Claim:
1. A railway nipper machine, comprising: a nipper frame having a pair of nipper hooks for performing a nipping operation; a position feedback device having a central control module configured for controlling the nipping operation based on a depth signal and a time signal, wherein the central control module includes a depth comparison module configured for determining whether a predetermined depth relative to the nipper actuator has been reached within a predetermined time period based on the time signal and the depth signal; a depth sensor connected to the position feedback device for generating the depth signal relative to a nipper actuator connected to the nipper frame, the depth sensor transmitting the depth signal to the position feedback device; a timer that generates the time signal; and wherein the nipper machine is actuated by the nipper actuator in response to a determination value generated by the position feedback device based on the depth signal and the time signal.
