Zambiri za Rail Steel
Chitsulo cha njanji, chomwe chimadziwika kuti chitsulo chanjanji, ndichitsulo chapadera muzitsulo zazitsulo zomwe zimagwiritsidwa ntchito kwambiri pamanjanji anjanji. Sitimayi imanyamula kulemera kwake komanso mphamvu ya sitimayi. Pamwamba pake amavala, ndipo mutu umakhudzidwa. Sitimayi imakhudzidwanso ndi kupsinjika kwakukulu kopindika. Makina osindikizira ovuta komanso ntchito zanthawi yayitali zimabweretsa kuwonongeka kwa njanji.
