The invention discloses track signal acquisition equipment which is applied to a track circuit, the track circuit comprises a first steel rail and a second steel rail, and the first steel rail and the second steel rail are connected with track signal receiving equipment; the track signal acquisition device comprises a first resistor connected with the track signal receiving device; the transformer comprises a primary coil and a secondary coil; one end of the primary coil is connected with the first resistor, and the other end of the primary coil is connected with the track signal receiving equipment; the second resistor is connected with the primary coil in parallel; the third resistor is connected with the secondary coil in parallel; the processing module is connected with the third resistor and used for collecting original voltage signals at the two ends of the third resistor so as to obtain track signals in the track circuit. According to the invention, high-impedance input of signals can be realized, so that disassembly and assembly of devices in the track signal acquisition equipment do not influence original track signals, and meanwhile, too small signal transmission values can be avoided, and the transmission quality of the signals is ensured.
