RailPro has a full compliment of engine settings under the tools button for each loco. Each loco is tweaked and those setting are saved. No CV's to deal with. Then dial in a "load" setting for your train, 0 to 100%. This algorithm takes momentum to the next level as it simulates pulling a load by adjusting speed and sounds together. There is a delay as the engine starts to pull, prime movers rev up and the engine breaks away with the train. Nice rolling starts and stops can be done.
