Rails yog siv nyob rau hauv railway systems raws li lem rau tsheb ciav hlau mus ncig teb chaws. Lawv nqa qhov hnyav ntawm lub tsheb ciav hlau, muab txoj hauv kev ruaj khov, thiab xyuas kom lub tsheb ciav hlau tuaj yeem ua haujlwm zoo thiab ua haujlwm zoo. Steel rails feem ntau yog ua los ntawm cov hlau muaj zog thiab muaj peev xwm tiv taus hnyav thiab siv tas li, yog li lawv ua lub luag haujlwm tseem ceeb hauv kev tsheb ciav hlau.
Steel rails feem ntau yog siv nyob rau hauv railway systems, xws li high-speed railways, intercity railways, subways, lub teeb rails, freight railways thiab lwm yam railways. Tsis tas li ntawd, steel rails kuj tseem siv tau rau qee lub sijhawm tshwj xeeb, xws li nqaim-gauge railways hauv mines thiab tshwj xeeb railways hauv factories. Zuag qhia tag nrho, rails yog ib feem tseem ceeb ntawm txoj kev tsheb ciav hlau thauj mus los.
