Iarnród cruach, ar a dtugtar againn freisin ráillí, rianta, is gné thábhachtach den chóras iarnróid. Úsáidtear an t-iarnród cruach le hailt iarnróid agus dúntóirí iarnróid cosúil le gearrthóg iarnróid, pláta ceangail railraod, casadh amach chun an traein a reáchtáil go tapa agus go seasta gan stiúradh.
Cad iad na cineálacha éagsúla ráillí?
Heavy rail, light rail, and crane rail are classifications of steel tracks, differentiated by weight, strength, and use: Light rails (under 30kg/m) are for temporary/light-duty use (mines, factories); Heavy rails (>30kg/m) do phríomh-iarnróid; agus tá ráillí Crane (cosúil le sraith QU) speisialaithe, rianta láidre do chraenacha, le próifílí beachta agus friotaíocht ard-chaitheamh le haghaidh ualaí tionsclaíocha troma.
