The invention provides a locomotive signal power module which comprises a direct current converter, a safety switch and a drive circuit. The drive circuit controls on-off of the safety switch according to a control signal of a mainboard CPU. On or off of the safety switch controls a series relay set to be at a power-on working state or a power-off state. The locomotive signal power module can turn off all lamp positions of a signal machine when a locomotive signal system fails and inform drivers that the locomotive signal system fails, and therefore safety hazards caused by failures of the locomotive signal system are eliminated. 本发明种机车信号电源模块，包括直流转换器，安全开关，驱动电路。驱动电路根据主机板CPU的控制信号控制安全开关通断；安全开关的导通或断开控制串联继电器组处于上电工作状态或断电状态。本发明的机车信号电源模块，能够在机车信号系统发生故障时关闭信号机的所有灯位，告知司机机车信号系统已发生故障，从而消除因机车信号系统故障引起的安全隐患。
