This examples demonstrate a locomotive plus several wagons performing a drive cycle, powered by the external speed source.
Investigate as a function of time:
vehicle.s = vehicle distancevehicle.v = vehicle velocityforceSensor.f = traction force required to move the vehicle,
forceSensorLW.f = drag force between locomotive and (first) wagonpowerSensor.power = power required to move the vehicleenergy.y = energy required to move the entire train
