The invention provides a ventilation device and a rail vehicle, the ventilation device is installed on an oil tank of an internal combustion engine power or hybrid power rail vehicle, the ventilation device comprises a first pipeline, a second pipeline, a third pipeline and a switching assembly, the first pipeline is installed above the oil tank and communicates with the oil tank, and the second pipeline is installed above the oil tank and communicates with the third pipeline; one end of the second pipeline is connected with the other end of the first pipeline, and the other end extends downwards along the height direction; one end of the third pipeline is connected with the other end of the first pipeline, and the other end extends upwards along the height direction; the switching assembly is installed among the first pipeline, the second pipeline and the third pipeline and is suitable for enabling the first pipeline to communicate with the second pipeline under the condition that the railway vehicle runs normally so as to balance the internal pressure and the external pressure of the oil tank. And under the condition that the railway vehicle accelerates or decelerates, the fuel oil rising along the first pipeline in the oil tank pokes the switching assembly, so that the first pipeline is communicated with the third pipeline.
