American standard,which also known as AREMA A.S.C.E, refers the standard used to the American railway. American standard covers many types of railway track, such as hot-rolled rail, heat treated rail and rail for switch, all these steel rail can be applied in the mph 200 or 350 passenger railway, mph 160 or 200 railway, etc. common A.S.C.E standard steel rail include ASCE25, ASCE30, ASCE40, ASCE60, ASCE75, ASCE85, 115Re, 132Re, 136Re etc.
