This scenario starts off with you pulling a long, heavy (nearly 5,000 ton) coal train with a trio of SD40s up a 1.5% grade in a blowing snowstorm. Going above notch 3, even with the sanders on, always results in wheelslip, so you're stuck at notch 3, crawling up the grade at all of 0.6 mph. I'm certain I'm not dragging my brakes, and all three locos show they're pulling (or are at least making appropriate current). Is there something I'm missing here, or do you really have to wait like an hour until you can finally throttle up?
Also, remember that all services exist outside of journeys, something the game does a poor job at telling people. You can select this service from the timetable and set it up with different weather or a different season. This was a problem with SPG where a service was in the journey with snowy weather and was near impossible to complete. Many of us suspect it was only tested in the timetable rather than the conditions specific to the journey.
