You're a lifesaver. I've been driving myself crazy trying to solve this exact issue! I've gone back and reviewed all of your videos and am now a happy, happy subscriber. Keep'em coming!
Hi Jim, I've been watching a bunch of your videos recently and this one was just recommended to me. Just wanted to say thank you for sharing all of your knowledge! I don't have a layout set up but I'm hoping to start building something soon using these concepts that you're describing so clearly. Thank you!
I’m glad you liked this introduction. This was just a simple use of Logix to accomplish complex control situations! I have found a number of ways to use this JMRI capability. If you have a more difficult situation, let me know and I’ll use it to introduce the more advanced features!
Thank-you for the time you've spent creating these videos. I've learned a lot. One thing that you seem to have wrong is the signal locations for the lower track on this crossover pair. Signals 22A1&A2 need to be moved to where you have signal 21B, which should be deleted. Similarly, 21A1&A2 should be moved to where 22B is, and 22B deleted. Both crossovers would be part of the same interlocking, and all the signals would be at the entrances. This actually simplifies the logic by removing the problem you started addressing at around the 40-minute mark.
@mpeterII, thanks for your comments! I can see the logic you are using to arrive at that signal placement. I can even see that it might be a better solution by using fewer signals. However, it would take some Logix conditionals to accomplish a complete signaling solution. For example, if you put 22 A1 & A2 in place of 21B how would you handle the situation where turnout 21 is thrown (ie. set for the crossover)? You want to stop a train moving from left to right along the lower track before it reaches a turnout thrown against it. Thus, both of the signal heads, 22 A1 & 22 A2, should be red. You can't accomplish that with the signal logic in JMRI if you try controlling the two signal heads with either turnout 21 or 22. The JMRI logic would always have one head showing green: No matter which TO you use to control the signals, if either is thrown for the crossover, the top head would be red and the bottom green. Thus, you would have to create some Logix conditionals to make them both red if TO 21 is thrown, which is easy to do. The same thing would be true for the other half of the placements that you suggested. I think this just shows that, with a complex interlocking situation, there are a number of ways to skin the cat! The way I presented it in the video was the first one that came to my mind. However, I like your solution because it uses fewer signal heads. Either way, you have to make up some Logix conditionals to make the whole complex work correctly.
@@jimworcester981 You already showed how to do the logic with a crossover set against a route. While watching, I just figured that it would be a simple addition to use the same condition on both crossovers. I did notice that you'd already used up all the available spaces, but the new signal placement would allow you to combine blocks 1011, 102 and 1012 into one, thus saving two conditions. Similarly, blocks 2021 and 2022 should be combined.
You are correct! I think I am just biased to using more, rather than fewer, blocks to allow for more future flexibility. I use block detection to operate crossing signals/gates and that sometimes requires unique combinations of block occupancy. If you ever start playing with automation, more blocks are usually better so as to make things happen automatically and in the correct sequence. Again, many ways to skin the cat!
Hi Jim. Great videos, maybe the best explanations of JMRI details. Question, is it possible to make diverging route signals flashing yellow instead of green.
Yes! I think so! I would have to play with the set up in JMRI to answer for sure. I think you can do it on the page where you define a given signal head. Right now I don’t have the ability to test it. As soon as I can fool around with it, I’ll let you know. It also may require using Logix!
Hi! I made the same layout with virtual head signals (I don't have a signals hardware). When I try to do a Dispatch appears the following errors: "Found 6 error when checking/setting direction Sensors in signal logic for this Transit. Check Console log for details." In the Console log: "Warn - Section - West main 1 (IY:Auto:0003) , 2 turnouts missing signals ([ANT-EventQue-0]". Four rows errors One for each Section. Please help me! Thanks!
Lately I have been using the “We Honest” signals. They are acceptable, if not quite as detailed as other brands. However they sell for less than a third the price. Also, they are readily available while other brands are often on back order! I think they are all made in China! You can order directly from their website or through EBay. I’ve done both. For deciders, I’ve used Digitrax. Both the old SE8C and the newer SE74.
@@jimworcester981 Is there away we can have a Video meeting? I am just getting into the Logic part and would like you to see my first attempt is correct on signals masts. Maybe also how to set this up for dispatcher with all signals being RED and the dispatcher controls the signals. Never done this until now.

Thanks, Jim! That’s exactly what I need. The Logix was what was throwing me. Again, thanks!
Really cool! I was recommended this for some reason, but it was a really cool to see such an important tool in the rail trade. Thanks!

Excellent Video! Wich kit of lighting signals and decoder are you using?

I am glad you made the 2 Crossover videos. You helped me figure out my problem on my layout
BTW what camera are you using for making the videos?
Thanks! iPhone 11
