Before the invention of railroads, city neighborhoods were often characterized by a mix of different people because communities were primarily localized and accessible by foot or horse-drawn vehicles. This proximity encouraged social interaction among diverse groups, as various trades, services, and residences coexisted closely. Additionally, without the ease of transportation that railroads provided, individuals tended to live near their workplaces, leading to a more integrated and multicultural urban environment.
