The invention provides an optical signal receiving assembly for a train, an optical signal receiving system for the train and the train, and relates to the technical field of optical communication of ground-on-board equipment. The receiving surface of the first group of light receivers directly faces the front of the train; the receiving surface of the second group of light receivers inclines to the side surface of the train by a first angle; the receiving surface of the third group of light receivers inclines towards the side surface of the train by a second angle. Due to the fact that the inclination angles of the three sets of light receivers are different, it is sequentially met that in the process that the distance between the train and the annunciator changes, it is guaranteed that at least one light receiver is roughly opposite to the annunciator, enough light signals can be received, and signal support is provided for safe operation of a system. 本发明提出一种列车用光信号接收组件、列车用光信号接收系统和列车，涉及地面-车载设备光通信技术领域，该光接收组件包
