a little signalling help

so, it's probably simple as. But, I'm wondering how I can place signals so that the two lines in the highlighted area of the below pic can't be crossed by 2 trains at once. I guess the same principle would take place in any general crossover. But signalling really is not my Strong Point. My route's are built for AI running, so they need to be able to avoid each other here.

Thanks in advance.
 
Boat's ATLS system has been developed to overcome this issue. Here is his website which includes links to the assets and tutorials for setting up the crossings:

There are other ways using linked invisible junctions but I think the ATLS system is the best option.
 
The easiest option would be to just add the "Diamond crossing Rule" and tell it the signals to control at that junction. It works by only letting one train at a time into the selected area.:wave:
 
Another option is the Trigger Multiple Signals rule. You would place triggers on the two tracks that cross, set the trigger radius to equal the distance to each signal to be affected, then enter the trigger name and signal name(s) to be set to stop when triggered. Beware: some signals don't seem to work with this.

Hi,

Actually, my ATLS system won't do this situation properly as it requires switching control of the point. ATLS is OK for level crossings but not junctions.

Similarly, ASB Crossover which is on the DLS will almost do it, but again there will be conflict with Trainz AI.

There are some methods on the DLS but the only kit of mine which is specifically designed for this is ASB Turnout.
It's Payware I'm afraid... (but very reasonable :cool:)

Actually, his systems other two systems on his site would work quite well. IF, you are willing to buy the ASB DTT system, this one is the best as it is designed specifically for double turnouts, amongst other things I discovered. ( I HIGHLY recommend it, it is well worth the few bucks it costs.) If not, then go with the ASB Crossover. That one is Freeware. After thinking about it, I fail to see how the ATLS system would work. If you made it work for this, can you let me know how? I am now curious about how this is done.

Cheers from across the pond,

You can also use "Trigger Multiple Signals Rule"

Just for info....

Most of the other systems which will do this turn a signal red when they want to stop the other line. This can result in SPADS if a stopping train is close to the signal when it changes. One of the advantages of ASB Turnout is that it keeps potential last minute signals red and only 'allows' trains to pass if its clear.... So no SPADS, (hopefully!)

Nope, No SPADS at all. The AI just runs the DTT system to perfection now. But, I am about to post a question on the Payware thread about not dropping commands again.

Sorry should have been more specific and said ASB rather than ATLS. Used ATLS as a general term for Boat's excellent assets.

I read ya loud and clear. I've done things like this too. We are all human after all. I whole-heartedly agree, they are great assets. Made my sim experience 1000 times better (10 x 10 x 10 = 1000.) I like the Payware system the best of the three. I bet I could get away with reducing the use of the annoying red trackmarks to a ratio of 1 - 2 for every 500 baseboards( I crunched numbers for this ratio. I don't have a map that large.~~~~~ yet.)
 
I've used type 08 signals for situations like this with good results.

I place the signals in the following locations, using the picture above as reference:

Left hand side signals about 4 squares from your junctions

Upper branches, about where the yellow spline points are.

The lower straight tracks about in-line with the upper signals.

All signal face away from each other and are used to protect the intersection.

With the signals far enough away, this prevents trains from running up to the junction and crossing over the tracks, which causes other trains to go through them because there's no collision detection.

Using the latest signals, such as those by Justin from Jointed Rail, there appear to be very few SPAD issues. Trainz AI now slow down way ahead (sometime annoyingly so) before they get to red signals, so this doesn't appear to be too much of a problem anymore.
