1. A method of substantially achieving a minimum stopping distance of a freight train consist without incurring any significant detrimental wheel slide, said method comprising the steps of:

  • (a) preprogramming preselected information into a computer disposed on a freight locomotive;

    (b) determining a speed of such freight train consist;

    (c) communicating a signal that is indicative of said speed determined in step (b) to such computer disposed on such freight locomotive;

    (d) determining in such computer a pressure that can be applied to brake cylinders which will maintain substantially maximum adhesion between wheels being braked and rail surfaces in contact with such wheels;

    (e) communicating a signal representative of such pressure determined in step (d) to a pressure control valve in fluid communication with such brake cylinders; and

    (f) maintaining a maximum pressure on such brake cylinders that will stop such train consist in a shortest possible distance while simultaneously substantially preventing wheel slide.
