Dulmarka Guud ee R25-ka-qoditaanka ee R25 ee muabtaadda xarkaha
Uur-yada xarkaha ayaa guud ahaan ku habboon xoojinta taageerada ku saabsan tunellada macdanta, tunelada buundada, ilaalinta xawaaraha, iyo meelaha kale. Guud ahaan, godadka ushaxeed ee xargaha ayaa la qoday iyadoo la adeegsanayo daloolka ur-karka ah ee xijaabka, iyo wakiilada ku habboon (duubista budada ah) ayaa la dhigayaa. Kadib, aaladaha sida muraayadaha xarkaha ah ayaa loo isticmaalaa in lagu qoro usha xarkaha xarkaha xarkaha xarkaha xarkaha, walaaq oo u isticmaal aaladaha sida loo yaqaan 'xargaha' ' Usha xarkaha gacanta midig, oo sidoo kale loo yaqaan steat the the streesin steamed steamed steel, ayaa laga sameeyay sax (ama bidix) bir bir ah, oo leh xargaha joogtada ah iyo dherer buuxa oo lagu xidho nuts. Waxaa loo adeegsaday iyada oo lala kaashanayo xargaha xargaha xarkaha loo yaqaan 'cooska' nuts 'ee taageerada tunnel. Bolt waa wax soo saar beddelaad ah oo ah wax lagu beddelo oo ka mid ah dogor shiilan oo kacsan, oo leh wax qabad ka sarreeya.
