Thanks for spending the time to explain the internals. But I am afraid that is not the subject I am asking for. May be we get closer if I ask the other way around.
Scenario:
You run a train at level terrain (in any notch:-) with constant 28mph since at least 5 minutes. You want to accelerate to 30mph because that is the max permitted speed.
What do you do?
1. Go up one notch
2. ... ? what happens ? I assume the train will accelerate to a speed higher than 30mph? But you shall run 30mph!
ps. To do the same with your car you would press the accelerator pedal very very gently to get 2mph more speed. But you would not press the pedal 1/8 more down just for 2mph.
