The invention relates to the technical field of signal lamps, and discloses a railway signal lamp capable of automatically cleaning dust on a lamp surface, which comprises a support column, a sleeve is fixedly connected to the left side of the support column, the lamp surface is arranged in the sleeve, a filter block is arranged on the surface of the sleeve in a penetrating manner, and a bearing block is arranged above the sleeve. A plugging block is arranged at the top of the bearing block in a penetrating mode, an extrusion air bag is arranged below the plugging block, an air plate is rotationally connected to the left side of the one-way toothed plate, a limiting toothed rod is fixedly connected to the left side of the air plate, the side face of the limiting toothed rod is in engaged connection with a limiting toothed plate, and an ejector rod is rotationally connected to the side face of the limiting toothed plate. A rotating wheel is rotationally connected to the side, away fromthe limiting toothed plate, of the ejector rod. According to the signal lamp capable of automatically cleaning the dust on the lamp surface for the railway, through cooperative use of the screw and the reset gear, the effect of automatically cleaning the dust on the lamp surface of the signal lamp when a train passes through the signal lamp is achieved.
