Izici zabo zifaka:
Amandla aphezulu: Izitimela zivame ukwenziwa ngensimbi esezingeni eliphakeme, enamandla aphezulu nobulukhuni futhi zingamelana nezitimela ezisindayo kanye nomthelela oxhumene nezigaba ezinde ngokusebenzisa ukuqina nokuphepha okuphelele umugqa wesitimela.
Amazinga wojantshizivame ukusethwa yinhlangano yamazwe omhlaba ukuze zilinganise (i-ISO) kanye namazinga embonini yesitimela yezwe ngalinye. Nazi ezinye izindinganiso ezijwayelekile zesitimela:
I-GB Standard Steel Rail, u-Arema Standard Steel Rail, i-ASTM Standard Steel Rail, u-En Standary Steel Rail, i-BS Standard Steel Rail, i-Din Standard Steel Rail, njengojantshi wensimbi eyi-1085.
