Train collision

[kiv@vftronic.no]

Why do trains sometimes (1 out of about 20) choose a route that causes a collision?
Image ok.jpg shows tours for train as setup in tours1.jpg and tours2.jpg
Image error.jpg shows that both trains choose the same route and a fatal collision occurs.
Does anyone have any tips for what cause this serious route selection error? What mistake is done in my configuration?(tours1 and tours2)

Hello Ivar,

I cannot tell from your screenshots where exactly the problem is, but I can explain the theory. WDP uses switches or signals ("Magnetartikel) to safeguard against crashes. So if you have two routes between which a crash has happened, you need to add one such item on both routes which is included in the recording of the route. If there is no switch which both routes use, add a signal somewhere along the route and modify the recording of both routes to include the signal. From then on, whenever one of these routes is being used, the other route cannot be started, and you are safe from crashes.

Have fun!

Hello Oliver L.
Thanks for your advise, but I assume there are enough signals to avoid collisions in my system.

The system is block controlled, train A needs to travel 3 blocks 24,29 and 59, Train B 4 blocks 54,55,57 and 59 before the collision occurs.
By checking the tours I discovered that "Check next route" for Train A was set to 59 and for Train B to 59
I modified Train A to 24 (last block before turnout) and B to 57 (last block before for turnout), and will start a new test by running 3 trains. See enclosed image.

Hello Ivar,

that won't change anything...

Can you select the two routes and take screenshots of them so I can see where the conflict happens?

Hello
Oliver

After my modifying today the trains run for 2 hours, maybe just luck
enclosed actual tours, where problem occurs (totally 3 times), in approx 1/2 hour or less continuous driving.
There are some limitation of adding files by this forum system, if you send the e-mail address it will be more easy to exchange info. My system is also available by AnyDesk

Hello Ivar,

that's not quite what I need. Place a train on the starting field for the one route. Click on it and on the stop point for this route. You should have the route highlighted. Take a screenshot of that one and repeat with the other route. With that we can check and see where the problem lies.

I have on average 6 to 12 trains running in automatic mode, and whenever I do have a crash I can find out where I screwed up in my programming, so I am very confident that it is not a problem of WDP.

hello

Agree it is not a software issue, but I don't see my own mistake
My knowledge after 2 years by using this software is not at level expert

Hi Kjeil,

the only chance to see what is going wrong is if you attach your project. Just with the screenshots it´s just guessing.

Hi Kjell,

as Oliver explained:
Solenoid devices like signals or turnouts are used for the securing/locking of the routes.

Thus only routes can lock against each other which contain at minimum one identical solenoid device.

Take a look at the routes switch in your first post (picture error...). I took a look at these routes in the tour editor and had a look at the part of the route where the trains would crash.

I attached two pictures:
I framed the meeting point of the trains with a magenta colored box.

Do you see it?
These two routes don´t have a solenoid contained in both of them. One route contains only the left and one only the right signal.

The route wizard always records also the signal in opposite direction (I tried it with your project). And it is absolutly to overrule these automatism by editing the routes afterwards. As far as I see this error is most (maybe in all) of your routes. I think you edited the routes after their creation. You need to correct all these routes.

Hi again,

by the way: next time export the project with the WDP Startcenter. There is an option to reduce the backup amount (e.g. no vehicle pictues) so it will be suitable for the forum.

Hello

You wrote I attached two pictures
Sorry, I don't see or find any new or updated picture
By the way, just discovered the possibility to block for transit in your software, this one was very useful

Hello

Ok, no it is clear for me what cause collision.
The light at end of the route was disabled after route was created by using editing tool. That is done for all routes and will be corrected.
Thanks a lot for your kindly support.
