THE RAILWAY TRACK: PRESENT STATE OF DEVELOPMENT AND FUTURE REQUIREMENTS

The DB annually spends more than 100 million DM on the purchase of new rails for tracks and switches, of which rather more than half goes on the UIC 60 profile rails and the rest on S 54 rails. Some 95 percent of all rails are of 90 A quality, the rest 110. A reduction in internal rail stress and an increase in resistance to fracture are desirable, but procedures to this end that can be employed on a large scale are not available. The phenomena of "shelling" and "head check" frequently occur on the outer rails in curves. A reduction in the microscopic degree of purity--which contributes to this effect--is only possible by way of special treatment of the steel. The occurence of rail corrugations is a phenomenon which changes in the material are practically unable to influence. The evenness of the rails is measured automatically during vehicle passage. Methods of automatically recording surface faults and for automatic dimensional checking are being developed at present.
