My new double-double 4way and standard 3way.

looks interesting, but are you sure those PBS exits want to be 2 way? 2 way would assume it can choose either exit and still end up where it is going.

not that it matters for PBS anyway, but if you turned off NPF, things would definitly start to get lost.

good looking design me thinks

They should be 1 ways. I made A LOT of changes to it, and those were left over from an earlier design.

I'm also missing signals on the entrances and exits to some tunnels. I had ~50 trains going through this with 4 stations just beyone the edge of the screen shots. I found that the stations were my weak link.

here is my newest version of a 4way junktion (inclusiv priority)

what do you think of this doublelane 4way junction?

The two biggest high capacity junction of my map.

4-way junction

3-way junction

I never understood why junctions should be that symmetric. Everywhere I look in those topics most junctions are highly symmetric. I never use symmetric junctions, because symmetry is a useless extra constraint on the lay-out: A junction need not be symmetric to work properly.
I always have exactly those connections which are necessary. This has the advantage that it is cheaper, you have more space for the connections which are necessary and it reduces the chance of misrouted trains. I like to play in mountainous maps, so the limited amount of space also poses a restriction on what I can build. That's why I play it that way: It's more challenging.

It is all about eye candy (and copy ease).

I do that too, but sometimes I have trains planned to go in certain directions so I make those lanes some years before I actually need them. It's just to make it easy because you don't have to reinvent the whole junction.

it is worth noteing that sharp turns kill train speed. try makeing them less sharp to make juctions work better.
also avoid long tunnels and bridges if you can.

Dear King, I DO always duplicate tunnels. And there's no high-speed bridges under 3 tiles

The reason for short bridges and short tunnels being preferable, is that the signal sectors can be kept short, so you dont get a queue while a train crosses a long bridge/ goes through a tunnel. The most often used is a 2-line bridge/tunnel, with a signal on the slope, 2 tiles of bridge/tunnel, and another signal on the other slope.

Well, here is some of my crossovers and junctions:

Giant 8-way crossover (1.53MB)

The idea with this crossover was that no trains need to drive over junctions in the crossover, but it is really huge and expensive to build (it uses about 1/5 of a 256x256 map).

Insanely giant 8-way crossover

This crossover was made with three squares space between the tracks, so it is possible to access any tracks by building tunnels under the main tracks (see this picture).

The crossover was made on the middle of a 2048x2048 map, covering 128x128 squares of it.

The pictures shows hardcore testing of the crossover with 280 trains (each with 4 eurostar engines and 24 armoured vans). Every track is tested with 5 trains, all 8 directions have 7 tracks each way...

Now over to my (more or less) normal crossovers and junctions:

A four-way crossover with PBS

An irregular crossover

Main station entrance

Main station exit

...by the way, God bless PBS!

I want PBS but I cannot compile

Have you tried the latest integrated nightly? If you use Windows, you can just download the Windows binaries.

Great, thank you! The new semaphore gui is great, by the way

its not new, infact its older than PBS is. unless you are saying its been updated, but then i'd know about it.
