In a method of train deceleration, a train computer: (a) causes brakes of the train to be set according to a target deceleration curve, profile, or braking model estimated to decelerate the train from a present speed at a present location to a target speed at a target location; (b) during deceleration of the train according to the target deceleration curve, profile, or braking model of step (a), determines an actual deceleration curve of the train; (c) in response to determining from the actual deceleration curve that the train will overshoot the target speed at the target location, determines another target deceleration curve, profile, or braking model estimated to decelerate the train to the target speed at the target location; and (d) causes the brakes of the train to be set according to the other target deceleration curve, profile or braking model of step (c).
