Do Different Locos Interact Differently With The Signalling?

[Vern]

Came across a bit of an oddity running my Mount Hood route in TS12. Running a train using one of the Chinese locos I was able to leave the AI to drive from one end to the other, including handling the run-rounds at the Switchback. Bringing out a consist of the S&C Class 40 plus Mark Ones, I could not get the AI to run round the train, nor was it able to clear the block signal for the long 11 mile section (message about being unable to see next signal). This is probably a throwback to the long standing problem of Trainz not coping with long sections between signals but, 1. I thought this had been addressed in TS2010 onwards and, 2. Why could one loco type work the signalling correctly but not another.

I have used the UP signals from the built in Mojave Division so not sure if these use different scripting from the built in NA searchlight signals, but still an oddity.

Does one of the locos have a cab signal aspect display?

The Class 40 certainly doesn't being good old 1960's British tech, but maybe the Chinese one does. Would that make a difference?

Moral of the story seems to be, stick to routes where the signals are less than 5 miles apart even in the later versions.

That would be my take on it, as to if a cab aspect repeater makes a difference or not, I dunno, just tossing out things to check. Main reason I don't do prototype routes, remember the infamous MSTS Marias Pass Cutbank Coupler Curse? Switches more than 5 miles apart caused that problem, my solution was to add a siding about halfway, and the Prototype Puritans didn't like that idea since there's no switches there in real life. Add more signals, screw the purity of the prototype.

Just passing!
To keep things "Accurate" for the purists (and myself) I use invisible track, invisible junction levers, invisible signals and invisible speed signals.
For example. I wanted Trainz AI to run round a train in a bay platform (dead-end) in a station. This would only work (because of the space available) if I deleted the buffers and extended invisible track under the platforms. The loco never gets that far, and it looks great. I suppose I need buffers that act as a permissive signal too.
I'll get to that, one day!

I have seen this loco\signal difference before. I believe it's related to scripts but have never been able to pin it down.

I have noticed that when the the S&C class 40 is emitted from a portal the lights are not set up correctly, with the red lights showing at the front. I've wondered whether the script is confused about which end is going forward, which in turn might be causing your problem. At 69 feet long the 40 also needs a lot of track to run round in, assuming the default junction trigger radius of 20m is being used.
