What is the relationship between railroads and cities?

Railroads have historically played a crucial role in the growth and development of cities by facilitating transportation, commerce, and migration. They enabled the efficient movement of goods and people, contributing to urbanization and the expansion of industries. As railroads connected rural areas to urban centers, they spurred economic opportunities, leading to increased population density and the emergence of new neighborhoods and infrastructure. Ultimately, the presence of railroads often determined the location and success of cities.
