I was running a San Diegan activity from SD to LAUPT this afternoon and I was being lazy and running in Autopilot. I noticed that the train was really early at all of the station stops, having up to 6-7 minutes passenger loading times. After leaving San Juan Capistrano I decided to test something. The grade from Gallivan to El Toro is 67.3 feet per mile, or 1.6%. Speed limit for this stretch is 90 MPH. Running two 1500 HP F-units pulling 7 lightweight passenger cars, Autopilot had 'em pegged at 88.3 MPH all the way up. Switch out of Autopilot and reality returns: 68 MPH and struggling to make the grade with this load. Switch back to Autopilot and power sucks in out of the ether and right back up to 88.3! Quickly! Acceleration from station stops also seems to be more jack rabbit than locomotive.

Any way to tone the power settings down a bit to be more realistic? :bigboss:

Autopilot can pull almost everything. I tested it before on 10,000 ton coal up Cajon pass an 2 MP15DC’s pulled it to track speed in AutoPilot to Summit but at least it didn’t break a knuckle.

Autopilot uses the physics of AI trains and runs with 0.95 efficiency. Changing autopilot physics requires changing AI train physics, and that can have negative consequences.

I wondered if that were not the case. I guess you don't want AI's stalling out on the grade eh?

I also guess that if I'm going to be lazy I should expect to put up with certain shortcomings! :lol: :bigboss:

If you take it off of autopilot it stalls out, right?

Yep.

It’s almost like a cheat code where if your stalling to turn on the staroids of autopilot.

LOL! But how do you snarl up the whole railroad with that kind of strategy. :rotfl: :bigboss:
