3DTS Cab Forward Wheel Slip

[1996fan]

Does anybody else have issues with the Cab Forwards from 3DTrainStuffs Donner Pass Route having horrible wheel slip issues? I can't get them to move when running explorer mode. In an activity I use the auto pilot to get em started and after they get good and going I take over manually, and as soon as I do the wheel slip pops up. Is it a physics issue with Open Rails? I never had the route when it was just MSTS.

Hi.
Make sure you don't use the fast forward feature (Ctrl + Alt + PageUp). It turns the wheels into wet soaps if advanced adhesion is enabled in OR settings.

The cab forwards are set up in a fairly unusual way that only tricks MSTS but does not work for the more advanced physics in OR. If you want to drive the cab forwards, disable the Advanced adhesion model in the Simulation tab of the Options menu.

Also If I remember correctly the original engine files did not split the weight of the locomotive even close to evenly over the two halves, same goes for the HP ratings almost all of the HP was assigned to the front set of drivers, and very little to the rear ones. I modified all of mine based on how Derek Miller did his WP 2-8-8-2's which is the evenly split the total wright and HP between the two halves of the engine

Below is a link to a 2023 thread that dealt with this issue and it has some solutions

Darkhorse is correct, making both sets of drivers the same weight seems to have solved the issue. I think the old thread mentioned 150ton per set

Thanks that fixed it.
