British Railways have designed radial arm equipment for guaging the clearance of structures near track which consists of (a) the radial arm unit comprising a carrier beam, a graduated disc, and a telescopic arm; and (b) the pedestal unit, upon which the radial arm is mounted; the latter unit registers with the running edge of the rail adjacent to the structure to be profiled. The advantages claimed for this type of equipment are summed up as follows: (a) greater accuracy; (b) speedup of measurements on site; (c) fewer site dimensions required; (d) reduced track occupation; (e) simplicity in computation of results; (f) reduction in drawing office time plotting; (g) constant result from running edge of rail adjacent to structure.
