A 1.25 km segment of a heavy haul coal line was instrumented with Rail Stress Monitors (RSM) [1–7] and monitored throughout a winter-summer swing in ambient conditions. The track segment included a reverse curve spanning elevated, at-grade, and tunnel conditions that transitioned to a turnout. Natural events along with track maintenance activity punctuated the seasonal shifts in Stress Free Temperature (SFT).
