I may have spoken too soon. I tested with Rush Hour enabled... my mistake. Then tested with NO time altering mods and my city ran for 45 mins with NO stuck vehicles.
The only common thing I can relate to stuck public transport is TIME FLOW mods (either Rush Hour or Real Time)
I feel like it may be an incompatibility between the altered time flow and unbunching, both Vanilla unbunching and IPT2

Could you please share your test game where the problem occurs?

Stuck vehicles the same,Your results are expected!

I cannot reproduce this problem. I tested the shared save game: the buses wait for some time at the bus stop and then depart. Both with and without Real Time. See this short video[streamable.com].

hi there, im noticing that my public transport seems to somewhat shut down in the middle of the night (after midnight) - some trains and some metros and some buses just stop and loading goes to thousands of percent and the rest just line up behind waiting for the front one to move.

During daylight hours - no issues.... only middle of the night.

same only during midnight

I have this issue at every time of the day. My public transports stays stuck at boarding, even with unbunching disabled.

me too I have to unsubscribe this mod

Can someone provide a small city without 100x of mods and 1000x of assets where this issue is occurring?

I have started a Vanilla test city, with only Real Time enabled. Played for about 2 hours upto a population of 5000. No issues. I will start to add mods one by one until there are stuck vehicles.

Thank you so much for your help. If you manage to reproduce the issue with a minimal setup, please share your save game! I am still unable to spot it.

Heres my Test City 2.0, much more basic than the last one.
I slowly added mods (got to 39) until I got a stuck vehicle, Metro Overhaul was the last one added. However the unstuck themselves at around 1200-1500% boarding, and it only happened a few times. After a while everything ran fine, im perplexed.

Oh by the way the city is in the middle of a death wave haha

Wasn't to do with Metro Overhaul, disabled it and still got stuck vehicles. Added all my mods (53) including Real Time and again, stuck PT vehicles. Then disabled Real Time, no stuck vehicles, game ran 20 mins on 3x speed without a hitch

Okay, I dropped the Automatic Bulldoze mod - it caused a bunch of exceptions because of missing assets.

I loaded the game and ran it for 10 min at 3rd speed. The buses are moving en-route as usual. Sometimes they stop and show boarding progress up to 300% with an "unbunching is in progress" state, then the buses move on. I guess that is intended behavior.

Where should I look at or what should I do to make them stuck?

I think this happens when the vehicle is full. I changed the train capacity to 3000 passengers and no stuck so far.
