[2.0.76] Trains randomly pausing at waypoint stations

I can't figure out the logic of this yet, but sometimes, trains with a waypoint in their orders will momentarily pause at that waypoint (and not at/next to a signal)

Other times, with the same train or the same waypoint, there is no pause...

I can load up the same saved game repeatedly, and in one particular holding area, the next 4 trains to arrive will always pause, the 5th one will not pause, and the 6th one will pause.

These trains all have shared orders, the waypoints are all copy-pasted from each other, each lane has the same signalling, etc...

Something strange seems to be going on.

Location of holding area in question: -272.9,2004.3

First 6 trains all arrive within 30 in-game seconds or so.

the save isn't available

from the description an hypothesis could be something like : the waypoint has a condition about something like cargo full / empty , and not all the trains are loaded the same

there are other cases where it's difficult to predict if the train will stop for 0 second, loosing all momentum, or if not, that may be one of those more trickier one too ^^

I have tried twice to add the save - each time the preview window shows it properly added but it doesn't show up in the post...

None of the waypoints have any conditions - if they did then they would not be waypoints.

Also, for whomever moved this from Bug Reports to Gameplay Help, I would appreciate if this can be moved back, as this is to my mind clearly unexpected and unpredictable behaviour - classic signs of a bug.


Thank you.

So far you have not shown anything.
