Hi, Rhein-Ruhr Osten, Journey, Chapter 2 (Freight), Item 12 (Petroleum from Hagen to Wuppertal-Steinbeck of 15:50 on a BR185.5MRCE, 21 tank cars): Impossible to complete: impossible to climb the second 1,7% hill. Wheels keep slipping if power is too high (therefore power must be kept at max 75%), finally the train slows down, stops, and finally go down. Ride failed It worked it Train Sim World 2020, but fails in Train Sim World 2 (introduction of the physic engine) as of 2021-04-11.
I submitted a ticket on this back in March, it has been passed onto the Development Team. Hopefully something is done to fix this.
It is still possible to complete the service in journey mode. Just cut off part of your train. When you get to the end, it will say invalid consist, but it will still complete the service.
I just ran into this issue myself. Tried it two times before giving up. Did you get any feedback on your ticket graeme.norton1 ?
