Abstract
A rail fastener driving machine used for performing a spiking operation is provided, and includes a rail fastener workhead unit configured for driving a fastener into a rail tie. Also included in the machine is a position feedback system configured for controlling the spiking operation of the fastener driving machine based on a position signal and a mode signal, and a position sensor connected to the position feedback system for generating the position signal relative to a cylinder connected to the workhead unit, the position sensor transmitting the position signal to the position feedback system. The mode signal indicates an operation mode selected by an operator, and the workhead unit is actuated by the cylinder based on the mode signal for automatically positioning the workhead unit for driving the fastener into the rail tie.
