Njengoko sihamba sisuka kwenye indawo siye kwenye, sihlala sithatha lula uthungelwano oluntsonkothileyo lweziseko zophuhliso zikaloliwe oluvumela ukusebenza kakuhle nangokufanelekileyo koololiwe. Embindini wesi siseko kukho iireli zentsimbi, ezenza icandelo eliphambili leendlela zikaloliwe. Phakathi kweentlobo ngeentlobo zeereli zentsimbi ezikhoyo, ezo zinamathela kumgangatho we-BS zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokuthembeka kweenkqubo zikaloliwe.
Isitimela sentsimbi esisemgangathweni se-BS, eyaziwa ngokuba yiBritish Standard Rails, iyilwe kwaye yenziwa ngokweemfuno ezibekwe yiBritish Standards Institution (BSI). Ezi rails zenzelwe ukuhlangabezana neemfuno ezingqongqo zomgangatho kunye nokusebenza, nto leyo eyenza ukuba zibe lukhetho olubalulekileyo kwiiprojekthi zokwakha nokugcina oololiwe. Ukunamathela kumgangatho we-BS kuthetha ukuzibophelela ekugqweseni, ukuqina, kunye nokuhambelana ekuvelisweni koololiwe bentsimbi, ekugqibeleni negalelo ekusebenzeni kakuhle nasekukhuselekeni kwemisebenzi yoololiwe.
Enye yezona nzuzo ziphambili zeereli zentsimbi ezisemgangathweni ze-BS kukuqina kwazo okuphezulu kunye nokuqina kwazo. Ezi reli zakhiwe kusetyenziswa izixhobo zentsimbi ezikumgangatho ophezulu kwaye zivavanywa ngokungqongqo ukuqinisekisa ukuba ziyakwazi ukumelana nemithwalo enzima, iimeko zemozulu ezigqithisileyo, kunye nokuguguleka rhoqo. Ngenxa yoko, zibonelela ngokumelana okugqwesileyo nokuguquguquka, ukuqhekeka, kunye nokugqwala, ngaloo ndlela zandisa ubomi bemizila kaloliwe kwaye zinciphisa isidingo sokutshintshwa okanye ukulungiswa rhoqo. Olu kuqina lubalulekile ekugcineni ukuthembeka kweziseko zophuhliso zikaloliwe kunye nokuthintela ukuphazamiseka kweenkonzo zoololiwe.

Ukongeza kulwakhiwo lwabo oluqinileyo,iireli zentsimbizenzelwe ukuhlangabezana nobunzima obuchanekileyo kunye nobunzima bejometri. Eli nqanaba lokuchaneka libalulekile ekuqinisekiseni ukuhamba okuthe tye nokuzinzileyo koololiwe ecaleni kwendlela. Ngokulandela imigaqo ye-BS standard, ezi reli zenziwe ngeeprofayili ezinqamlezileyo, ukuthe tye, kunye nokulungelelaniswa, ezibalulekileyo ekunciphiseni ukungalungelelani kwendlela kunye nokugcina unxibelelwano olufanelekileyo phakathi kwamavili oololiwe kunye neereli. Ijometri echanekileyo yeereli zentsimbi ze-BS standard inegalelo kukhuseleko kunye nentuthuzelo yokuhamba ngololiwe, ukunciphisa umngcipheko wokuqhekeka komzila kunye nokuphucula ukusebenza kakuhle kwenethiwekhi yololiwe.
Ngaphezu koko, ukunamathela kumgangatho we-BS kuqinisekisa ukuba iireli zentsimbi zilandelwa ngamanyathelo olawulo lomgangatho kuyo yonke inkqubo yokuvelisa. Ukususela ekukhetheni izinto eziluhlaza ukuya ekuhlolweni kokugqibela kweereli ezigqityiweyo, ukunamathela ngokungqongqo kumgangatho kuqinisekisa ukuba iireli ziyahlangabezana neempawu zoomatshini ezifunekayo, ukwakheka kweekhemikhali, kunye neempawu zokusebenza. Eli nqanaba lolawulo lomgangatho libalulekile ekufakeni ukuzithemba ekuthembekeni nasekusebenzeni kweereli zentsimbi ezisemgangathweni we-BS, kubonelela abaqhubi boololiwe kunye nabaphathi beziseko zophuhliso ngesiqinisekiso sokuba iireli ziya kuhlangabezana neemfuno zomsebenzi woololiwe onzima rhoqo.
Ukubaluleka kwee-BS standard steel rails kudlulela ngaphaya kweempawu zazo zomzimba, njengoko zikwadlala indima ebalulekileyo ekukhuthazeni ukusebenzisana kunye nokuhambelana kwishishini lezoololiwe lehlabathi. Ngokunamathela kwimigangatho eyaziwayo nehlonitshwayo efana ne-BS standard, iiprojekthi zeziseko zophuhliso zikaloliwe zinokuzuza ngokuhambelana noluhlu olubanzi lwempahla eqengqelekayo, iinkqubo zokubonisa, kunye nezixhobo zokulungisa ezenzelwe ukunxibelelana ngokungenamthungo nee-rails ezihlangabezana nemigangatho efanayo. Oku kusebenza kunye kwenza kube lula iinkqubo zokuthengwa, ukufakwa, kunye nokugcinwa kweziseko zophuhliso zikaloliwe, ekugqibeleni kukhokelele ekongeni iindleko kunye nokusebenza kakuhle kwabaqhubi boololiwe kunye nabasemagunyeni.
Ukuqukumbela, ukusetyenziswa kwe-BSUloliwe oqhelekileyoibaluleke kakhulu kuphuhliso, ulwandiso, kunye nokugcinwa kweziseko zophuhliso zoololiwe banamhlanje. Ezi ziporo zimele imigaqo yomgangatho, ukuqina, ukuchaneka, kunye nokusebenzisana, konke oku kubalulekile ekuqinisekiseni ukusebenza ngokukhuselekileyo nangokufanelekileyo kothungelwano loololiwe. Njengoko imfuno yeenkqubo zoololiwe ezithembekileyo nezisebenza kakuhle iqhubeka ikhula, indima yeeroli zentsimbi ezisemgangathweni ze-BS ekubumbeni ikamva lokuthuthwa koololiwe ayinakugqithiswa. Ngokugcina imigangatho ebekwe yiBritish Standards Institution, ishishini loololiwe lingaqhubeka nokuthembela kumandla aqinisekisiweyo eeroli zentsimbi ezisemgangathweni ze-BS ukuxhasa ukuhamba kwabantu kunye neempahla ngokuzithemba nangokuthembekileyo.
