Hello

is there a simple way or formula to calculate the maximum speed of the convoy, according to the locomotive power, torque, and load quellle shoot? (Disregarding the constraints of the rails, or max speeds of the cars?)

I want to make a quick simple program showing the kind of optimum convoy entering the date, type of freight, the amount per month, etc. ...

But I would need a simple way to calculate the maximum speed ...

Thank you!
