Problem/suggestion with PBS

In the attached image the coal platfrom is of particular interest. Trains to it arrive from A and B.

Trains from A are to leave to C, trains from B are to leave to D.

As you can see in the image The train reserves tracks until the end of the PBS block without looking where it is supposed to go after the station order.

This results in both routes reserving a straight piece of track, reversing at the one way signal and leaving to the other direction through the wrong exit.

Is it possible to make PBS take order after stations into account when reserving a track through a station they are supposed to stop at ?

Yes. Put a signal after the station.
Or switch the running direction of the A->C (to C->A) so all trains go through the station SE->NW.

a) if both trains arrive simmultanously theyll block each other if there is a "buffer" signal between the two entrances you see

b) reversing one running direction could be done but if i just not want to or are in a more tightended situation where its just impossible it should be possible to make it work this way too.

edit: As this seems persistent could it be moved to the Suggestions forum ?

That's just impossible.
Trains can't look beyond the next order in the list, so it doesn't know where it has to go after that order.

You can *always* reverse the direction of a loop of track. Just reverse all the one-way signals.

no s***, but what if dozens of other trains are using a particular track in the same direction.. Anyway this is OT posting, the topic is:

Can PBS be made to consider more than only the next order if said next order is stopping within the PBS block in question ?

It could, but won't, for that would be far too much work.

and the extra signals wont hurt so there is no need.

:idea: You need to make the block containing the coal unloader non-pbs. With your layout that would prevent exit from the wood platforms at the same time any coal train was in the coal block, so don't connect the coal exit track directly to the wood outlet, instead loop it round in parallel, joining in after the next signal, and remember to add a one-way signal on the link to separate the blocks. If you can afford it extend the parallel link further to take a complete empty coal train clear of the platform, for when the wood line is blocked as a coal train leaves to D.
