The answer is the Staggers Rail Act of 1980.
The Staggers Rail Act of 1980 significantly deregulated the American railroad industry. It allowed railroads to set their own rates and enter into contracts with shippers without extensive government oversight. This act enabled railroads to compete more effectively, improve efficiency, and become profitable again.
The Interstate Commerce Act of 1887 was the first federal law to regulate the railroads, primarily to ensure fair rates and to eliminate rate discrimination. However, it did not give railroads the ability to compete with one another; rather, it imposed regulations to control their operations.
The Hepburn Act of 1906 strengthened federal regulation of railroads by giving the Interstate Commerce Commission (ICC) the power to set maximum railroad rates and extend its jurisdiction. This act increased regulation rather than promoting competition.
The Transportation Act of 1920 aimed to address the financial difficulties of railroads post-World War I by providing federal control and financial assistance. It did not focus on deregulation or enhancing competition among railroads.
In conclusion, the Staggers Rail Act of 1980 is the legislation that allowed railroads to compete with one another again, leading to increased profitability.
