misdirecting switch enigma

[bl4882]

Hello all,

I just laid a switch and the arrows indicating the flow of traffic are reversed. When the green arrow points to the left, traffic goes right. When the arrow points right, the traffic goes left.

Here is a picture for clarity. BTW, ignore the red dot. I inadvertently added it when processing the screenshot and did not notice it until now.

This switch is laid on a 1/2 degree (30 minute) curve, with approximately 20 meters of straight track just before the points. I relaid it twice, using different techniques, and the problem remains. Weird; never seen it before.

Well, mystery fans, can anyone think of why this might be? Any help will be greatly appreciated.

I get that all the time. The track is trying to go to the right, but the next spline point is pulling it left, so there's a slight wiggle in the joint.
You need to move the spline point out to the side or backward toward the junction until the spline snaps over to the other side.
One solution might be to add a spline point to the diverging line and put it as close as possible to the junction. Then adjust it until the train goes in the intended direction.

Too many spline points - try this

Thank you gentlement for your prescriptions. I tried them both without success. Strange. I've laid switches like this before without a hint of this trouble.

What I will do, I think, is just name it "Twilight Zone Switch" to remind me how to set it, and move on for now. I have about 60 miles of main line to go to reach Paso Robles.

Thanks again, though.:wave:

I occasionally have this problem, and the only way I've been able to resolve it is to move the turnout farther down the track until it works correctly.


Good luck, Joe

Hi Bernie,
You are correct, you have hit a spot on the board were normal laws are twisted! I find this usually happens near the boundary of 2 boards.
As some one else said moving the points away from the 'cursed' spot works.

However if you can't shift the points try this:
Set up all the signals you require, but on the two diverging tracks put the main line signal on the branch line and the the branch line signal on the main line .
Now use the split spline tool on the first spline point on the two diverging lines and swap them over.
The points and signals should operate correctly now BUT! if you ever replace or add another signal to that junction TRS realizes you have fooled it and sets the junction in reverse again!

Hope this helps,
Lindsay

Hello Jrfolco and Twodorgs,

Thank you for your suggestions. I think a rebuild a discreet distance from where the original turnout was planted might be the answer. Not now though; making a chicken stew for dinner.

Anyhow, Twodorgs, your diagnosis is on a very high mystical level. If it doesn't work maybe I should contact the Archbishop and arrange for an exorcism? :hehe:

Seriously, thank you for your suggestions and I will surely implement them first thing tomorrow.

This will always happen when you place a junction on a curve and will depend on the track used. If the track is made as 2m lengths it will normaly fit ok but longer lengths dont bend aswell so tend to overlap the main track. By lengths i mean how the creator of the track made the track for the spline. Use straighten tool to a piece of track ahead of the diverge will normaly solve it but not always on longer length track. The first spline point after the diverge needs to be moved further left as it is making that line go across the main track and come in from the right side. If you zoom in very close to the junction you will see the track overlap even by the smallest amount.

Stagecoach,

It worked! It required only a tiny reconfiguration along the lines you suggested to solve the problem. I have, if you will excuse my effrontery, renamed the switch "Stagecoach turnout" in your honor.

Thanks muchly,

and thanks to all others who offered help,

Bernie
