// Actually, on the Pololu MC33926 shield the enable lines are tied together on pin 4 and the
// pins 9 and 10 work as "inverted brake" but as we turn on and off the tracks individually
// via the power pins we above use 9 and 10 as power pins and 4 as "inverted brake" which in this
// version of the code always will be high. That means this config is not usable for generating
// a railcom cuotout in the future. For that one must wire the second ^D2 to pin 2 and define
// the motor driver like this:
//                          new MotorDriver(4, 7, UNUSED_PIN,  -9, A0, 18, 3000, 12)
