A dual mode brake control system of a locomotive and a locomotive comprising the same. The dual mode brake control system of the locomotive comprises a relay valve (1) and a balanced pressure controller (2), and further comprises a mode change-over valve (3), an electrical interlocking change-over plug valve (5) and a brake controller (6). When the electrical interlocking change-over plug valve (5) is in a triggered state, an air inlet and an air outlet thereof communicate with each other, otherwise the air inlet and the air outlet thereof are cut off; and when the electrical interlocking change-over plug valve (5) is triggered, the brake controller (6) enables an air outlet and a second air inlet of the mode change-over valve (3) to communicate with each other, otherwise the air outlet and a first air inlet of the mode change-over valve (3) are enabled to communicate with each other. In the described system, the brake controller (6) may control the braking mode of the mode change-over valve (3) under the state change-over of the electrical interlocking change-over plug valve (5), and thus freely switching between an independent braking mode and a backup braking mode may be achieved without needing to provide a backup brake controller as well as an additional air circuit for the backup braking mode, so as to avoid occupying extra space and reduce the wiring complexity of the brake system.
