The invention discloses a railway track car wheel handle brake device which comprises a wheel positioning and connecting assembly, a brake handle, a brake stay wire, a brake stay wire jacking piece, a reset spring, two cranks, two rotating bearings, two supports and two brake discs. The two supports are connected to a wheel through a wheel positioning connecting assembly, the two brake discs are connected to the two cranks respectively, the locking contact faces of the two brake discs face the two side faces of the wheel of the railway track car respectively, and a reset spring and a brake stay wire ejecting piece are connected between the top ends of the two cranks. The brake pull wire penetrates through the reset spring, and the two ends of the brake pull wire are connected to the crank and the brake handle on the reset spring side respectively. The brake pull wire, the crank and the brake disc are sequentially driven by the brake handle so as to tightly hold the wheel, the overall structure is simple, the braking process is rapid, the stability is good, and the braking efficiency of the railway track car wheel is greatly improved.
