Sleepers The members which are laid transverse to the rails on which the rails are Supported and fixed to transfer the loads from rails to the ballast and sub grade below. Functions 1)       To hold the rails to correct gauge. 2)       To hold the rails in proper level. 3)       To act an elastic medium in between ballast and rails. 4)       To distribute the load from rails to index area of ballast underlying it. 5)       To support the rails at a proper level in straight tracks and proper super elevation on curves. 6)       It also gives lateral and longitudinal stability of the permanent track. 7)       To rectify the track geometry during service life. Requirement        i.           They should be economical i.e...

Different Types Of Rail Joint Rail Joint Definition Encyclopedia has defined the word “rail joint” as the following: A splice connecting the adjacent ends of rails, in distinction from a chair, which is merely a seat. The two devices are sometimes united. Among several hundred varieties, the fish joint is standard. See Fish joint, under Fish. Rail joint plays a jointing function (connecting function) in the railroad. High quality railway joint can effectively reduce the influence of wheels when passing through the jointing sections of the steel rail and increase the steadiness and continuity of the passing trains. As one of the important parts in railway, railway joint bar are widely used both in light rail and heavy rail to guarantee the safety of railroad transportation. Rail joint for light rail: 8kg, 9kg, 12kg, 15kg, 18kg, 22kg, 24kg and 30kg Rail joint for heavy rail: 38kg, 43kg, 50kg and 60kg Rail joint for crane rail: QU70, QU80, QU100 and QU120 Different Typ...
