Mechanical interlockings , which prevented conflicting movements at rail junctions and crossings, were also introduced in the U.S. in the 1870s, after their initial development in ...

Developments in manufacturing technologies has led to changes to the design, manufacture and installation of rails, sleepers and the means of attachments. Cast iron rails, 4 feet (1.2 m) long, began to be used in the 1790s and by 1820, 15-foot-long (4.6 m) wrought iron rails were in use.
