’s a notably kind and humane gesture in the midst of winter.
You could definitely take a regional train passing through the city, for two hours to somewhere like Magdeburg, but you don't get on those by mistake as they run infrequently, only stop at the bigger stations, and have separate platforms.
Høje Taastrup is a large suburb at the edge of Copenhagen, and the end of an S-train line, but anyone who lives there will know an intercity train is faster. Trains to Aalborg stopping at Høje Taastrup leave at 00:50 and at 02:50 tonight. The other suitable intercity and regional trains overnight are to nearer places, 150km or so.
Daisy: [answering phone] Hello? Oh, hi, Mike. Yeah, he's here, I'll just get him.
[to Tim]
Daisy: It's your boyfriend.
Tim: He's not my boyfriend.
[picks up phone]
Tim: Hi babe.
Mike: Hello Timmy!
Tim: Where are you?
Mike: Err, Sheffield.
Tim: What are you doing in Sheffield?
Mike: Fell asleep on the tube.
Tim: The tube doesn't go to Sheffield, Mike.
Mike: Yeah, I know. I, uh, must have changed at King's Cross.
Also not a despair place. But the point is you can go far. Same must be true in Japan.
Or, if you're heading to Indiana, the NICTD South Shore Line can take you all the way from Chicago to South Bend.
