Diamond Crossing Rule on DLS

Hi all,

This is just a simple post to let everyone know there's a new "Diamond Crossing Rule" that works with TRS2004 and the SP-3 upgrade by "Adamsloco" on the DLS. -> Kuid2:44272:90001:4

Like the v3 rule, it will only allow for protecting 8 crossings. I have used and tested it up to this limit and it works like a charm! The "stopped" train is released AFTER the last car of the "allowed" train passes the second signal of the controlled junction. SO NICE!

Think we all owe "Adamsloco" our highest praise for taking the time to modify the version 3 rule that didn't work with TRS2004 and SP-3.

Also, since I only use TRS2004, don't yet know if this version 4 rule will work with later TRS versions, ie, 06, 09 etc. But it just "might".

THANK YOU ADAM !!!! :D

That's awesome! I'll have to check it out, thanks!.

Many thanks to Adam for updating the rule.

Re Diamond Crossing

I've downloaded the Diamond Crossing Rule, but it doesn't seem to have any instructions on how to use it!

Can anyone help please?

DC Rule Set Up

Hi All again,

This is a quote that Adam Parker sent me on how to set up the "DC" Rule.

"Proto-typically, each signal at the diamond protects the *entry* from each
direction (even if there should never be a train from that direction.) So,
the North signal should be placed to stop any trains arriving from the north
from entering the diamond. The South signal should stop trains arriving
from the south. North and South signals are on the same track, but facing
opposite directions. The same is true for the East/West signals. The
signals for the diamond are generally placed close to the crossing track."

Also, you must first give the North, South, East and West signals a unique name by clicking on it. I do this in Surveyor. Then, start up a Session and Add the DC rule. Edit the rule and add your named signals in the appropriate boxes provided. It's self explanatory. Save this as a new session. You're all set! :D

I was going to give this a go, but I can't find anything on the DLS under useranme 'Adamsloco' or Kuid '44272' ????
 
Search the DLS for "Diamond Crossing" with "Title" and category "All" checked. Download the pack and both the rule and the test will download.

Tried upper case, lower case, space between, underscore between, dash between and no space between with same results.
 
The real rule is titled "don't post anything until you are awake." :o I apologize. "Crossover", not "crossing".

I found and applied the Diamond Crossing rule in TS2009. I appears to work. I say appears because I'm not sure I have used correctly.

My crude drawing

...............3
............N..\\
.................\\
............W....\\.......E
<==========\\=======< 1
>===========LL======> 2
............................S

A double track (1 and 2) mainline (each track one way) with a single track (3) crossing track 1 using a double slip switch and then joining track 2 with a single switch

Signal are shown as N, S, E, W

In the description the signals should be in pairs N-S and E-W. For N-S I can do but the mainline is signaled one way each way. So E-W are not on the same track. The next signal on track 1 is about 1000m further west.

A train approaching on track 3 never gets permission to advance.

In version 3 this setup worked except that the train on track 3 started to advance before the end of the train on track 1 had cleared the junction.

Is the only solution to go back to version 3 and place the N signal further away and hope the start up delay is long enough to allow the junction to be cleared before it arrives?

Or am I using the Diamond Crossing rule in the wrong place? Is it only for true diamond crossing and not for double or single slip switches?

OK, I'll have a stab at this...

From your ASCII artwork diagram (nice by the way) the approach side of the points on track 2 is not part of the diamond so W is just a normal signal protecting a set of trailing points and would work without the diamond crossing rule in the session.

I would put W as an invisible signal on the departure side of the points on track 1 and facing the points (i.e. protecting it from approaching "wrong road" traffic).

I suspect that the rule was not designed for single or double slip crossings and that may explain why the train on track 3 "jumped the gun" before the crossing train had cleared.

But I will download this rule and check it out.

I've continuing to try and make this work using various combinations of the Diamond rule, v3 and 4 as well as the Trigger Multiple Signals rule to try and hold the N signal red while a train is on track 1.

What happens is that while the train is waiting on track 3 at signal N, it will continue to try and control the switches of the double slip in front of it. All four are linked together using the Junction Link object. Even when there is a train on track 1, the train on track 3 still tries to play with the switches with the result that sometimes there is a derailment when the switch is changed while the train on track 1 is crossing it or the train takes the wrong track.

I thought that once a train is using a switch it is locked? Is the linking of the four together disrupting this? Is there a way to force a lock on specific switches while a train is using it via a trigger?
 
Some further ideas.

I think I read somewhere that a train tries to control two junctions ahead and only one behind. So, using a Junction Controller object, I made the junction at signal E control a junction further up track 3, (off the map) effectively holding trains approaching more than two junctions away from the double slip switch junctions. The first pass seems successful. Now see if any glitches appear with different timings between the various trains.
