The invention relates to a vacuum sanitary system for railway vehicles, which comprises a waste water discharge device, a toilet stool, a flushing device, a vacuum generator, a toilet stool flushing trigger switch, a transfer box, a sewage box and a control unit, the transfer box is connected with the vacuum generator, and the waste water discharge device is connected with the transfer box through a drain pipe. A one-way valve and a diaphragm valve are connected in series on the drain pipe, wastewater flows into the transfer box through the one-way valve and the diaphragm valve under the action of gravity, the transfer box is mounted above the sewage box, a transfer box blow-down valve is mounted at a communication port between the transfer box and the sewage box, and sewage in the transfer box is discharged into the sewage box under the action of gravity. The toilet flushing trigger switch comprises an excrement trigger switch and a urine trigger switch, and the excrement trigger switch, the urine trigger switch, the transfer box blow-down valve, the flushing device and the vacuum generator are connected with the control unit. The system is simple in overall structure and low in cost, the control mode is simplified, fault points are reduced, the reverse spraying risk of the transfer box is eradicated, the working reliability of the system is greatly improved, and meanwhile the electricity consumption, the water consumption and the gas consumption of the system are reduced.
