ELEMENTS OF RAILWAY TRACKS ELEMENTS OF RAILWAY TRACKS A railway track is a combination (iii) On curves proper superelevation should be provided to the outer rail. 0000011063 00000 n The railway track is a permanent way for all trains. As a professional rail components manufacturer, AGICO Rail can custom any component parts of railway track with national standards. Because industrial trackwork often handles lighter loads at slower speeds than mainline railroads, industrial turnouts are constructed with lighter materials and components. 0000003274 00000 n 0000030032 00000 n For clarity it is often referred to as railway track (British English and UIC terminology) or railroad track (predominantly in North America). It is used to bear the load from the Sleepers, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track … 3 Careful selection of rail track components, the use of competent tracklayers and installing the track to a suitable specification will enhance safety and significantly reduce future maintenance needs. per pair Stock length 39’0” Unitrac Railroad Materials Inc.
