[Bug]: Jammed trains due to train speed adaptation #613

Closed telk5093 closed 10 months ago

telk5093 commented 10 months ago

Version of OpenTTD

jgrpp-0.55.3

Expected result

No traffic jams for trains behind proceeding one.

Actual result

Trains behind the first train are jammed when:

  1. train_speed_adaptation is on
  2. There were lots of stopped trains and the first train just is started to go.
  3. The first train move forward fastly, while the proceedings are jammed due to the slow speed until pass 1~2 signals.

Steps to reproduce

Take a look the blue trains of the company #11 around 2451, 5326

(Just for note:) JGR said in Discord:

I'm not that original author of it, and don't use it myself, but it presumably works nicely with particular playing styles

This should be somewhat improved in the next release.

In the case of this save the uneven signal spacing does not help though. e.g. where Company 11, Train 42 is.

uneven signal spacing does not help though.

I also commented the exact saying to the owner of the company #11. And sounds nice that improvements! 👍
