Njengoko sihamba sisuka kwenye indawo sisiya kwenye, sihlala sithatha lula uthungelwano oluntsonkothileyo lweziseko zoncedo zikaloliwe ezenza ukuba oololiwe basebenze ngokutyibilikayo nangokufanelekileyo.Embindini wesi siseko kukho iintsimbi zentsimbi, ezenza icandelo elisisiseko lemizila kaloliwe.Phakathi kweentlobo ezahlukeneyo zeentsimbi zentsimbi ezikhoyo, ezo zibambelela kumgangatho we-BS zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokuthembeka kweenkqubo zikaloliwe.
BS isiporo sentsimbi eqhelekileyo, eyaziwa ngokuba yiBritish Standard Rails, iyilwe kwaye yenziwe ngokuhambelana nemigaqo ebekwe yiBritish Standards Institute (BSI).Ezi ziporo zenzelwe ukuhlangabezana neemfuno ezingqongqo zomgangatho kunye neemfuneko zokusebenza, nto leyo ezenza zibe lukhetho olubalulekileyo kulwakhiwo lukaloliwe kunye neeprojekthi zolondolozo.Ukuthotyelwa komgangatho we-BS kubonisa ukuzibophelela ekugqweseni, ukuqina, kunye nokungaguquguquki ekuvelisweni kweentsimbi zentsimbi, ekugqibeleni kube negalelo ekusebenzeni kakuhle kunye nokhuseleko lwemisebenzi kaloliwe.
Enye yeenzuzo eziphambili ze-BS iintsimbi zentsimbi ezisemgangathweni ngamandla azo aphezulu kunye nokuqina.Ezi reyile zakhiwe kusetyenziswa izixhobo zentsimbi ezikumgangatho ophezulu kwaye zivavanywa ngokuqatha ukuqinisekisa ukuba zikwazi ukumelana nemithwalo enzima, iimeko zemozulu ezimandundu, kunye nokugqojozwa okuthe rhoqo.Ngenxa yoko, banikezela ngokuxhathisa okukhethekileyo kuguquko, ukuqhekeka, kunye nokudleka, ngaloo ndlela bandisa ubomi bemizila kaloliwe kunye nokunciphisa imfuno yokutshintshwa rhoqo okanye ukulungiswa.Oku komelela kubalulekile ekugcineni imfezeko yeziseko zophuhliso zikaloliwe kunye nokuthintela ukuphazamiseka kwiinkonzo zoqeqesho.

Ukongeza kulwakhiwo lwabo oluqinileyo,iintsimbi zentsimbiziyilelwe ukuhlangabezana nobukhulu obuchanekileyo kunye nokunyamezelana kwejometri.Eli nqanaba lokuchaneka libalulekile ekuqinisekiseni intshukumo egudileyo nezinzileyo yoololiwe ecaleni kwemizila.Ngokuthobela imigangatho ye-BS, ezi mzila zenziwa ngeeprofayili ezinqamlezayo, ukuthe tye, kunye nokulungelelaniswa, eziyimfuneko ekunciphiseni izitenxo zomzila kunye nokugcina unxibelelwano olufanelekileyo phakathi kwamavili oololiwe kunye neereyile.Ijiyometri echanekileyo ye-BS yentsimbi yentsimbi esemgangathweni inegalelo kukhuseleko lulonke kunye nokukhululeka kohambo lukaloliwe, ukunciphisa umngcipheko wokuchasa kunye nokuphucula ukusebenza kakuhle kothungelwano lukaloliwe.
Ngaphezu koko, ukuthotyelwa komgangatho we-BS kuqinisekisa ukuba iileyili zentsimbi zithatha amanyathelo afanelekileyo okulawula umgangatho kuyo yonke inkqubo yokuvelisa.Ukususela ekukhethweni kwezinto eziluhlaza ukuya ekuhlolweni kokugqibela kweereyili ezigqityiweyo, ukuthotyelwa ngokungqongqo kwimigangatho yokuqinisekisa ukuba iileyili zihlangabezana neempawu ezifunekayo zomatshini, ukubunjwa kweekhemikhali, kunye neempawu zokusebenza.Eli nqanaba lolawulo lomgangatho liyimfuneko ekufakeni ukuzithemba ekuthembekeni nasekusebenzeni kweentsimbi zensimbi eziqhelekileyo ze-BS, ukubonelela abaqhubi bakaloliwe kunye nabaphathi beziseko zoncedo ngesiqinisekiso sokuba iileyili ziya kuhlala zihlangabezana neemfuno zemisebenzi kaloliwe enzima.
Ukubaluleka komgangatho we-BS iintsimbi zentsimbi kudlulela ngaphaya kweempawu zazo ezibonakalayo, njengoko zikwadlala indima ebalulekileyo ekukhuthazeni ukusebenzisana kunye nokubekwa emgangathweni kushishino lukaloliwe lwehlabathi.Ngokuthobela umgangatho owamkelwayo nohlonitshwayo ofana nomgangatho we-BS, iiprojekthi zeziseko ezingundoqo zikaloliwe zinokuxhamla ekusebenzisaneni noluhlu olubanzi lwesitokhwe esiqengqelekayo, iinkqubo zokubonisa, kunye nezixhobo zogcino eziyilelwe ukuba zijongane ngokungenamthungo kunye neereyile ezihlangabezana nomgangatho ofanayo.Oku kusebenzisana kwenza lula ukuthengwa, ukufakwa, kunye nokugcinwa kweenkqubo zikaloliwe, ekugqibeleni kukhokelele ekongiweni kweendleko nokusebenza ngokukuko kubasebenzi bakaloliwe nabasemagunyeni.
Ekugqibeleni, ukusetyenziswa kwe-BSUloliwe oMgangathoubalulekile kuphuhliso, ukwandiswa, nokugcinwa kweziseko zoncedo zikaloliwe zanamhlanje.Ezi ziporo zibandakanya imigaqo yomgangatho, ukuqina, ukuchaneka, kunye nokusebenzisana, zonke ezo zinto ziyimfuneko ekuqinisekiseni ukusebenza ngokukhuselekileyo nangokufanelekileyo kothungelwano lukaloliwe.Njengoko imfuno yeenkqubo zikaloliwe ezithembekileyo nezikumgangatho ophezulu ziqhubeka nokukhula, indima ye-BS yentsimbi yentsimbi esemgangathweni ekubumbeni ikamva lothutho lukaloliwe ayinakuba ngaphezulu.Ngokuphakamisa imigangatho ebekwe liZiko leMigangatho yaseBritani, ishishini likaloliwe linokuqhubeka lithembela kwisakhono esiqinisekisiweyo se-BS yentsimbi yentsimbi esemgangathweni ukuxhasa ukuhamba kwabantu kunye nempahla ngokuzithemba nokuthembeka.
