I (think I) understand operating a steam loco. Using the lead as a velocity controller, water and coal little but often. Not having more than 70-80% of neither, using the fan at slow speeds - Still I am not able to bring my trains up the hill (Trainz simulator 2, Mac, Murchinson).
What am I missing? Would be good to know if there is an ideal operating these machines that was readable somewhere..
Help please (Not very into gaming, but into (real) trains.
