The invention provides a transmitter 1+1 redundant track circuit system suitable for a general speed railway. The track circuit system comprises N track section circuits, wherein each track section circuit comprises a main transmitter, a standby transmitter and a coding circuit, and the main transmitter and the standby transmitter of the same track section circuit are connected with the coding circuit through the same group of relay contacts. The transmitter 1+1 redundancy track circuit system suitable for the general speed railway is advantaged in that reliability of the system is effectivelyimproved by setting the transmitter 1+1 redundancy and controlling two transmitters by the same group of relays, moreover, accurate positioning of a track circuit is realized by setting a 1+1 redundancy diagnosis system, and maintainability of the system is improved. 本发明提供一种适用于普速铁路的发送器1+1冗余轨道电路系统，所述轨道电路系统包括N个轨道区段电路，每个所述轨道区段电路包括：主发送器、备用发送器及编码电路，同一个所述轨道区段电路的主发送器和备用发送器通过同一组继电器接点与所述编码电路连接。本发明的适用于普速铁路的发送器1+1冗余轨道电路系统通过设置发送器1+1
