Why the railroad spike was replaced by a spring clip
In short: For generations, massive steel spikes held tracks in place. This video explains why modern railways transitioned to spring clips to handle the demands of high-speed travel and heavy loads.
While railroad spikes were the standard for years, modern rail infrastructure requires a more sophisticated fastening system. The shift to heavy-duty spring clips was driven by the need for a solution that can manage extreme vibrations and significant temperature fluctuations.
Modern tracks often feature continuously welded rails and concrete sleepers. Unlike traditional spikes, spring clips provide the necessary flexibility and strength to keep trains safely on track under heavy loads, ensuring stability across diverse environments.
