The railroad switch, a seemingly simple yet ingenious mechanism, has played a vital role in rail transportation since the inception of railroads. By enabling trains to change tracks, switches have transformed rail shipping, enhancing their efficiency, safety, and flexibility. As we celebrate National Inventor’s Day, we honor the brilliant minds whose innovations have shaped the modern railroad switch. Below, we delve into the contributions of several key inventors to understand their impact on rail shipping today.
John Curr (1787)
Invention: Early railway switch mechanism
John Curr, an English engineer, is credited with inventing one of the earliest versions of the railway switch in 1787.
