How Steel Rails Are Made | AGICO Rail

Sep 29, 2017 · As we know, the steel billet through rolling, cooling, and straightening can be made to the rails. During the process, the vital part is rolling. There are two methods to rolling: groove rolling and universal rolling. Groove rolling is simpler than the universal rolling. The metal deformation is steady.

How to Railbank | Rails-to-Trails Conservancy

How to Railbank. Railbanking takes place during a rail corridor abandonment process. Official negotiations with a railroad begin after the railroad submits an initial notification to abandon a line (similar to a letter of intent to abandon) to the Surface Transportation Board (STB). Negotiations end with either railbanking or line abandonment.

Rail stressing - Wikipedia

Stressing is a rail engineering process. It is used to prevent heat and cold tension after installation of continuous welded rail (CWR). Environmental heat causes CWR to expand and therefore can cause the fixed track to buckle.Environmental cold can lead to the contraction of the fixed railway track causing brittleness and cracks.

Steel for many purposes. Rail steel.

Rail steel is designed to wear away very slowly to avoid surface cracking. The rails don’t wear evenly and this often produces an incorrect rail to wheel geometry. This uneven profile accelerates the wearing process. The problem is overcome by regular light grinding to restore the optimum rail profile.
