Signal waiting for train to approach?

D

Davie_UCF

Here since 2001, Trainz!!
How do I stop this from happening, i'm guessing my signalling must be flawed.

Its a single line with loops at the stations. I have branch signals protecting the entries to the loops and a distant ahead of them further down the branch.

Yet I still have to get close to the signals before they let me into the station or loop.

what am I missing here? Its making my AI timetables confusing as I could be saving a lot of time by trains not having to go half speed then stop at these signals..

Thanks :)

Which way do you have your points set? Do they favour one line as the main line and one as the loop? I have a double line junction on my Sunderland route set up exactly as it was in real life and the train coming from the branch to the main is ALWAYS held at the signal even if nothing is coming, while the AI checks that nothing else is approaching.I actually think it makes it more realistic.
 
David,

There is rule to set up paths, and an associated driver command to select them, which should work for you (if setting the points does not). Can be a pain to set the rule up - especially since the setting up dialog is in French! - but easy enogh when you get used to it.

I can't remember the KUIDs / Names just now but if you are interested then I will look them up for you.
 
I'm actually using the path rule, which makes the single line work. The signal at the platform is red.. i'm guessing if the next signal is red the signal at the entry of the station loop will wait for the train to approach?

David,

I guess you are using the "Select Path" followed by "Autodrive (to trackmark)" commands for the driver?

Presumably you have "Starter" (Home) signals at the platform end(s) in the direction of travel - as per prototype?

Hi David

I kept running in to this problem when I started programming the SnC with SCS2006. After a lot of experimenting I discovered that it was happening because I wasn't setting the path for the next section soon enough which meant that the signal controlling it wasn't clearing early enough. This sounds very similar to your problem. I then started setting the path 2 blocks ahead which solved the problem.

Well i'm leaving the stations passing loop exit open for ongoing trains so the train in platform only takes the path when its about to leave, mainly so I can put in other AI trains later, or drive my own train and not get stuck waiting for AI for miles..

So it is because there is only 1 signal after the one that is "waiting for train to approach" which is red due to the stations loop not being open until the train is ready to leave?

Hi David

If possible try setting the path for 2 stations ahead on one section and see if that cures the problem. I can see that it may not be the ideal solution for single track working but it should confirm if it is this that is causing the problem.

I also had this issue at Settle Junction on the SnC with trains leaving the main line and I cured it by adding an extra pair of signals (home and distant) further down the line. Something else you may wish to try.

sounds like you are using a signal with a config setting 'home' value as 1. these always wait for a train to approach and you have to get right near them for them to clear. it also causes the overlap to become the distance to the next signal, where normally it is very shortly beyond the signal. the name "home" might be somewhat misleading and it is made for specific instances where this behavior is required. try using a signal that is not 'home' the distant signal will still work with them.
 
Hi again David

Have you recently looked at the signalling tutorial on

http://www.trainzclassics.co.uk/

There is a section specifically about block signalling passing loops on single line track using TC3 signals. It must be 2 years since I last checked it and I found it interesting to read over it again.

In the UK our signalling has "approach control". This means that when a train is proceeding to a lower speed route it is brought to a stand or nearly at a stand at the protecting signal before it clears. It works by means of a timer so that the berth track circuit ( track circuit immediately before the the signal) has to be occupied for a specific amount of time before the signal will change to a proceed aspect. So in one respect when an AI train stops at a junction signal when there is no other train involved is a reflection of real life signalling.
 
There used to be a signaling pdf guide back in T2006. Is this document still around?
Has it been updated?

Sorry Davie, didn't mean to hijack your thread but you reminded me I needed this again.
