AI Drivers & Speedlimits

[Danieldd4]

I'm new so bare with me. Ive looked for this a maybe missing it. I have a route that in most places has the speedlimit set to 65. However when the AI drivers are running they will only drive at 35mph. Is there a global speed setting or something that I maybe missing.

Thanks for your time

From what I have learnt there are yellow lights and red lights and all kinds of stuff for A1 to watch, and I think an example is two yellows mean caution and that there is possibly a red light next, and then you have trains running at half speeds etc.

You might what to check the locomotives configs file enginespec kuid, open the enginespec's confg and look for max speed tag, increase it;

motor
{
resistance 1.7
adhesion 2.5
maxvoltage 600
maxspeed 33 change to 65
brakeratio 55000
max-accel 2500
max-decel 9000
axle-count 4
surface-area 150
moving-friction-coefficient 0.01
air-drag-coefficient 0.0001
throttle-notches 8
full-throttle-speed 33 change to 65
}

Yes Yes I am sorry maybe I was not clear..... With all green they are diving at 35 mph sorry....

Ok I will check this but if max speed was set to 35 why would I be able to drive it faster... ie. this is only happening with AI drivers..

This has a lot to do with the signaling. The AI drivers will drive at caution speed which is about 1/2 speed when they cannot see a signal, or if there is a junction ahead. I have found that if I place Type 05s along the line before the junction, which has a type 04 and type 06 combination, that the AI will operate at the posted speed.

My signaling pattern is like this starting with a single to two-track line:

Type 06 facing towards the singla track------ Type 04 on both tracks, facing towards the double track side, then Type 05s facing both ways with one on each track, repeating until I reach the next double-to-single track.

I space my signals about the length of the 3000t US coal train. I use this as my sliding ruler and place the signals roughly at the end of the consist.


Another thing that will cause the AI to operate at the 1/2 speed is a junction facing the wrong direction. If you align the switch properly, then the AI will drive at full speed, but ensure you have the signals in between as well because the AI will default to 29 mph when they approach crossovers and junctions that are protected by type 06s and type 08s.

these values are in meters per second and are fast enough in most cases 33 mps = 74 mph.

John is on the right track there (no pun intended...) but if you read this http://trains.0catch.com/Sometimes%2035%20is%20faster%20than%2060.pdf it may help explain things for you. Or possibly confuse you totally!

It has been my experience with T10 & T12 that these values, mps will no covert to mph. There is a tread somewhere on the forum that covers this problem.

Thanks for your time... It seems I had a switch thrown that was indeed causing a yellow signal. In turn causing train to run at 1/2 speed.
