Re: Chaining transits with a different locomotive #dispatcher

 

So, you are not continuing this train with a new transit, you are in a "tag-team" with another train.
That is, somewhere in the middle or end of Transit A you want to run a different train on Transit B.
If you built transits with a 1:1 correspondence with trainonfo files, you can specify the locomotive in traininfo.
When you "load traininfo B" action in transit A and that traininfo file B specifies locomotive B, then Transit B will run loco B.

Re: Automatic Dispatching

 

If you upload the layout data xml file to the group's ProblemsBeingWorkedOn file folder we can review what you have done so far. ?Which turnout has the issue with the continuing route?

Subject: [jmriusers] Automatic Dispatching
Date: Monday, March 24, 2025 9:25 PM

I've tried several different ways to get trains to run automatically, but I keep running into ( maybe I should say "creating my own") roadblocks.? At 83, I'm not sure how many more wrong ways to do it I can afford to try.
?
I've set signal heads all around the layout.? I try to set Blocks, Sections and a Transit to run a train and I get it set to go through several Sections, but then I get to a turnout and it will allow me to set the diverging route out, but the continuing route isn't available.? I can't find what's different between the Block on he diverging leg and the one on the continuing leg of the turnout.
?
So, I read some of the JMRI documentation and decided to try using Signal Masts and letting JMRI set up Sections and Transits on the fly.? I took a portion of the Panel and deleted the signal heads around a turnout to use the Set Signal Masts menu.? It sets the Masts for both routes entering the frog end of the turnout, but there's no option to set a Mast with signals for the points end of the same turnout.
?
Before I waste any more time on rabbit holes, can someone steer me to the easiest way to set up my goals?? Or point me at the page in the JMRI documents where I can read the proper steps to take and the order to build it?
I'd like to:
1.? Be able to send a train autonomously from the modeled layout into a specific staging track.
2.? Be able to have trains scheduled to come out of staging into the modeled area at preprogrammed clock times or upon specified events.
3.? Be able to manually trigger a train in staging? by selecting either the train or the track it's on and select where it needs to go.

Re: Java version 21.0.6 #java

 

Thank you Peter.?? I see you are running that combination.? I will probably change to JMRI 5.11.4+, as I could be affected by the NCE consist backup/restore issue.

Keep using Java 21 unless you run into issues. If you do have issues, please report them.

I have just upgraded the club computer to Linux Mint 22.? As part of that upgrade, the system installed Java version 21.0.6.?? The JMRI version installed is5.2.?? I plan to upgrade it to 5.10.? Will that version of JMRI be compatible with java 21, or do I need to change to java 17??? I don't see that java 21 is recommended on the JMRI website.

Did you do the following
Create train length blocks / make each block into a section / create a layout panel without any switches / create the blocks physically by isolating the ends of each block and add detection to each block / physically on the actual layout ?include the switches you have at the end of a block / create sml virtual signals at the ends of every block on the layout panel-no real signals are needed / create transits /run trains.

That will enable you to run trains automatically from one point to an end point or continuously in loops including trains chasing each other.

If you want to use switching then create a second layout panel. ?Without changing your wiring physically now create a second layout panel with every switch in its own block.
Create ghost blocks for the switches-need latest test version of jmri software.
Or use logix to tell the virtual blocks you put switches in when to occupy them.

Re: Script help please #scripting

 

Richard,

One way to share data between Jython classes is to use sensors for states and memory variables for values.

If you really want to share the data within the Jython context, you have to use the "global" option. ?When a variable is modified within a class, the local variable will be modified. ?This will not be visible to other classes. ?If the first statement in the function is "global varname", the subsequent changes to the variable will be visible to other classes.

Here is an example:

# declaring and initializing a global variable
global_var = "I am a global variable."

def func():
??? # accessing and modifying the global variable within the function
??? global global_var
??? global_var = "I have been modified."

# calling the function to modify the global variable
func()

# printing the modified value of the global variable
print(global_var)??? # Output: "I have been modified."

I can set a variable with the loconet result in its class , but the value won’t show up in the other classes

I have tried using a variable set at the start of the script

This will show up in the different classes, but i can’t change it in one class and it stay changed in the next class

Lou, what decoder type are you using for those 150 Roster Entries? Often decoder definitions include the function key defaults.
?
Are you comfortable editing the XML directly? If you are, you can set up one and then copy the updated block in the XML to your other 149. Then Rebuild the Roster Index.

Re: java

 

Short answer: no. Longer answer: don't bother with Oracle's Java. There are
other options, none of which will ask for a subscription. Oracle Java (other
than version 8) is only available as a JDK and is meant for developers who are
writing Java code. Oracle wants to keep track (?) of people writing Java
programs.

Do go to JMRI.org/java and read that page carefully. There are *free*
downloads for Java runtime (JRE) for Java 11 or Java 17 from a few other
places besides Oracle.

Louis,

?

Many users have switched to Azul JAVA which does not require a subscription.? Azul also offers a JRE (JAVA Runtime Environment) installation which is much smaller than the JDK (JAVA Development Kit) installation.

?

I’m using Azul JAVA 17 on several Windows 10 and 11 computers with no issues.? I used the ‘.msi’ installer.

?

Make sure you remove your old JAVA installation before installing a new version.
