[boskid][0.17.79] Train very occasionally does not pull all the way forward into Rail Chain Signal

[Syyiailea]

I've got a big train based smelter. Problem is, I measured the "waiting" section far too exactly to the length of my trains. Now, for some reason, about once an hour a train pulls into the waiting station a few inches too short, and blocks the main railway and all the other trains trying to enter. So far as I'm aware, it isn't my inept railway building that's caused this because the setup works 99% of the time. Now my only recourse would be to tear up the whole thing and rebuild it a few inches to the left to lengthen the waiting area runway.

It looks that locomotive properly pulls up to the signal, it is the last wagon's position that differs a little. I've managed to get reproduction, train will sometimes fail to release segment on its back so it may be rolling stocks coupling distance issue.

Reproduction attached for whomever will be trying to fix this "Minor issue" in future. This rail segment is really tight: it has a length of 41.012 while train is expected to have a length of 41.

Ayyyy! Sorry for my very non-technical analysis of the problem, but it's awesome to know that it's been added to the list and that it wasn't just that I had forgotten to place a signal somewhere. Cheers!

This issue looks to be fixed by a fix for a 81102, so i will move this to duplicates (even when it was reported before).
