The utility model discloses a railroad sleeper fixing fastener. The railroad sleeper fixing fastener comprises anchoring parts embedded into a sleeper, gauge aprons, elastic bars, screw spikes and nuts, wherein one side of each gauge apron is pressed against the sleeper, and the other side of each gauge apron is pressed against the rail bottom side face of a steel rail; the elastic bars are pressed against the gauge aprons; the screw spikes pass through the elastic bars and the gauge aprons in sequence, and are fixed in the anchoring parts; the nuts are screwed on the screw spikes, and are pressed against the elastic bars. The railroad sleeper fixing fastener has the advantages that the steel rail is fixed on the sleeper by using two groups of fixing fasteners, and the gauge aprons are compressed through the screw spikes in each group of fixing fasteners, thereby fixedly supporting a lower rail on one side of the steel rail. The gauge aprons can be compressed more tightly through the elastic bars. The railroad sleeper fixing fastener is simple in structure, and is convenient for construction and maintenance. Moreover, the steel rail is high in stability.
