A control system and method for the pressure of a train pipe of a locomotive. The control system comprises a main air pipe; a relay valve, an input port of which is connected to the main air pipe; a train pipe, which is connected to an output port of the relay valve; an equalizing reservoir, which is connected to a control port of the relay valve; a first solenoid valve, which is connected to the main air pipe and the train pipe; a second solenoid valve, which is connected to the train pipe and the atmosphere; a first pressure switch, which is connected to the first solenoid valve; and a second pressure switch, which is connected to the second solenoid valve, wherein the first pressure switch can be closed when the pressure of the equalizing reservoir is greater than the pressure of the train pipe, such that the first solenoid valve is powered on to connect the main air pipe to the train pipe; and the second pressure switch can be closed when the pressure of the train pipe is greater than the pressure of the
