Long Life Cycle Switching for Railway Signal Systems: Design, Testing, and Selection
Author: Postek Engineering Team | Reading time: 10 minutes Introduction Railway signaling and control systems have some of the longest service life requirements in all of engineering — 20 to 30 years of continuous operation through temperature extremes, vibration, dust, moisture, cleaning chemicals, and in passenger-facing applications, deliberate abuse. Switches that work reliably in a lab at cycle 1,000 must work identically at cycle 1,000,000 after two decades in service. ...
