Steel rails are the load bearing and guiding elements in a railway or tramway track. Individual fragments are bolted or welded together forming a continuous line that supports railcar wheels. The cross section of the rail segment, or the profile, has varied over time and by application area.
Two sets of modern rail elements in common use include train and tram. The train rail profile is an asymmetrical I-beam with a wide flat-bottom that fits on the railroad track. Wheels rest on top of the rail, with wheel flanges extending downwards on the insides of the rails. A grooved head characterizes tram rail segments. In this configuration, the wheel flange sits within the groove on the rail head.
