A signal indication

Winter weather often brings challenging driving conditions, and with that comes the inevitable opportunity for mishap. And so was the outcome of a recent winter driving incident at the Snoqualmie Parkway railway crossing.  The incident did not involve a train or engine, and there were no serious injuries.  However, the multiple vehicle accident resulted in the loss of a mast and signals in the center median when a deflected vehicle struck the mast, broke it off at the base, and the resulting impact with the local terrain damaged nearly every component.  Fortunately, no one was seriously injured, and the vehicle owner was appropriately insured.

The Northwest Railway Museum is responsible for five railroad crossing signal systems. With limited project work and just occasional component failures, the Museum only rarely purchases replacement parts.  So it came as quite a surprise to learn how much consolidation and change in the railroad signal industry has taken place in the last few years: now many signal components are supplied by Siemens Rail Automation, and nearly everything is made to order. So instead of purchasing parts “off the shelf,” a new assembly was ordered.  About six weeks later, it arrived on a truck ready for installation.
