Njengoba sihamba sisuka kwenye indawo siye kwesinye, sivame ukuthatha kalula inethiwekhi eyinkimbinkimbi yengqalasizinda yesitimela eyenza ukusebenza okubushelelezi nokusebenzayo kwezitimela. Enhliziyweni yalesi sigaba sezingqalasizinda kuwumjaja wensimbi, owakha ingxenye eyisisekelo yamathrekhi wesitimela. Phakathi kwezinhlobo ezahlukahlukene zojantshi bezinsimbi ezitholakalayo, labo abanamathela ezindabeni ze-BS badlala indima ebalulekile ekuqinisekiseni ukuphepha kanye nokwethenjwa kwezinhlelo zesitimela.
I-BS Standard Steel Rail, eyaziwa nangokuthi ujantshi ojwayelekile waseBrithani, yakhelwe futhi yenziwe ngokuya ngokuchazwa kwezikhungo zamazinga waseBrithani (BSI). Lezi zitimela zinenjinizo ukuze zihlangabezane nekhwalithi eqinile nezidingo zokusebenza, zibenze ukuba kube yisinqumo esibalulekile sokwakhiwa kwesitimela namaphrojekthi wokulungisa. Ukubambelela eziteshini ze-BS kusho ukuzibophezela kokuhle, ukuqina, kanye nokungaguquguquki ekukhiqizweni kwezitimela zensimbi, kufaka ekugcineni ekusebenzeni kahle nasekufezeni ukuphepha kwesitimela.
Enye yezinzuzo ezisemqoka zemizila yensimbi ejwayelekile yamandla abo aphezulu nokuqina. Lezi zitimela zakhiwa zisebenzisa izinto ezisezingeni eliphakeme zensimbi futhi zihlolwe kanzima ukuze ziqinisekise amandla azo okubekezelela imithwalo esindayo, isimo sezulu esibi kakhulu, kanye nokugqoka njalo. Ngenxa yalokhu, bavumelanisa ukumelana okuhlukile ekuguqukeni, ukuqhekeka, kanye nokugqwala, ngaleyo ndlela kunwebe isikhathi sokuphila kwezitimela futhi kunciphise isidingo sokufakwa esikhundleni noma ukulungisa njalo. Lokhu kuqina kubalulekile ukuze kugcinwe ubuqotho bengqalasizinda yesitimela nokuvimbela ukuphazamiseka kwezinsizakalo zokuqeqesha.

Ngaphezu kokwakhiwa kwabo okuqinile,Izitimela zensimbiyakhelwe ukufeza ukubekezelelwa okunembile okunezinkomo kanye nejometri. Leli zinga lokunemba libalulekile ekuqinisekiseni ukuhamba okubushelelezi nokuzinzile kwezitimela eceleni kwamathrekhi. Ngokulandela imininingwane ejwayelekile ye-BS, le mizila yenziwa ngamaphrofayli angaguquki wesigaba, ukuqonda, kanye nokuqondanisa, okubalulekile ukuze kunciphise ukulandela umkhondo nokulandela amasondo ezitimela kanye nojantshi. I-geometry eqondile yemijaho yensimbi ejwayelekile ye-BS inomthelela ekuphepheni okuphelele kanye nenduduzo yokuhamba kwesitimela, ukunciphisa ubungozi bezikhathi zokuvunyelwa kanye nokwenza ngcono ukusebenza kwenethiwekhi yesitimela.
Ngaphezu kwalokho, ukunamathela ezijwayelekile ze-BS kuqinisekisa ukuthi ujantshi wensimbi ubhekene nezindlela zokulawula ezisezingeni elifanele kuyo yonke inqubo yokukhiqiza. Ukusuka ekukhetheni kwezinto ezivuthiwe ekuhlolweni kokugcina kojantshi abaqediwe, ukubambelela okuqinile kwiZinga eliqinisekisa ukuthi ojantshi bahlangabezana nezakhiwo ezidingekayo zemishini, ukwakheka kwamakhemikhali, kanye nezimpawu zokusebenza. Leli zinga lokulawulwa kwekhwalithi libalulekile ukuze ligxilise ukuzethemba ekuthembekeni nasekusebenzeni kwezitimela ezijwayelekile ze-BS, ukuhlinzeka abaphathi bezitimela kanye neziphathimandla zengqalasizinda ezihlangabezana nezidingo ze-Heavy-Full Trailetions imisebenzi.
Ukubaluleka kwezitimela zensimbi ezijwayelekile ze-BS zifinyelela ngaphezu kwezimfanelo zazo ezingokomzimba, ngoba futhi zidlala indima ebalulekile ekuthuthukiseni ukusebenzisana kanye nokwenza okujwayelekile embonini yesitimela yomhlaba. Ngokunamathela ezilinganisweni ezaziwayo futhi ezihlonishwayo ezifana ne-BS Standard, amaphrojekthi wengqalasizinda yezitimela angahlomula ekuvumelaniseni okuhlukahlukene kwesitoko, ukusayina, amasistimu wokugcina, kanye nemishini yokulungisa eyenzelwe ukusenza ngezinga elifanayo. Lokhu ukusebenzisana kube lula izinqubo zokuthengwa kwempahla, ukufakwa, kanye nezinqubo zokulungisa izingqalasizinda zesitimela, ekugcineni kuholele emalini yokonga kanye nokusebenza kokusebenza kwabasebenza izitimela neziphathimandla.
Ekuphetheni, ukusetshenziswa kwama-BSIsitimela EsijwayelekileKubaluleke kakhulu ngentuthuko, ukunwetshwa, kanye nokugcinwa kwengqalasizinda yesitimela yesimanje. Lezi zijantshi zihlanganisa imigomo yekhwalithi, ukuqina, ukunemba, kanye nokusebenzisana, konke okubalulekile ekuqinisekiseni ukusebenza okuphephile nokusebenzayo kwamanethiwekhi wesitimela. Njengoba ukufunwa kwezinhlelo zesitimela ezinokwethenjelwa nokwenziwa ngcono kuyaqhubeka kukhula, indima ye-BS Standard Rail rail ngokubumba ikusasa lokuhamba kwezitimela alinakwenga. Ngokusekela izindinganiso ezibekwe yisikhungo sezindinganiso zeBrithani, imboni yesitimela ingaqhubeka nokuthembela kumakhono afakazelwe we-BS Standard Steel Rail ukusekela ukunyakaza kwabantu kanye nokwethenjwa.
