On my laypout I have two grades of about 3.5%, which lead up to a bridge (the layout is a figure 8 configuration). One is straight and the other curved most of the way (the standard 195 mm and 220 mm curves). My E44s will pull a 5 coach D zug train up the straight grade, but they struggle on the curved grade.
