AI TRAINS IN SCENARIOS

[7817]

I am trying to create a scenario (Weardale and Teesdale) and have created a number of AI trains.

One of the AI trains refuses to move at its programmed time to start. It is not held up by a signal at danger, it is out in open country but, when the time I have set for its starting arrives, nothing happens.

This affects the running of the player train as it (the AI train) is on a single track section and the player train is held up until the AI train clears the section - which, of course, it never does.

I have had this happen on odd occasions in other scenarios I have created but in the past I have given up and removed the AI train.

Has this happened to any else when creating scenarios and is there some sort of 'pecking order' for AI trains to run - other then the usual priorities such as express passenger takes precedence over stopping passenger, and ditto over freight etc.

What is the train type of that AI train? Special, Passenger, etc?

[7817]

Both the player train and the AI train are standard freights.

But I had the same problem when the AI train was lower down the order (i.e. low speed freight).

I understand the principle of priorities with different types of train but that doesn't explain why an AI train of equal or lower priority wouldn't, at least, move at its allotted time - even if only to the next signal.

[Tim van der Leeuw]

Is there another train somewhere on the line that has a higher priority? Does it help to raise the prio of that one AI train?

(I have also had dispatcher trouble with scenarios, with trains that I know should be able to pass one another over crossings with the timings and order I try to specify, yet the dispatcher refuses... Single line working and the TS Dispatcher are no good friends)

The section of line I am working on has a double track section, leading to a single track section of about a mile, then double track again.

I want the player train to be cleared to proceed over the first double track section to the start of the single track section and then be held there until the AI train passes.

If I raise the priority of the AI train above that of the player train, the dispatcher gives it (the AI train) priority right through and I can't move the player train up to the start of the single track section until the AI train has passed right through.

As you say, single line working and the dispatcher are not good friends. I'm guessing I'm going to have to try something else.

I have had similar problems in creating scenario's. The only solution I have found is to delete the train causing the problems and place it in a different position or leave it out entirely.

Ive seen this alot, on different routes so it's a game bug rather than a route one. The only way to fix it is to delete that consist and place a new one, usualy in a slightly different position helps to be sure.
