...to the contrary...
Open TRS, as you would, to start the sim.
On the Menu, select Trainz Manuals. You will get a page that looks like the website. Scroll to see the Signaling Guide. Click, and a .pdf file will open, to the title page, TRSxxxx Signaling Guide.
This guide, gives not only the placement of signals, it also tells you how the AI Driver will interpret the signal indication...
First, you have to do your homework, studying actual employee timetables to orient you with signal rules.
Then, study the Trainz Signaling Guide, to memorize the signals to use, and how you place them.
A lot may be expected, to work right along with what you wish, and more.
However, this is a train simulator, and must be set up, according to actual practices of real railroads. That is a craft-trade, that has to be studied, and practiced, and yes, you will make mistakes.
The results may be silly at-times, however the job can get done, and no one will be hurt.
Many times, real railroads use methods, such as verbal track warrants, that help where signaling would be redundant, and sometimes not used a-toll.
Where you have created, or re-created a signaling-dispatcher nightmare, you may have to issue the command Stop Train, and drive through that block.
To help in this case, remember, the guide suggests, in so many ways and words, that you need to:
1)Place junctions correctly.
2)Place switch levers correctly.
3)Place the signals correctly.
4)Protect all junctions. That means adding the best signal, that can be placed at that point, to direct movement.
If you run long routes one or two signals between junctions can help long trains run more efficiently.
Since you have an unlimited budget, and signals add a colorful and dynamically interactive feature to you route, this added control, gives more of a sense of accomplishment.
Also Important:
When you place locomotive(s) on a route, select the properties radio button on your Train-cars Panel. Click on the item, and select a priority. This will be copied to other units in your consist.
You have a list of Drivers. It's not alphabetical, but the order should be observed, and custom Drivers, are added first. In the real world, that list is made according to seniority.
Remember that the arrows above the train-cars indicate direction priority. Real railroads move several trains in the same direction as "fleets."
Anytime you have conflicting movements monitor their actions, and dispatch accordingly.
Don't blame the Trainz Drivers, for mistakes in judgment that you made. If everything falls apart, just keep going and try to direct the movements in the best practical way. Every decision you make, and action you take, will train you further to your goal of making everything run smoothly and prototypically.
The ClinchTRS route, on the DLS, is one of the great routes to practice on, and it can be as complicated as you want to make it. It's also large enough to allow trains to pass, with time to watch several trains and make changes, before things get serious.
( I have seen them fully working) But I find they are an absolute pain to install. Despite my being a retired Locomotive Engineer!! But you need to understand the rules used to make the system work.
