Raws li ib feem tseem ceeb ntawm txoj kev tsheb ciav hlau, steel rail muaj lub luag haujlwm los coj lub tsheb ciav hlau, dais lub siab loj ntawm lub log, thiab kis tau lub siab mus rau cov neeg taug kev tsheb ciav hlau. Hais lus technically, lub dov nto ntawm steel rail yuav tsum tas mus li, du thiab tsis tshua muaj zog los txhawb lub tsheb ciav hlau log.
International qauv ntawm steel rails
