Re: How to make multiple trains chase each other
#automation
#dispatcher
Scott,
Based on an example from I thought Dave Sand: transit_chaining.py , with thanks for that,? I wrote a modified script in Python.?
This resulted in two python scripts, controlling my trains.? First script is Transits_SPV23.py, always running.? In this script you create a separate transit list for each train. This contains the transit list, the train info file and the waiting time between the transits in seconds. From this file the trains are started by means of a sensor. (Start-train). Then a separate Python script is started for each train. This script ensures that the trains run automatically under Dispatcher.?If desired you can modify the scripts. For example by replacing the start sensors with a time table.
Enclosed a screen image of layout panel in which train 515_m1 is running.
And also three python scripts as an example. Hope that this will help you.
?
Best regards? Willem
Almere, the Netherlands.?

Re: How to make multiple trains chase each other

Assuming there are no issues with contiguous blocks, sections verified, and real/virtual signals (if used) working, then:
Each train should have its own transit, even if each follows the same route.
Two trains cannot use the same transit at the same time.
?
As a rule, I always use a traininfo file and transit pair to define a unique train run.
That keeps things from becoming confused.
?
Mostly I use each run as "to safe sections", especially when I have passing movements.
For reversing movements on the main, I sparingly use "as far as".
?
I can't stress enough that you treat each train movement as choreography.
Walk each movement through logically and in concert with every other train's interaction.
Automation is more of a dance routine than just pressing the "go" button and watch what happens.

Re: Making a plant switcher work correctly
#operationspro
I think I got it!! We are moving cars from interchange drawers to ADM Pass. Then ADM pass to the spurs, yard tracks and C/I tracks. Then to Yard Lead and back to Interchange Drawers.. Seems to be working.
Pete, a most hearty THANK YOU for all your help. I am very grateful. |

Hey John,

Yes, I understood that to be the case, so if you look at image 3, this is the filter on the track at "Interchange" (remember, I used only one track to have the local do it's work before and after ADM).? The filter reflects the loads and the one MTY that are allowed INTO the interchange track.? Because, for this example, I tasked the Grain Hopps to do double duty (i.e. it can load with Corn in the Interchange and with DDG at ADM), they need to be allowed in in either load state (loaded with DDG or as an MTY).? Also, look at the image (image 4) of the schedule for the Interchange called "Load Exchanger".? You will note that the "Grain Hopp" lines receive both DDG and convert to MTY, as well as receive an MTY and convert it to Corn.? The line that applies depends on which way the car shows up when it is delivered here.
?
Part of the reason this may not seem right, is that I did not create a separate type of hopper for the DDG and the Corn.? This was due to the small forum discussion over whether the same car could indeed deliver corn and then reload with DDG occasionally.? Again, for my example, I supposed they could be used for both and did not create a third car type for this exercise.? If you want to have "4bay Cov Hopp" cars be the DDG vehicle, then create a new car type and substitute it into the appropriate places in my example.? Bear in mind that doing so will exclude the occasional respot at ADM from Pits 2 & 3, over to the DDG track.
?
As another perspective, take a look at the attached train manifests for the two trains I used.
?
This exercise was about trying to answer your original question of whether JMRI could work one industry.? Short is yes, and I built this example to show you how.? We can tweak the operation however you desire, just keep the details coming...
?
Happy to help, hope it helps,

Re: BDL 716 etc
#digitrax
Thanks for getting back to me.
Somebody volunteered to help with some testing. Unfortunately, none of the four methods JMRI knows for setting op switches seemed to work for the BDL716. So we’re somewhat stuck at this point. The next step is to try to do some reverse engineering of what the BDL716 understands, but that’s a slow and complicated process, and I don’t have direct access to a BDL716.

Re: Making a plant switcher work correctly

Hi Pete and thank you, thank you. You spent a lot of time on this...but...theres always a but.
?
When Cov Hoppers are taken to the Interchange they will be empty. When they turn around thats when the have corn in them.?
The 4bay Cov Hoppers are the only ones that carry DDG. So they would be loaded when taken to the interchange and empty when they head back to the ADM plant for refilling.?
Same with the ethanol tank cars. Loaded with ethanol when arriving at the interchange. Empty coming back to be reloaded.
?
Thats all so far. I wanted to do this a step at a time to keep my thoughts straight.
Again a big thank you for your work. |

开云体育Steve, ?? ?Yes. That’s the next step. It got pretty late last night by the time I posted, so of course, woke up in the middle of the night going why not post this to the NCE group! ? ? ?Your note is a good reminder.? Thanks Glenn?
