Abstract: A railway nipper machine is provided that includes a nipper frame having a pair of nipper hooks for performing a nipping operation, and a position feedback device having a central control module configured for controlling the nipping operation based on a depth signal and a time signal. Further included in the nipper machine is a depth sensor connected to the position feedback device for generating the depth signal relative to a nipper actuator connected to the nipper frame, wherein the depth sensor transmits the depth signal to the position feedback device. A timer is provided for generating the time signal, and 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.

Abstract: A rail fastener orienter is provided for orienting rail fasteners to a desired orientation, the fasteners having a head, an opposite tip and a shank connecting the head to the tip, and being sequentially provided to the orienter in one of a head right, head left, head up and head down orientation. The orienter includes a frame having an upper end and an opposite lower end, and defining a track with an inlet adjacent the upper end, and an outlet adjacent the lower end, the track dimensioned for slidingly and rotatingly accommodating the shank. At least one stage holder is provided for accommodating the fastener in the track as the head is at least partially engaged by at least one bumper for repositioning to a desired one of the orientations, such that the fastener reaches the outlet in the desired orientation after axial rotation.

Abstract: A propulsion control system is provided for controlling a hydraulic drive system of a railway maintenance vehicle. An axle monitoring module receives and monitors a first signal from a first rotation sensor, and a second signal from a second rotation sensor, the first and second signals associated with first and second axles of the vehicle, respectively. A speed comparison module calculates a delta value representing a difference between the first and second signals, and generates a speed control signal based on the difference. A speed control module receives the speed control signal, and generates a power signal for controlling an amount of power applied to at least one of the first and second axles based on the speed control signal. An actuation control module receives the power signal, and performs a power allocation function for controlling a speed or power of the hydraulic drive system.

Abstract: An automatic rail spike feeder system for use with a rail maintenance vehicle having a bulk storage bin for containing a supply of spikes, and at least one spike driving mechanism, includes a mechanism constructed and arranged for receiving a supply of spikes from the storage bin and for automatically delivering individual spikes to the at least one spike driving mechanism in a desired orientation without operator contact with the spikes.
