AI trains passing stop signal

[Approach_Medium]

Hi;
In a very simple test route, I have found that AI trains will go well past a permissive stop signal, and come very close to, if not actually running into a parked train before they finally come to a stop.
If I change the signal to an absolute, the AI trail will stop short of the signal.

Supposedly, for a permissive signal, the train is supposed to come to a full stop behind the signal, then proceed at restricted speed.

Any idea of why this happens?

Thanks

What version of the Mighty Trainz are you using?

Oh, sorry. I forgot to say. It's TS2009 SP2 beta build 39756

I guess I should do some more testing, and report it in the TrainzDev forum if.

More details on this is in my post in TrainzDev forum in the Public Test forum.

Indeed,

ALL trains are meant to stop on the 'correct' side of all signals displaying the STOP (red) aspect. If the signal is then designated as a 'Permissive' type, it may be passed depending on certain circumstances (which vary from rail system to rail system) but usually involve the waiting for a specified length of time, the known presence or otherwise of a previous train or if the signal is known to be defective (displaying stop when it really should be showing proceed) and other such variables. If the signal is of the 'Absolute' type, unless there are exceptions to allow for the passing of the signal under specific circumstances (such as if the signal has 'failed safe', associated points are defective, etc.), then the signal MUST NOT be passed until it displays a clear or proceed aspect. Once again, it looks like the good people at Auran have developed yet another version of Trainz without consulting the peole who really know how these things work. By all means let the Traindev site know of this 'defect' but if past process is anything to go by, they'll NEVER get it right...

Good morning;
I received a reply from my post on this issue over in TrainzDev/Signalling forum.
The reply was that this is how Trainz is supposed to operate, and apparently this is prototypical on some roads (but maybe not any here in the US).

I can quote rule 291 of NORAC, which basically says that a train must stop, then proceed at limited speed on a permissive stop.
I guess that, unless I want to modify the signal.gs file myself (and I don't think Trainz will let me do that), I have to use only absolute signals on my US routes.
