Ntau yam ntawm cov ntoo mos thiab cov ntoo tawv ntoo yog siv los ua kev sib raug zoo, ntoo qhib, jarrah thiab karri yog cov ntoo nyuaj, txawm tias nyuaj kom tau, tshwj xeeb tshaj yog los ntawm cov chaw ruaj khov. Qee kab siv softwoods, suav nrog Douglas fir; thaum lawv muaj qhov zoo ntawm kev lees txais kev kho mob yooj yim dua, lawv yooj yim dua rau hnav tab sis pheej yig dua, sib dua (thiab yog li yooj yim dua) thiab yooj yim dua. Softwood tau kho, nrog creosote yog cov tshuaj tiv thaiv tshaj plaws rau kev tsheb ciav hlau. Lwm cov tshuaj tiv thaiv siv suav nrog pentachlorophenol thiab chromated tooj liab arsenate. Qee lub sij hawm siv cov tshuaj tsis muaj tshuaj lom, xws li tooj liab azole lossis micronized tooj liab. Tshiab boron-raws li ntoo preserving technology yog ua hauj lwm los ntawm loj US railroads nyob rau hauv ib tug dual txoj kev kho mob nyob rau hauv thiaj li yuav mus cuag lub neej ntawm ntoo ties nyob rau hauv ntub dej. Qee cov ntoo (xws li sal, mora, jarrah lossis azobé) yog qhov ruaj khov txaus uas lawv tuaj yeem siv tsis kho.
Cov teeb meem nrog cov ntoo sib txuas muaj xws li rot, splitting, kab kab kab, phaj-txiav, los yog lub rooj zaum shuffle nyob rau hauv UK (abrasive puas tsuaj rau khi los ntawm lateral motion ntawm khi phaj) thiab spike-rub (qhov twg lub spike yog maj loosened. los ntawm kab). Ntoo khi tuaj yeem ntes hluav taws; raws li lawv muaj hnub nyoog lawv tsim cov kab nrib pleb uas tso cai rau lub teeb ci rau hauv tsev thiab yooj yim dua pib hluav taws.
Dhau li ntawm cov piv txwv tau hais los saum toj no, cov tshiab lossis qub ntoo qhib ntoo qhib muaj lwm qhov siv, xws li cov rooj tog zaum hauv tsev thiab qee qhov tsim vaj tsev.

Qhov tsuas txwv rau lawv siv yog kev xav.
Tsis tas li ntawd, tseem muaj ntau yam kev tsheb ciav hlau pw tsaug zog xws li pob zeb kev tsheb ciav hlau pw tsaug zog thiab steel sleepers. Txhawm rau hloov mus rau ntau hom kev tsheb ciav hlau, lawv txhua tus ua lub luag haujlwm tseem ceeb hauv kev thauj mus los ntawm kev tsheb ciav hlau.
