Some trains, like BR146, have many forward gears, and I know higher gear means more power.
But other trains, like 612, 477 have only a few forward gears on the power handle.
Could you please tell me what's the meaning of these gears, like Aus Ab Fahrt Auf, and how to drive them smoothly.
(I don't know is it correct to use "gear" here, sorry for my poor English.)
