Hi,

I've been playing with friends quite a lot on net and we found quite annoying bug with PBS.

Sometimes, the PBS doesn't want to allow the train to enter station (terminus), although there is clear path (see attachement). I did try to enable showing of reserved path and it shows no reserved path in there either (should be on ss as well). Adding two-way PB signal in front of station seems to remove this problem, but I'm pretty sure it isn't required to use, as I used it many times without and it worked normally.

Now, I use 0.7.0 beta2 and it "seems" to be fixed. However, better words may be: I'm unable to reproduce it. I've been searching in new beta patch notes and even on bug report and haven't found anything on this. It's possible that some kind of side effect of another bug fix fixed this, though.

However, as I have only very little knowledge of pathfinder in this game and my debugging skills are non-existant, it would be great, if someone with better knowledge would look into it.

About the save: station name should be something like Great Bennbury Forrest (?). There are four two-way PBS in front of station, if you are running 0.7.0beta1, removing those seems to trigger the bug. Also note: this is friend's save as I wasn't able to reproduce this bug and the tracks might have some flaws.

Thanks for help!

Just guessing, but I think that the livestock train doesn't want to go to that station and is looking for the shortest route to a point to turn around. Going straight ahead into the station is the shortest route to turn around, but is currently occupied. Therefore, the train is waiting for the platform to clear.

check the setting "yapf.rail_pbs_station_penalty" (default is 800)

if you reuse a config from older versions of the YAPP patch, this setting may be wrong.

Oh, yes, I had there 3000. However, is there any way to test it in that save? If I'm not mistaken, savegame also remembers the settings. If so, is there any way to change this value directly?

Thanks for help!

yes, you can change settings from the ingame console.

I guess it is the "setting" command. Well, I tried (the command was setting "pf.yapf.rail_pbs_station_penalty" 800), but the problem still persists.

edit: even tried to change the layout to be little less "messy", but that didn't work either.

well, then you obviously messed around with even more pathfinder values. you have to fix those, too.

Only thing I did in openttd.cfg prior to this was changing the small font size, so the values should be default (unless there was major change in values between 0.6.3 and 0.7.0). However, the strange thing is, that I've tried to build similar track, which worked perfectly. Tried three different layouts on the first track and the 3rd and 4th platform are left free most of the time, while the trains are waiting for free platform.

Set pf.path_backoff_interval to something really low. For more, try http://wiki.openttd.org/wiki/index.php/ ... ch_options

Don't. I fail to see any relevance to the reported problem.

I tried to reproduce the problem with current trunk using the savegame, but wasn't successfull. Everything seems to work just as expected. You might try updating to beta2 in case the behaviour was caused by any of the fixed bugs.

True. When I was playing some precompiled version of cargodest, it used old revision which had exactly the same train pausing problem. Now it's gone and trains run smoothly.

Thanks for the help. I'll let you know, if this would happen again.
