Railways Act 1921 (UK)

The Railways Act 1921 was a UK law that reorganized the country's railway companies into four large groups, called "groups" or "supergroups," to improve efficiency and coordination after World War I. It aimed to reduce competition, fix financial issues, and modernize the rail network. The Act effectively consolidated over 100 separate railway companies into manageable units, ensuring better consistency, safety, and service for passengers and freight. It laid the foundation for future national railway development and streamlined operations across the country.
