The basic principles of work study and two of its sub-divisions, method study and work measurement, are briefly descriptionbed. This is followed by a discussion of labour control and incentive schemes, with reference also to the signifiicance of such schemes to a large railway undertaking in general, and permanent way maintenance in particular. Work values, performance rates and the value of labour control and incentive schemes are briefly discussed.
Although fairly new in South Africa, long welded rails have been in use for many years in other countries and experience has shown that they are a practicable proposition provided certain precautions are taken. The paper descriptionbes briefly what is Involved from the practical aspect in laying and welding rails into continuous lengths. It covers the tests that have been carried out in this country to determine the thermal stresses generated in long rails. Tests for buckling and lateral rigidity of the track are also dealt with.
The main purpose in mechanizing track maintenance and renewals is greater efficiency by means of doing the work more economically or to obtain a higher standard or both. This purpose Iis achieved through the use of power driven machines and ancillary equipment to eliminate or replace hand labour. A descriptionption is given of the requirements of track maintenance, the methods adopted to achieve this with mechanized gangs, the mechanized equipment being used, the erection of mechanized repair depots, and the methods adopted to determine gangers' lengths for mechanized and nonmechanized gangs with due consideration to factors such as classification of the various lines, number of trains, position of gang headquarters, standard of permanent way material, condition of formation, etc. In conclusion a brief summary is given of the economical and other Indirect advantages to be gained by mechanization of track maintenance and renewals on the South African Railways.
The new station is to be built to replace a station completed in 1932. Since that date the number of passengers using the station has more than quadrupled, while the Reef population has doubled. The station will be of the through type and will have 16 passenger platforms and two through tracks for goods trains. There will ultimately be six approach tracks at either end of the station. The track ladders at the ends of the station will be at an angle of I in 7 to the main lines and I in 7 outside slips will be used for connecting to the various platform tracks.
