BS 70A Hlau Rail
Steel rails, tseem hu ua rail rail, railroad rail, los yog lub tsheb ciav hlau lem, yog ib qho tseem ceeb Cheebtsam ntawm railway systems. Lawv muab lub hauv paus ruaj khov rau cov tsheb ciav hlau mus ncig, tsim los tswj cov khoom hnyav thiab tiv thaiv hnav. BS 70A Rail yog ib txoj kev tsheb ciav hlau uas nquag siv uas ua tau raws li cov qauv hauv tebchaws Askiv (BS). Nws muaj qhov hnyav ntawm 34.807 kilograms ib 'meter'.
Raws li ib tug sab saum toj steel rail chaw tsim tshuaj paus nyob rau hauv Tuam Tshoj, peb paub txog peb tshwj xeeb zoo thiab kev sis tw nqi ntawm tej kev txiav txim. Peb cov khoom ua raws li cov qauv kev lag luam nruj, thiab peb muab cov kev daws teeb meem los ua kom tau raws li koj cov kev xav tau tshwj xeeb. Nrog cov kev xaiv hloov tau yooj yim rau kev hloov kho, peb xyuas kom meej tias peb cov ntsia hlau ua tau raws li koj cov lus qhia meej. Peb zoo siab tos txais cov tib neeg thiab cov koom haum los ntawm txhua qhov chaw tuaj yeem tiv tauj peb kom paub ntxiv thiab sib tham txog cov peev txheej sib koom tes.
