Abstract
An apparatus and method for rail inspection include a inspection carriage that moves atop a rail and carries a rail height sensor directed toward the rail. The rail height sensor generates a signal correlated with a vertical position (height) of the rail relative to the carriage as the carriage moves along the rail. A signal processor converts the rail height signal to a log of rail heights along the rail. Further processing of the log, e.g., in the signal processor, identifies crushed head defects in the rail.
