SafeTran Signals with rules for UP and BNSF?

[Dakota]

I spent way too much time being obsessed with learning the internals of signal scripting, trying to figure out which of the signals out there really do implement the rules used by UP and BNSF. There are the original SMMDIgital ones (NS rules), the SMMDIgital and SMMDigital_2 (which seem invisible) ones that are now part of RCAP, Pacific Surfliner (unknown logic, the LUA is compiled), and the Kuju RailSimulatorUS. What's interesting is that some(!) of the SMMDIgital signals have been enhanced by Pikehikr to implement Absolute Permissive Block Signaling. Trying to sort out the bewildering differences in NS vs C&O vs CSX vs NORAC ?? I finally hit the wall after doing a bunch of work to enhance the DEBUG output and learn how it all works.

I give up on APBS... I don't need it for the route I am doing. But I do need signals that implement advanced aspects as well as restricted (flashing red) "exit" aspects and links that pay no attention to blocking inside the yard. . To make it realistic they need to be SafeTran single-hood 3 light, not USS or Griswold. Can someone tell me definitively if there are SafeTran signals out there that implement the UP/BNSF hybrid speed/routing signaling rules?

Here are the signals in use on the route I am extending. Do any of these qualify?

PS Maybe not SafeTran. This is what I'm looking for for mainline.

RCAP SafeTran for CSX turned out to be a good starting point. I now have a completely separate "RCAP: ST_UP_xxxx" signal set under RCAP. I have worked on the signal scripts to make the debug output far more readable (codes translated back to manifest constants, extra info, much more). I'm working from the parts with a little JavaScript to assemble the final LUA from the common and specific scripts. Then a post processor for the log files to remove the annoying noise. Separate blueprints of course but sharing the textures and GeoPcDx like the CSX, NS, and NORAC. I have the Pike's Tutorial route/signals set up and in the process of testing. It took a load of time to find the stupid errors I made. LUA can behave so crazy with certain syntax errors. How can DefaultInitialize() be called only once yet Call ("BeginUpdate") was being called twice??? All in one function?!?!?!? Missing 'end' and no run time error on that. Woah. Well I found a cool LUA 'lint' tool that saved my a**. Onward. I will have at least a UP signal set eventually, with speed sensing and functioning Advance Approach etc. Lunar is flashing red. Now I just need to get the subtleties of UP signalling and implement it correctly. There are signals with the single red below the three head, and bidirectional main heads, just like the photo in my previous post. WooHah!

The signals in your picture are either SafeTran on Lincoln Industires signal masts, or completely Lincoln Industries.

The RCAP pack has the SafeTrans that have been in use on NS since 2008. It does not have the narrower hooded ones (like above) that are more recent. They may look a little more prototypical on some BNSF routes, but I've not seen them used on CSX or UP. But then again, I'm only grounded to a single part of the country.

Just FYI, there are two major players in signalling these days - Siemens and Caterpillar. Lincoln Ind. is a subsidiary of Progress Rail, which is a subsidiary of Caterpillar. Union Switch & Signal and Griswold Signal were folded in SafeTran, which was folded in Invensys, which sold it's signal business to Seimens.

Interesting and thank you for that!! I am completely unable to do 3D modeling (no hope for me) so I am limited to what I can do with signal scripting and the existing models & textures.

[ForceGhost]

Heh heh. I've done a little 3D modeling, but for me, scripting is like reading Chinese in the dark while trying to escape from a Houdini water tank.

Try this pdf within the dev docs: 3.01 Signal Setup & Scripting

I'm in exactly the same position, and there don't seem to be many informative tutorials available. Is there anyone here who has actually built and scripted signals?

[Dakota]

Thanks I have all of those original RW Dev docs, and the signal scripting one is full of good info all right. See my other thread.
