PROBLEM TO BE SOLVED: To provide a snow resistant braking device for a freight car that can be mounted on a freight car.SOLUTION: There is provided a snow resistant braking device 2A for a freight car that performs snow resistant braking for a freight car 12 connected to a locomotive 11. The freight car 12 is provided with a brake cylinder 32, a BC pipe (air duct) 31 connected to the brake cylinder 32, an electromagnetic valve 21A for opening/closing the BC pipe 31, and a pressure detection part 22A for detecting the pressure of the brake cylinder 32. The locomotive 11 is provided with a snow resistant brake switch 23 for switching ON/OFF of the snow resistant brake, and a brake command detection part 24 for detecting ON/OFF of a brake command of the locomotive 11. A snow resistant brake command line 25 for supplying a voltage from the locomotive 11 to the freight car 12 is disposed between the locomotive 11 and the freight car 12, and when the pressure of the brake cylinder 32 detected by the pressure detection part 22A satisfies a predetermined condition, a voltage is supplied from the snow resistant brake command line 25 to the electromagnetic valve 21A.

    【課題】貨車に搭載することができる貨車用耐雪ブレーキ装置を提供する。【解決手段】機関車11に連結される貨車12の耐雪ブレーキを行う貨車用耐雪ブレーキ装置2Aであって、貨車12には、ブレーキシリンダ32と、ブレーキシリンダ32に接続されたBC管(空気路)31と、BC管31を開閉する電磁弁21Aとブレーキシリンダ32の圧力を検知する圧力検知部22Aと、が備えられ、機関車11には、耐雪ブレーキのON・OFFを切り替える耐雪ブレーキスイッチ23と、機関車11のブレーキ指令のON・OFFを検知するブレーキ指令検知部24と、が備えられ、機関車11と貨車12との間には、機関車11から貨車12へ電圧を供給する耐雪ブレーキ指令線25が配設され、圧力検知部22Aが検知したブレーキシリンダ32の圧力が所定の条件となると、耐雪ブレーキ指令線25から電磁弁21Aに電圧が供給される。【選択図】図2
