The invention discloses a locomotive braking cylinder control device. The locomotive braking cylinder control device comprises a first application valve (2), a second application valve (3), a pressure comparison valve (5) and an air-electric interlocking control valve (1), wherein the first application valve (2) is connected to an automatic braking pre-controlling pipeline; the second application valve (3) is connected to a separate braking pre-controlling pipeline; the pressure comparison valve (5) is connected in parallel with the other ends of the first application valve (2) and the second application valve (3), and is used for comparing the pressures of the first application valve (2) and the second application valve (3) and communicating one side with larger pressure with a braking cylinder; the air-electric interlocking control valve (1) is communicated with the first application valve (2). The air-electric interlocking control valve is connected to an automatic braking pipeline, and only the first application valve is controlled to perform air-electric combination or not; when automatic braking is turned from air braking into electric braking, air of air braking is exhausted. The air-electric interlocking control valve can only act on pre-controlling pressure generated by automatic braking, so that more accurate control is realized, and the comprehensiveness and reliability of braking cylinder pressure control are enhanced. A locomotive comprising the device can realize the advantages.
