Problem with 'small trainstation and to many trains

[DijkeMark]

Hey guys,
I just started playing OpenTTD, must it is awesome!
But now I getting used to the game and I want to build bigger stations and stuff.

I got a 4 lane station right now, but some how my trains sometimes block eachother.
Also, sometimes some trains leave the station from which they came and go back in the stions in a different lane because there they have room to get back on the track to the next station.
I am currently using entrance/combination and exit signals, but I don't know when to use them right.

I looked at the wiki's but I don't really understand them.

See the attachments for the screenshots.
As you can see, trains are blocking other trains in the station and stuff.
This idea worked without problems when I still had 2 lanes, but since I got 4 it is dramatic.

Can you guys give me some help on how I SHOULD be building this station? (Hope you guys can give me examples xD)

Thanks in advance,

Mark

simply replace your path signals with a entry signal and it should work.

simply replace your exit signals with path signals and it should work.

General suggestion - you can join multiplayer (without starting company) and check typical constructions.

Pikka's suggestion is the best here. There's no way you can make such a station work without path signals. Personally I'd make the outer platforms one-way, so that there's always at least one platform available for either direction.

Okay thank you guys.
Hope I can get it to work now. xD
