Does AI Look At Signals?

[boleyd]

I had a portal emitting trains every 2 minutes. They were set to return to another portal. To get there they had to go through a rail yard. No signals were installed. I was surprised that the trains behaved perfectly. No collisions and no gridlock. Up to 4 trains on the board at one time. If 2 trains approached a switch/junction one always paused to allow the other to pass. If a "old" train was blocking a new train from the shortest route to the destination portal it took an alternate route. Ran for about 30 minutes with no problems.

This seems to indicate to me (not much Trainz experience) that AI may not use, or at least need, signals to function. ???

Trainz will indeed run without signals as trainz looks at each block to determine if it is clear to proceed. Trainz will also read signals so on a long section with no junctions you place several signals, this breaks the block into smaller sections. Without signals only one train per block, with signals one train between each signal = several trains in the same block. This will speed up movement on long sections of track.

On doubletrack yes, on singletrack if you place block signals you will get a standoff.

not if the signals were made right. with TS09 it is possible to have intermediate signals that do not cause this.

All though the AI is floored it has its good parts. A bare minimum for it to function is commands, track and point motors. (If you have junctions)
