CIVIL ENGINEERING MAINTENANCE WORK

Regular examination is the basis of railway civil engineering maintenance work, ranging from daily examination of passenger-carrying lines to underwater examination of the piers or abutments of a bridge at 20-year or longer intervals. The Matisa track-recording self-propelling trolley unit, introduced during the last two years, enables reliable records of cross level, track curvature and track gauge to be obtained at a running speed of about 20 mph. Examination of rails with manually-applied ultrasonic-type flaw probes was introduced in 1954. A special rail-mounted adaption of the principals and mechanism of the Simon hoist has been developed to provide better means of regular examination of high masonry vaiducts. At the end of 1958, only two major equipment developments were being pursued. First, a prototype "on track" self-propelling machine was under construction. This is designed to excavate track ballast from outside the ends of sleepers, and screen it, and replace the clean ballast. Secondly, a design of a type of low-loading lorry with both pneumatic-tired road wheels and steel flanged tired wheels is being developed.
