TRACK MAINTENANCE FOR HIGH-SPEED TRAINS
To prepare its mainlines for high-speed trains, British Railways has made changes in track structures and track maintenance. Evolution to the present design of concrete cross tie and rail fasteners is described, and the conversion to welded rail is discussed. The depth of ballast was increased and the quality standards improved. The maintenance machines and maintenance techniques have also been altered. Brief mention is made of glued joints, rail welding, manual/mechanized ballast packing, rail drilling and sawing, and rail destressing and restressing.
