Why did the railroads initially divide the United states into four zones?

Answer 1

The railroads initially divided the United States into four zones to facilitate more efficient management and operations of the expanding rail network. Each zone allowed for better coordination of train schedules, maintenance, and logistics, which were essential for handling the growing volume of freight and passenger traffic. This division also helped standardize practices and regulations across different regions, ultimately contributing to the seamless connectivity of the national rail system. Additionally, it enabled companies to compete effectively while maintaining safety and reliability across their services.
