Great Britain lub tuam txhab kev lag luam uas txuas nrog kev lag luam xws li keeb kwm thiab, feem ntau, cov duab thaij duab. Ib qho piv txwv yog Carlisle Choj nyob hauv Lancaster. Teem nyob rau hauv cheeb tsam Lancashire ntawm qaum teb sab qaum teb, qhov 110m choj hla dej Lune tau nqa tsheb khiav txij li xyoo 1847. Ib qho tseem ceeb ntawm West Coast tus cwj pwm tseem ceeb, nws yog ib feem ntawm txoj kev tsheb ciav hlau London-los- Glasgow.
Tus choj tsheb ciav hlau muaj qhov chaw ntav taw thiab cov neeg taug kev mus rau ib sab, uas tiv thaiv taug kev nrog fencing thiab cov tes tuav. Ua ntej lub cav fencing tau hloov ntau lub sij hawm, tab sis muab kev nyab xeeb kev ntub dej, tau phem heev rusted dua. Network Rail (London, UK), lub koom haum saib xyuas txoj kev tsheb nqaj hlau, xav tau ib qho khoom fencing / cov khoom lag luam uas yuav muab cov khoom zoo nkauj ua ke nrog lub zog siab thaum tsis muaj hnyav kom tsis txhob ntxiv ntau ntxiv rau tus choj. Feem ntau qhov tseem ceeb, cov kws qhia npaj siab xav tiv thaiv kev tiv thaiv, tshem tawm cov kev them nqi dhau los ntawm cov nqi kho vaj tse - kho vaj tsev, thiab thaum kawg, ua tiav kev kho tiav.
Network Rail xaiv Pipex px (Roborough, Plymouth, UK), tsim kev lag luam British, tsim qauv siv thiab tsim kev tsim, tsim cov kua hluav taws uas yuav hloov tau cov hlau ciav hlau thiab cov chaw nres tsheb ciav hlau. Pipex px, tus kws muag khoom rau Strongwell (Bristol, VA, Teb Chaws Asmeskas), qhia txog Strongwell lub npe ntawm daim npog ntsej muag EXTREN Series 525 lub thawv iav / polyester ua qauv hauv cov xim plees xim, nrog rau I-kab, lub log thiab cov kav hlau, muab lub cev thaiv rau lub choj pov tseg. Cov Series 525 sib txuas ntxiv rau cov khoom siv hluav taws kub thiab hluav taws kub (UV) inhibitor. Lub fencing thiab cov xuab zeb tua phom sij yog txij li 1.07m txog 2.44 m siab, thiab tau sib sau ua ke, tom qab ntawd ob tog ntawm tus choj thiab lub taw qhia los ntawm Zaj Lus Cog Lus (Carlisle, UK).
Nyob hauv tag nrho, 564 txoj hlua ntawm lub rooj sib tham FRP fencing tau muab ntsia. Tshaj tawm, ob qho tib si nruab nrab thiab cov neeg siv yuav xaus zoo siab nrog qhov kev ua tiav ntawm qhov kev kho tiav tshiab. Kev sib txuas ua ke thiab kev lag luam ntawm Carlisle Bridge yog npaj siab kom dhau los tshaj 60 xyoo hauv kev pab cuam mus tas li.
