I build a wagon that trains to pull the exact weight of rolling stock, but it reduces locomotive speed. How do I pass this wagon? So, watch my video:
How do I reduce weight before the train pulls rolling stock?
Why cant you set the rolling stock to a very low density? Is it important to the game that it has a certain weight?
You can try setting density in CustomPhysicalProperties, or if your using a constraint to move the wheels you can try turning up the maxtorque
