Why dtg has stopped implementing coupling slack after Csx and Nec. European trains dont have coupling slack in the game. This does not feel realistic. A long and heavy freight train rigidly starts moving as the loco moves. It was well simulated in csx and nec, making the player feel and hear the jolting caused by slack. Another issue is lack of cab sway in all models. This is letting me down whenever I play the game. I hope you simulate realistic cab sway behaviour for all the routes and locomotives very soon.
