And everything you do costs. Getting rolling with wheelslip? Whjeels will wear down faster. Managed to havew not enough swing when goiun g into the climb? You pay by needing to spend for sand, and more Diesel. Energy management. I say again: energy management. Do mnot anticipate your haul correctly,. and find yourself ending up with entering the station from a side where you cannot easily dsort your waggons, or your locomotive being on the wrong end of the train. This all is as relaxed, in a way like ETS2 or ATS, but has an awsome lot of challenge more to it. Easy it is not. Its not Train Simualtor and its not Trainz.
And everythign costs. Everything.
Mess up too many things, waste too much money needlessly, and see your career derailing in the reds.
