Project Overview

Project Number


A device known as a Railhead Gauge was developed to measure and record the profile of the head of a rail while that rail was in-situ in an operating railway.

The data are recorded on a solid state memory module which can be removed from the recording device and transferred to a computing system for analysis and preparation of graphical or tabular results.
