Rail section dimensions mainly contain the rail height, the width of the base, the width of the head, the web thickness, the depth of head, the depth of the base, nominal weight per yard or meter. Railroad rail dimensions provide a method of identifying types of most rails. The charts below list common railroad track dimensions such as ASCE Rail, 115Re Rail, UIC60 Rail, DIN Rail, other Crane rail, and more. Some of the mill marks on rails are shown too.
