How to avoid wheel slip
My problem is that every time I start driving, no matter what engine, I get wheel slip. Is it possible, by settings of some kind to disable wheel slip totally.

Can you post one of your eng files zipped please?
OR version?
What route? -
I have pm'd my email address, could you send me the complete trainset please.
It looks like it will be a difficult one to drive.Comment

I could not find the pm you send but I was told that there are a setting in the experimental option in the OR menu there might have to do with this.Comment

Problem solved.
New computer with very low end graphics card which resulted in very low FPS.Last edited by jan111; 12-16-2017, 08:36.Comment

After intensive test driving everything works perfect with no wheel spin at all. It was an old thread in Trainsim.com forum which came with the solution, but I still wonder how on earth FPS can influence on wheel spin.
Can anyone explain.Comment

Hello,
What is the level FPS that you are seeing? I had some wheel-slip issues in a section of the route with high level of scenario reducing the FPS from 46 (normally) to 29 fps,
Driving 105 cars with 13,858 tons with 8 ES44AC locomotives (4 front and 4 at the middle) in a mountain route with 1.6% grade, several tunnels with precipitation, and my train is not able to climb....
I am going to change the OR configuration for adhesion, ENG and Wag files based on the information that I was reading in others threads to avoid wheel-slip,
But I also would like to know if does any one could confirm that reduction in the FPS (as 29 fps) could affect in having wheel slip? just to remove this possibility of my concern,
Thanks

I got to know from the forum in Elvas Tower that wheel-slip and very low FPS (below 20) was connected. Its a bug in OR. The development team are aware of this issue but haven´t found a solution yet.Comment

Thanks a lot for the info, so I could assum that my wheel slip issue is for other reasons... I would keep exploring for the side of eng, wag and OR configuration parameters. thanks again.

I have noticed that a wheelslip indication happens when OR is performing a function, tile loading for example a wheel slip indication can be triggered.
Pretty simple to diagnose.
If your system is stuttering or has other performance issues, expect wheelslip indication. It CANT be wheelslip if your engine is coasting!

As others said, wheel slip seems to occur when below 20fps or when it's attempting the loading of further items.
However, wheel slip happens a lot on the real thing too, but at least the computer program will give you the indication, some units I've ran, no indication at all, except seeing the digital speedo go over 60 and you are thinking, yea right, I'm doing only 10.
if you are getting wheel slip due to simple weights of the trains, try a bit of sand, and a 10-20 pound set on the independent. Usually helps for the wheels losing traction.

I seem to recall somewhere on ET a discussion about this. It was said there by one of the developers (James?) that physics calculations were tied to framerates i.e. one calc for every frame drawn. Therefore, at low framerates, the physics were rubbish. There were plans to separate the two, but I don't know how far along they areComment

Shawn,
If you have an AC unit at the front with DC units behind, is it the driver who must wait the 10 seconds when dynamics are engaged?Comment
