Switch re-setting

Searched the forum threads and the last time the subject was brought up was two years ago.
The last two wagons of a consist are being derailed by the switch resetting, I wonder if anyone has found a way around this bug?

Hi Gohst42,

This is not actually a bug, it's the way you have the switches, signals and track set up. There are ways around it such as the 'control junction' and the 'free junction' commands but these are usually not required if you set your switches so the AI only has to change one switch at a time.
All mainline switches should default to the main line, all ladder yard switches should default to the farthest away siding.
Only one signal is required on the main line at the entrance to a yard but exit signals are required at each track exit and on the yard exit to the main line.
If it is a passing loop exit signals are required at both ends and entry signals are required at both entrances.

If this does not explain things post a screenshot of the problem.

Hope this helps,
Cheers,

I regret to dispute the answer by Bill69. There are cars that derail, and cars that don't. Given the exact same conditions, a switch will change while the car is still over it derailing, and on other instances, another wagon passes without problem. Try to mitigate the effect by setting the point lever exactly over the spline circle. No guarantee, but bogie wagons are more prone to derailing than 2 axel ones. I would like to see the switch-back to default position eliminated. That will solve the issue.

My first attempt at posting a pic, hope it works.
The consist would be running left to right off single track to main line. I managed to stop it derailing as a temporary measure by moving the 05 signal to within the length of the consist (13 Bardon aggregate wagons)
Will check on those points you raised llebrez,

Hi Ghost42,

Yes Ilebrez does have a point, I do remember something about certain cars derailing.
However I think you could improve the situation by bringing the double track main line together before the junction to the branch line.
I think this would simplify the signalling and make the whole route run better.



Note junction 2 is set to default to the main line and junction 0 is set to favour trainz departing (northbound) the double track section.
The reason for setting junction 0 to favour northbound trainz is that trailing junctions are frequently slow to change and can cause an unwanted holdup on the main line, junction 2 being set to the main line may cause a bit of a holdup to trainz coming off the branch line but I consider this acceptable.

Adjusted track to Bill's suggestion, derailing cured but I now have a cornfield meet with traffic approaching from the left and consists departing the power station (the power station is fed with coal from both ends). Not very prototypical but I was thinking of linking the right_to_left main line to the power station feed instead of mainline to mainline.
Hope that is a little clearer than mud :)
Any thoughts?

get rid of the directional s first since your using track marks and I see your track mark is to close to the junction your coming off and that is allowing the junctions to reset to default since the train made it to its destination command....so moving the track mark down the line more will prevent that reset....
