Recently it has come into some members' attention (including mine) that certain locos/trains/MUs dont seem to react properly to gradients, especially descents/level ground... with how great the first Dutch route has come out to be, this was probably the only issue that kinda stood out for ICM and SNG To be perhaps more specific, most trains in the game react to descents even as little as 0.3% or 0.4%, but mostly as 0.5% or bigger, by slowly gaining speed when coasting... but affected trains/units either dont gain speed or even start losing speed, requiring you to apply a little power to keep the current speed Besides the recent ICM and SNG on Zwolle - Groningen, I also remember the Koln Aachen version of 442 behaving this way, and yesterday, as I was doing a service on ECML, I also noticed this behavior on the 801 EMU (also did some 377 and 387 drives on London Commuter and some 323 services on BCC, those seemed fine) Not sure whether this is intended and prototypical, like when they changed the centrifugal force stuff in simugraph so trains would derail more realistically when overshooting speed by a lot on certain curves, or if there is sth wrong with the physics... I am not great at calculating rolling resistance and such stuff, maybe trains indeed get a lot of drag at higher speeds... it would be nice tho if someone from DTG clarified this, as it would be nice if this aspect of physics was consistent across the board This thread was inspired by the discussion on Zwolle Groningen, but isnt exclusive to that content, so feel free to share your experiences if you encountered this on other locos/trains/MUs in the game
