first of all - hi, im kinda new here
so far i've been playing the inefficient way, simple terminus stations no mainlines one train per track etc. (sic!)

now i've decided to tweak the way i play, ive introduced mainlines and connect industries to them, but still have problems, these related to breakdowns and trains jamming whole mainline

i tried to add second track to the mainline and hoped to divide them into sections, when a train breaks down inside section, other ones will pick free route, but so far without success, i.e. if both tracks are free and two trains approach the junction, only one passes it and the remaining one is waiting for the junction to be freed ( although the second track is free )
i've heard that PBS is the solution but i cant figure that out

thanks for suggestions

the signal is red because both lines are connected. so one train uses the part of the junction for its own. A green signal would maybe cause a crash (letting the waiting train crash into the train in the junction)

I assume you're using a recent version of the MiniIN? You need to go into the configure patches menu -> vehicles, and disable YAPF. YAPF is the new pathfinder, which is currently a work in progress in the official nightlies. PBS is no longer supported, and uses the old pathfinder, but was brought up-to-date just for use in the MiniIN, so they're not compatible.

Personally, I always play with breakdowns off. You might find a few designs around here for coping with them, but you'll probably find that when dealing with large complex networks and lots of trains, the most practical solution is just to turn them off.

Rinnsal: they're PBS signals

you can do the same thing without PBS using a junction something like this

@sc79:
I've compiled yesterdays MiniIN.
Seems to work with YAPF turned off. Thanks, at last a step forward
I spent so much time trying to cope with the breakdowns that I cant just turn them off ( for now? ).
Maybe when I advance to even more sophisticated designs and don't give up first.

@bobingabout:
Check out this situation:

Train A is stopped so it blocks the Path A track.
Train B approaches junction, but unfortunately it still picks Path A and jams the next junction.
Thought it is caused by Signal S being green, but after removal trains still pick the Path A.

After turning the YAPF off, trains keep choosing the Path B all the time.

As the PBS is not supported outside MiniIN I'm still interested in solving the problem using traditional way.
Currently I'm checking the presignaled "Track switch" design provided in one of the "crossings"
savegames found on the forum.

PBS does not work in MiniIN with the YAPF pathfinder. It does work with the NPF pathfinder - but that has performance issues on large maps with hundreds of trains.

Train B picks path A because the signals are one way. Change them to 2 way and train B should pick path B.

2 way signals provide a choice. 1 way signals make trains take the quickest route regardless of red lights.

As you're a beginner, I would seriously suggest you avoid breakdowns=on until you really understand all the subtleties of signalling...ok, not ALL of them, but get the basics (I'm still learning after many years of playing!).

I have no problem with that sort of setup, using plain (one-way) signals and with YAPF, NPF or the Original PF (yapf and npf off).
- (Im sure oneway signals shouldnt work with NPF/YAPF off, so Im going to assume its either deliberately been changed, or a MiniIN bug/feature) -

However, trains wont pick path B unless the first signal in path A is red, since they cant (yet) look more than one signal ahead.

You're probably right...also, I haven't used YAPF so can't be sure how it behaves...

Well, I was nearly right!

the picture i posted isn't exactly what i'd do, i used a picture of owens site.
