Station signalling help required

Post by Jishm »

Hi all.
Got myself onto openTTD yesterday having not played this game since I tried it hopelessly at my uncles as a young kid! Anyway, I read a load of tutorials and stuff and soon got the hang of it and have carried on developing up to this stage. Basically in the screenshot provided I have my big station which takes in Grain, Livestock and Steel, and then provides Cargo and quite a bit of it! I recently modified some of the incoming track from the right due to a recurring problem, and in the process messed about with the signals, and now have a problem. On either side of the station there are Combo signals, and then each rail after that is either coming in or going out, with Entry signals on the in tracks and Exit signals on the out. However this isnt working, the trains all want the same platforms and I dont know what to do, help!

Given your track layout I suggest to
- adjacent to the station replace every signal by a path signal which faces the station
- and place a single one-way path signal where the tracks leading to the station end

Combo signals are there one of the only really wrong choices.

and http://wiki.openttd.org/Signal

Please in the future also
- attach your screenshots to this forum. The photobucket scales your image so that every signal is undiscernible - very unhelpful when discussing them
- use png as screenshot format. Also jpeg blurs colours, making it also very hard to distinguish signals. OpenTTD has an in-built screenshot capability which uses png as default.
I couldn't decipher the type of a single signal in this case.

It's a really big problem when you use presignals on both sides of the station. It's possible that 2 trains from both sides of the station will set their courses to the exact same line, then one train will block that side of entrance to the station.

In this case, I've seen path signals used.

With this kind of set up, trains from either side will reserve their path far enough that trains from other side will never try to occupy the same line at the same time.

Cheers for the help and apologies for the poor screenshot, I should have checked the board ReadMe first.
I took action and changed my setup to the same as the screenshot Sylf provided (which is pretty much the same as planetmaker suggested I think), and it now works, although some trains decide not to turn around, and instead go out the bottom end, through another platform then out the top. Im guessing its because at the top end originally the signal would make the train stop due to another train approaching, but it just seems like a waste of time and energy overall to loop back round (see screenshot)!

Nope, in your screenshot is just a straight piece of tracks missing, leading from the platform to the exit.

Yes, quite. Indeed you're just missing a piece of track:

Ah, so that's why I couldn't figure out what was wrong... I thought the train was going in the other direction... :D
