TRACK RECORDING ON THE SOUTH AFRICAN RAILWAYS

Four track-recording trolleys, self-propelled by a 65-h.p. gas engine, purchased to mechanize track maintenance on the South African Railways, are described. As it travels along the track at 19 MPH, irregularities are detected by the combined movements of probes and wheel flanges carried on three sets of detector assemblies. The function of the trolley is to record high and low points on both rails, versines (curvature) of both rails, superelevation or cant of the track, twist or skew, gauge variations, recording speed, and mileage.
