Reasons For AI Below Speed Limit?

[boleyd]

Often the train is slowed by AI to a speed below the "posted" speed. There is not always an observable reason for the reduction (usually 50%). Is there a method to determine why AI has slowed a train when the there is no apparent reason?

One is to check the state of the signal facing it. If that is all clear then one of the 'Doctorate of Trainz' holders need to be consulted.

Belive if signal is yellow the train goes at half speed.

AI may determine that a caution block is ahead, if there are not enough signals ahead, or a dead end track miles, and miles, ahead.

In many cases the problem can be solved it you find the spot where the caution/distant signal comes into view at driver eye level and then place an invisible signal at that spot. Trainz AI has never read any signalling manuals and it's not set up to work at reasonable human sighting distances as on the prototype so that means we have to get inventive.

Indeed: When AI sees a yellow or red, makes the consist to go a half speed. The issue is that if the signal is 10 miles away, the consist should not run at half speed. I may exaggerate the 10 miles, but really, it should be much shorter or depending of the line speed. It may be something very hard to do, as this issue has been around for far too long now, and many people have made noise about it.

Note: If you find the offending signal, you may set an invisible signal just in front. If the signal is yellow, the invisible one will be green, and the AI will see green and run at line speed.
