The amplifier unit is basically a six channel self-balancing push-pull amplifier which will accept symmetrical and asymmetrical inputs. The outputs of the six amplifier channels are fed to six cathode ray tubes. The indications on the cathode ray tubes may be recorded simultaneously on photographic paper. The equipment has been used on a variety of projects. The recording equipment is used for the measurement of the rail bending stresses set up in bull head and flat bottom rails due to the passage of vehicles. Tests involving the measurement of stresses set up in an L.T.E. bogie frame gave useful information regarding stresses under static and dynamic conditions. The equipment has also been used for development tests on electrical equipment for multiple unit trains.
