Distant signal

[Per Olsen]

Hello.

Found version 2018.1c today. Is this function active now?  Did not find it in the doc…

Regards,
Per.

Hello again.

I found "Vorrangssteuerung" in the doc for 1c now.

It is correct that I do not want D to enter C while there is a train running from A via B to C. 

But also, the most important thing, is if I could somehow activate the C (like I can with B) from A when the train is still in A.  Can I do this?  In that case, the distant signal will also show correctly.

Best regards,
Per.

Hello again.

I tried a lot of things, with no success. 

When the train is running in route A, I have no problem to activate route B (if free).
In the same manner, when the train is running in route B, I have no problem to activate route C (if free).
But I also want to be able to activate route C, if both C and B are free, when the train is still running in route A.

If so, the signal in route A will say that route B is free, AND the distant signal will also tell if route C is free.

Best regards,
Per.

Hi Per,


I think I misunderstood your problem. If I understand correctly you have the routes A then B then C. I understood that A and B are parallel and both ending in C. So the FDL won't help you.


But I still don't get the point where the problem is. Maybe you can show me a quick drawing. That will help to understand it.

Hi!

No, the 3 routes are in sequence.

The train runs through route A first.  Route B starts where A ends.  Route C starts where B ends.  So the train runs from A to B to C.  When the train is travelling through route A, the signal by the end of A shows if B is free (and activated).  If B is activated, the distant signal near the end of A will show if C free and activated.

Per.

Hi Per,

there's the same question in the French forum. So I will write a short description and translate it twice. That will take a while because I'm in holidays.

Hi,
I think this problem is similar to the SBL signals used on PKP. Look on the simulation http://www.transportszynowy.pl/sygnalizacjasbl.php#4ust (lower picture).
So, the SBL signals depend on the occupancy of the tracks ahead. To replicate such signaling system in WDP I use some dummy symbols in a place of real semaphore (little green/red dot) to comply with requirements of WDP, and separate symbols for the signals controlled with the dispatcher according to the occupancy of the tracks.
Greetings,
Andrzej

Hello Andrzej!

Thank you for your answer.

Yes, I know that I can work around the "problem" using dummy signals etc.  I have done this before   But it would be much easier (in my case) just to be able to make route C active (as I can with route B) when the train is still in route A.

For now, I await the description from Stefan.  Thank you anyways!

Best regards,
Per.

Hello Per,

you can't make C active when the train is in A. That's simply not possible. The description I wanted to write is how to set the far signal when the train is in A and B becomes activated.

If that is not what you want then make a long route from A to C with a partial route to B.

[Per Olsen]

Hello Stefan.

No, the long route is not the solution, as the distant signal always will be green, as the long route will not be activated unless the entire route is free.

But it really IS possible…  I tried to put in route B the "Check next route within tour at contact" as an RMK from inside route A.  It shows up with yellow background, to indicate that the RMK is outside the current route (B).  It actually does work.  But I do not like the yellow background…

Regards,
Per.

[Stefan Lersch]

Hello Per,

I never tried that before. As you already said yellow is just a warning. If that works leave it that way. Markus sure will not change the yellow background to white because as you already wrote the contact is not within the route. But very good - you found a solution!

[Per Olsen]

Hello Stefan.

I do not mind the yellow colour but the colour tells me I am doing something I should not do so if there is another solution, it might be more correct to use that one.  Well, I will test this out for a while, see how it goes.

Best regards,
Per.

Hello Per,

yellow is just a warning. If it's red you are doing something wrong. I also have some routes with contacts with yellow background. That's because I check if there's a train on the track next to it. So this is fine!

[Per Olsen]

Hello Stefan.

Yes, I do the same in some routes.  Thank you! 

Regards,
Per.
