Setting up switches

I have a section of track through an abandoned industry. I would like to install the switches at both ends so they default to the main line. As it is, one directs the train down the main line but the other defaults to sending the train down the abandoned siding. Can I change this and if so, how?

Secondly, I have a track that ends in a simple loop. Can I set that switch to automatically change every time a consist passes through it? It matters not which way I enter or exit the loop and I want to automate that switch for convenience sake.

Lo

P.S. I did it again. Disregard question 1. I figured that one out.

You could set up a trigger system for the switch itself. IN survayor using the session layer select the track icon. then click the third bubble in the window which should bring up the different types of track markers. Place the trigger at the point in which you want it to reset but far enough as to not interfere with your consist on the turnout itself.

2. NAME THE TRIGGER, click the question mark in the trigger section then click the trigger and name it....

3...ON the menu bar on the top of the screen to the right is 3 little bubbles, click the one with a square in it.. this is session rules... in this munu click ADD...... Then select TRIGGER JUNCTION a fun list of rules applys...

Hope this helps and have fun...
 
The train will always take shortest route it see's. In the case of a loop it means backwards. To avoid this use a direction marker to keep trains going the same way around the loop. Place a TM near the end of the loop and set the junction to enter the loop the wrong way. This is because the train will change the lever to enter the loop and when it is clear the lever will default back to the wrong way. When the train get's to the TM the only clear route it can see is the correct way out of the loop.

Click to expand...

For 3 above where is the the little square, any chance of a screen shot.
 
More questions.

I do not see anything in Session Rules named "Trigger Junction". Under a different name perhaps?

When placing track marks and triggers, which goes closest to the junction and do they have to be between the junction and the first spline point along the track?

Do I have to place one or both on both tracks exiting the loop?

@LoGrant54 - You need to add two rules to the session:

Place a Trackmark or trigger anywhere on the loop track. It is most realistic when placed about 3/4 way around the loop.

First add "Check Trackside" rule, click "Edit" and specify the trigger or trackmark name that you placed. Select the "Enter" radio button and also check the "Auto reset this rule" checkbox.

Then add the "Switch Junctions" rule. Indent it one position by using the right arrow button at the bottom of the window. This will bring it under control of the check Trackside rule.

With the Switch Junctions rule highlighted, click the Edit button and "Add junction". Select the junction to be controlled. To set the desired direction click the button next to the red X.

The junction should then change position when a train reaches the trigger, and return to normal when the train leaves the junction.

If you choose to use a trackmark then a trigger is not necessary. Spline points have no influence. The train should always enter the loop in the same direction.

Hope that covers it.

This is getting infuriating. I spent all day yesterday trying to get this switch setup the way I want it.

I can get either a track marker or a trigger to trip the switch once and only once and then only from one direction.

Do I need more than one TM/Trigger to get it to switch from both directions? Wouldn't they interfere with each other or just be redundant?

Also, in the Switch Junctions window, would someone please explain that thing next to the red X. I gather it sets junction directions through the switch but have no clue as to how to set it up for simple two way switch. Which way do I set it? It matters not which way the train enters the loop. I don't need the switch to change when entering the loop. I need it to switch while passing through the loop so it will be set correctly when I exit, regardless of which track I'm on.

All you need is to place the loop large enough to take all of the train and clear the junctions radius. Place a direction marker so all trains enter in the same direction around the loop. Place a named TM at least 3/4 of the way around the loop (set a small radius) or to a point that allows the train to reach it and clear the junction at its rear. Set the junction towards the exit path, this will then be the default setting (again reduce the radius of the lever). Your train should now drive to the TM by changing the junction lever and enter the loop. Once in the loop it will head for the TM and as the rear clears the junction the lever should revert to default (set towards the exit path). When train reaches the TM its next command should see the exit path already set and continue out of the loop.
 
@LoGrant54 - Are you driving the train manually or using AI?

I set this up in Trainz and noticed that the switch doesn't return to its original position when the train exits the loop.
To counter this, I added another rule: Switch Normal. Edit it and add the junction controlling the loop.

Set the first line to read: "Not All Junctions Controlled".
Set the second line to read" The following junctions will be reset by this rule".

The junction then returns to normal on leaving the loop.

I later added a signal on the track leading to the loop and another past the trackmark and near to the junction on the exit side of the loop. I found that AI trains will stop at the entry signal, pause and switch the junction to the entry position, even without the extra rule being in force.

The icon/button next to the red X depicts a junction. If the junction being controlled is only two-way then ignore the centre position. It would have been easier to understand if the icon had been drawn the other way up. Mentally rotate the image 180 degrees and then it would look like a Y, with the left arm indicating the left position of the junction.

Thanks guys.

I'm still building my first route and haven't even delved into AI yet.

I knew it was something like that but couldn't see how it worked. I came to the same conclusion you did. It would make more sense if it were flipped vertically.
