Ezinye izithombe zamarayili ahlelwe ngobunono

Iyini isitimela sensimbi?

Isitimela sensimbis izingxenye eziyinhloko zamathrekhi wesitimela. Umsebenzi wabo uwukuqondisa amasondo e-rolling stock, ethwala ingcindezi enkulu evezwa amasondo futhi ayidlulisele kwabalalayo.Ujantshis kumele inikeze indawo eginqikayo eqhubekayo, ebushelelezi, futhi imelana kancane yamasondo. Kojantshi abafakwe ugesi noma ezigabeni ezizenzakalelayo zamabhulokhi, ojantshi basebenza njengamasekhethi ethrekhi.

Izithombe zezinsimbi zensimbi kwezokuthutha

Izinzuzo zokusebenzisa izinsimbi zensimbi

Ukusebenza okuyingqayizivele kwesteel rails isiqus kusuka ezintweni zabo eziyingqayizivele kanye nobuciko. Igoqwe kusuka kunsimbi yekhwalithi ephezulu ye-carbon steel noma i-low-alloy steel, ama-rails abhekana nezinqubo zokwelashwa kokushisa okufana nokucisha nokushisa, okuholela esakhiweni esiyinhlanganisela esinobuso obuqinile, obungagugi kanye nengaphakathi eliqine ngendlela emangalisayo. Ukuqina kobuso bungafinyelela ngaphezu kwe-HB300, kuyenze ikwazi ukumelana nokucindezela okungaguquki kanye nokugedla kwamasondo, kuyilapho ukuqina komgogodla kunciphisa umthelela wokubhuleka nokuqalisa izitimela, kuvimbele ukuphuka okungama-brittle. Ngaphezu kwalokho, idizayini ye-cross-sectional kajantshi ithobela izimiso zobukhenika. IIsigaba esimise okwe-Iiqinisekisa amandla anele okuthwala umthwalo ngenkathi inciphisa isisindo sayo, ifinyelela ukulingana okuphelele phakathi kwamandla okuthwala umthwalo kanye nokusebenza kahle kwezomnotho.

Amanye ama-rails ensimbi ahlelwe ngokuphambana

Izitimela zekhwalithi ephezulu ziletha izinzuzo eziningi ohlelweni lwesitimela

Okokuqala, banikeza impilo yesevisi ende ngokuhlukile.Izinsimbi zekhwalithi ephezuluzingaphezu kuka-30% ukumelana nokuguga kunensimbi evamile. Ngaphansi kwezimo ezivamile zokusebenza, zingamelana nenani levolumu yokuthutha elingaphezu kwamathani ayizigidi eziyizinkulungwane ezingu-1, kunciphisa kakhulu imvamisa yokushintshwa kwethrekhi.

Okwesibili, ukuphepha kokusebenza. Inqubo enembile yokugingqika iqinisekisa indawo kajantshi ebushelelezi, inciphisa ukudlidliza nomsindo ngesikhathi sokusebenza kwesitimela futhi inciphise ubungozi bokuqhekeka okubangelwa ukukhathala kukaloliwe.

Ekugcineni, banikeza izindleko ezincishisiwe zokunakekela. Ojantshi bekhwalithi ephezulu bamelana nokugqwala futhi bazinzile, benciphisa umsebenzi wokugaya nokulungiswa kwansuku zonke, okwenza imisebenzi yezitimela isebenze kahle.

Isicelo of rails ekuphileni kwansuku zonke

Ngokombono wohlelo lokusebenza, ama-rails ensimbi atholakala kuzo zonke izinhlobo zeuhlelo lwesitimelas.
1. Kojantshi wesitimela esinesivinini esikhulu, ubuchwepheshe bezitimela ezingenamthungo bunweba ingxenye ngayinye kajantshi ibe ngamakhulu amamitha, isuse ukunyakazisa kwezikhala zamathrekhi futhi ivumele izitimela zihambe kahle ngesivinini esingaphezu kwamakhilomitha angama-300 ngehora.
2. Ojantshi abathwala kanzima bathembele kuboama-rails ensimbi aphezulu, ezithwala izitimela zezimpahla ezingamathani angu-10 000 futhi zidlala indima ebalulekile ekuthuthweni kwempahla ngobuningi njengamalahle namaminerali.
3. Emizileni engaphansi komhlaba yasemadolobheni kanye nezinhlelo zikaloliwe ezincane, ukuxhunyaniswa okunembayo kwamareyili nezinsimbi zokubopha amathrekhi kuqinisekisa ukuphepha nokugcina isikhathi phakathi nokusebenza kwezitimela eziminyene kakhulu.
4. Ngisho nasezitshalweni zezimboni nasemachwebeni, ama-rails ensimbi aklanywe ngokukhethekile akha imithambo yezokuthutha endaweni, enze kube lula ukushintshwa kwempahla.

Ukuvela kwama-rails

Nakuba kuthulile, izinsimbi zensimbi zifakazela ukuthuthukiswa okuqhubekayo kwamanethiwekhi ezokuthutha. Kusukela ekunembeni kobukhulu bezinga lemilimitha ukuya kumthamo wokulayisha owedlula amathani angu-10,000, kusukela ekuhambeni okukahle kwasemadolobheni kuya ekuhleleni okushelelayo kwe-intercontinental, le migoqo yensimbi emide ingaphezu nje kwamathrekhi abonakalayo; "yimithambo yegazi yensimbi" exhuma izifunda futhi iqhubekisele phambili intuthuko. Ngokuzayo, ngokuthuthuka kobuchwepheshe bezinto ezibonakalayo, ama-rails ensimbi azothuthukela ekungagugini okukhulu, ukumelana nokugqwala, nokwakhiwa okungasindi, eqhubeka nokusekela ukuphishekela komuntu isivinini nokusebenza kahle okungaphezi.
