Abstract
A railroad rail produced by rolling a substantially round bloom, together with a process and system for manufacturing the same. The round bloom may be produced by continuous casting methods. The bloom is initially rolled into a substantially rectangular shape and then into a rail. The rolling process may be continuous and in-line to allow for the production of very long seamless rails.

- a first set of rollers for rolling the billet into a substantially rectangular cross-section;
- a second set of rollers for rolling the rectangular cross-section into a rail;
- and means for transporting the billet from the caster to the first rollers.
