I know this falls in the “but does it stop you from playing the game” but its really annoying because the train has so much power you slip constantly… cant click the sander without standing up or hovering ever so carefully at which point you lose schedule. PS4 controller isn't a real hand…
I don't think the sander has any effect in the game on any loco on any route. You just have to be a more gentle on the throttle of the ACS-64 to keep it from wheel-slipping. Keeping the power output effort below 30 was what I used as a guideline.
Not in TSW2020 but it does in TSW2. I only use it on American freight locos starting from a gradient in bad weather conditions.
