Isiteshi se-metro noma isiteshi esingaphansi komhlaba siyisiteshi sesitimela sohlelo lokuhamba olusheshayo, okuvame ukubizwa ngokuthi yi "metro" noma "subway".Isiteshi sihlinzeka abagibeli ngezindlela zokuthenga amathikithi, izitimela ezihamba ngamabhodi, nokususa uhlelo esimeni esiphuthumayo.E- United Kingdom, baziwa njengeziteshi zangaphansi komhlaba, ezisetshenziswa kakhulu ukubhekisa eLondon Underground. Indawo yesiteshi sikamasipala omkhulu kuhlelwe ngokucophelela ukuhlinzeka ukufinyelela okulula ezindaweni ezibalulekile zasemadolobheni ezifana nemigwaqo, izikhungo zezohwebo, izakhiwo ezinkulu nezinye izindawo zezokuthutha. Iziteshi eziningi zitholakala ngaphansi komhlaba, zingena / zingena ziholela phansi noma ezingeni lomgwaqo. Kwenqwaba esiteshini ngokuvamile ibekwe ngaphansi komhlaba agodliwe ukuze umphakathi thoroughfares noma amapaki.Ukubeka isiteshi ngaphansi komhlaba kunciphisa indawo engaphandle ehlala isiteshi, kuvumela izimoto nabahamba ngezinyawo ukuthi baqhubeke nokusebenzisa indawo ephansi ngendlela efanayo nangaphambi kokwakhiwa kwesiteshi.Lokhu kubalulekile ikakhulu lapho esiteshini ukhonza Isidlulisilwazi emagcekeni ezisemadolobheni, lapho ezingeni eliphansi izikhala kakade kakhulu esetshenzisiwe. Ezingeni lomgwaqo uphawu lwenkampani kamasipala luphawula ukungena / ukuphuma kwesiteshi.Imvamisa, izimpawu zikhombisa igama lesiteshi futhi zichaza izakhiwo zesiteshi nohlelo olusisebenzelayo.Imvamisa kuba neminyango eminingana yesiteshi esisodwa, okusindisa abahamba ngezinyawo ekudingweni ukuwela umgwaqo nokunciphisa ukuminyana. Isiteshi se-metro sihlinzeka ngokuthengiswa kwamathikithi nezinhlelo zokuqinisekisa ithikithi.Isiteshi sihlukaniswe indawo engakhokhelwa exhunywe emgwaqweni, nendawo ekhokhelwayo exhunywe kuzingxenyekazi zezitimela.
