Following an AI train

[CajunRon]

Hi All,

I've been away from Railworks/Train Simulator for a while and trying to get back interested. I remember an earlier version having a scenario named "Riding the Yellows". I think it was on the Northeast Corridor route In this scenario the player was challenged with meeting a time table while following an AI train that was one or two blocks ahead of it. I've tried modelling this scenario on Train Simulator 2014 on the Northeast Corridor but I get an error message that my route is blocked by the AI train in front of the player train no matter how many blocks in front that I place the AI. Both the same consist and are programmed to go to the same destination. What is the method for putting an AI train in front of the player train so that the player has to contend with yellow and red signals throughout the scenario like the legacy scenario of yesteryear?

Thanks.

I'm pretty sure that the scenario you remember is called "Chasing Yellows". You should try opening it in the editor to see how the scenario writer accomplished the chase. If fact, clone it and try monkeying with one instruction at a time until it fails to run. I cannot recall which route included that scenario, but I think it may have been Oxford to ???, which, of course, is now called something else.

Thanks OldProf, I'll look around for that scenario and try to "reverse engineer" it. (They do say that eye sight is the second thing to go with age...and I don't remember the first ). It was many years ago...in fact I'm now wondering if it wasn't a MSTS scenario so maybe I need to alter my question....

Can an AI train be positioned several signal blocks ahead of another on the same route in Train Simulator 2014 without the "path blocked" error message... (which would be some what amazing that such a basic scenario can't be written in Train Simulator).

<ScenarioDesc>I’s a busy weekday evening and you&apos;re in charge of the 1806 to Frome. To compound issues however, word has been received that the train running ahead of you is having problems. Do your best to keep to time. 35mins/Easy.</ScenarioDesc>

I just finished a Workshop series on Steven's Pass called "Boeing Express". After part 2 you are basically "Chasing Yellows". The way he did it was at the start of the scenario you and an AI train were in a siding, the AI train would get a green signal before you and then you follow after it. You had to keep on your toes because the signals were always yellow or red! That would be one way to do it.

that's all about priorities.
there is no other way in the game to tell game engine run one train ahead of other, regardless of is it AI or player's train

so if you want to run other train ahead, give him highest priority: Express Passenger, or Express Freight. use "regular" or "low" priority for trains which you want to stop at signal and wait for track clearance.
high priority train always blocks low priority train, if their paths are crossed

Good luck!
