Using MaxTractiveForceCurves with Diesel locomotive leads to overloading diesel engine

[Matej Pacha]

Setting the throttle from zero to full at non-zero speed leads to the diesel engine to be overloaded and than the power cannot be produced.

Solution is simple:

1) extension of DieselEngines class with following properties

MaxPowerW - sum of MaximalPowerW for all the diesel engines on the list
MaxOutputPowerW - sum of MaxOutputPowerW for all the diesel engines on the list

2) adding:

if (t > (DieselEngines.MaxOutputPowerW / DieselEngines.MaxPowerW))
         t = (DieselEngines.MaxOutputPowerW / DieselEngines.MaxPowerW);

before:

MotiveForceN = TractiveForceCurves.Get(t, currentWheelSpeedMpS);
if (MotiveForceN < 0)
        MotiveForceN = 0;
