PTC vs. Legacy Train Control

In this article, the author explores the history of railroad signal systems, which have evolved in response to rail safety challenges and needs. The year 1907 saw the highest number of passenger train fatalities and also marked the beginning of the discipline of railroad signal engineering. The author suggests that today’s Positive Train Control (PTC) should draw on signal and train control history and institutional knowledge to ensure that signal infrastructure remains safe, reliable and affordable.
