Life Along the Tracks: The Rise of Railroad Settlements
The 19th and early 20th centuries experienced an extraordinary growth of railway networks throughout continents. To facilitate this development, railroad business established settlements along these routes. These were typically hastily planned and built, intended to be useful and functional instead of picturesque. They functioned as functional hubs, housing maintenance backyards, repair shops, and marshalling areas. The population of these settlements was mainly composed of railroad employees-- track layers, mechanics, engineers, and their families-- together with merchants and company who dealt with their needs.
Life in railroad settlements provided an unique set of challenges and situations. Real estate was typically standard and company-owned, often situated in close proximity to rail yards and commercial activities. Access to tidy water and sanitation could be restricted, and ecological guidelines were frequently non-existent or badly enforced throughout the period of their rapid growth. The main market, railroading, itself was naturally dangerous, exposing workers to a variety of possibly carcinogenic substances. These settlements, therefore, became microcosms of early commercial life, embodying both its chances and its fundamental threats.
Emerging Evidence: The Stomach Cancer Connection
Over the previous couple of decades, epidemiological studies have actually begun to shed light on a troubling pattern: people with a history of living or operating in railroad-related environments display a statistically significant increased danger of developing stomach cancer.
