implement passing absolute stop signal on restricted aspect ( blinking red ) ?

[2-8-4]

don't know if and how this was implemented on CTC panels with the present levers and buttons

[ecgconnelly]

This is in progress - can't believe I didn't have an issue for it set up 🤦‍♀️

Haha the icons are literally from JMRI, through the magic of free software and the GPL license. The icons are in both this repo and JMRI.

Really, TSCAD was java? That explains a lot. And yeah, you could absolutely build a hardware panel - but you know Run8 would change their track layout the next week.

No need to rush, Emilia.

Let the bug reports and feature requests come in so you can prioritize and sort them out later.

I’ll go looking for some icons on that JMRI site. Are your panel icons in your GitHub?

You program USS8 in C language , while JMRI and that failed commercial external dispatcher were programmed in Java.

In theory it would be possible to build a hardware CTC panel even and interface this to Run8 instead of a model railroad. How cool is that?

Keep up your good work, I like it very much.

Hi, Emilia.

You implemented passing an absolute stop signal on restricted aspect by pressing CTRL if I understand correctly?

You ported a model railroad implementation of CTC, and for model railroad control it is hardly necessary to pass an absolute red stop indication. So the JMRI programmers probably didn’t implement this.

Obviously, simulations like Run8 can strictly adhere to prototype practices, and on the real Bakersfield Sub CTC panel where special smaller levers above the normal switch and signal levers. I think specially for the purpose of ‘unlocking’ a control point’s switches and signals for manual switching. Implementing this would require some graphic design, working out the signalling logic, thinking how to implement this in a reasonable fashion for your project.

Perhaps for the future?

But how to differentiate between the absolute stop and restricted after the CTRL press? Will the signal light blink red? What about the direction? What about the switch being manually thrown? The unlocked switch lamps blink, stay dark?

Best read up on prototype practice or find an ATSF USS CTC machine manual at SFHS or somewhere else?

Hey Edwin -

Correct. This is meant to represent a pull or twist of the code button, as described in this railroad.net post. I am aware that some machines had separate buttons the operator would use to request a call-on but I don't see much of a benefit in adding that.

Not really. USS8 currently uses JMRI graphics, though we do have an individual currently working on much nicer replacements. JMRI logic is not used and honestly probably wouldn't be that helpful.

special smaller levers above the normal switch and signal levers

This is exactly the plan for unlocking switches. For now, that will probably take the form of copying the fleet switch images to a position near the switch lever. We'll see how froggy our graphics contributor wants to get.

But how to differentiate between the absolute stop and restricted after the CTRL press?

I could be wrong, and prototypes may differ, but to my knowledge, the current lamp behavior after requesting a call-on signal is correct for at least some prototypes. Restricting is not Stop, therefore the machine displays a Proceed indication on the panel.

What about the switch being manually thrown? The unlocked switch lamps blink, stay dark?

Probably go dark. I seem to recall reading something to this effect but this is easily changed if information to the contrary surfaces.

Best read up on prototype practice or find an ATSF USS CTC machine manual at SFHS or somewhere else?

I'd love to see such a manual. I've looked and although there is more information now than I was able to find circa 2015 (see the veritable trove here) I have been unable to find an actual manual. Plenty of catalogs, articles, and individual machine drawings but not much beyond that. In any case the research aspect isn't all that fun for me...

hi, Emilia

Are you still working on this project? There have been no updates, and on teh Github there are no packages anymore either?

It still works with Bakersfield Sub i presume?
