I just notice when I try to lift a coal train from a dead stop on dry rail on level grade with 2 AC4400 locos from SLI on the headend and a 110 coal gonds back a dpu unit pushing I get a wheelslip indication as soon as I put the unit in throttle 1 or 2. Not working a whole lot of power and yet the wheelslip comes on.
I was curious if any programming was being undertaken for modeling AC traction physics? Instead of a constant wheelslip, a wheelslip is sensed and power is derated to keep in the traction threshold.
Thanks In advance

A question to ask beforehand, can run 2 give you wheelslip on level grade and dry rail in reality?

Hi,
just a quick answer - you can set Antislip ( 1 ) in the ENG file and force the simple adhesion model to be used. It is not clear solution yet, because it will not limit the tractive force - it will act like the MSTS adhesion model and running into a wheelslip will reduce tractive force. If you don't mind, you can use the Sander to cancel the wheelsip.
I'll have a look on what I can do with it. It will be a saturation of the wheelslip percent at 90%. We are not able to code the real-world antislip control system, as it requires much more real-time programming, what cannot be done on Windows...

Now I´ve got to ask one more question: What exactly does AntiSlip() (enabled or disabled) do in both MSTS and ORTS?

Thanks for the input. I didn't know that the AntiSlip(1) line would work but it did when I looked through my .eng file for the SLI unit I had for leadunit I found that it didn't have the AntiSlip line in the eng file so I added it. I disabled the Advance Adhesion setting and was content with not getting that alarm buzz that the unit was slipping. I did need a shot of sand to get rolling for the first couple mph then it slowly chugged up to track speed. I'm a happy camper.
