The invention relates to the technical field of rail transit, in particular to a train braking control method and system. The method comprises the following steps: acquiring current running data of a train; wherein the operation data comprises the speed, the acceleration of the equivalent gradient and the operation distance; based on the operation data, a preset train control level delay period and historical levels in a preset configuration table, the predicted distance and the predicted speed of the train are obtained; based on the predicted distance and the predicted speed, acquiring an acceleration reaching a target position and a target speed; based on the accelerated speed, a preset configuration table is used for obtaining a level matched with the acting force of the ATO for controlling the train; wherein the types in the preset configuration table at least comprise the delay period, the acceleration and the level of each preset vehicle control level, and the delay period, the acceleration and the leve
