This paper presents a set of 930 MHz measurements conducted along the "Zhengzhou-Xi'an" high-speed rail of China, to characterize short-term fading behavior of the rail viaduct scenario. Three measurement cases covering viaducts with different heights are reported. The analysis results include Fade Depth (FD), Ricean distribution fit and K-factor modeling, Level Crossing Rates (LCR), and average fade duration (AFD). A small value of fade depth, around 15 dB, is observed. The Ricean distribution offers good fit in this Line-Of-Sight (LOS) propagation scenario, and the K-factor estimated using moment-based method is modeled as a piecewise function, whose break point equals to the reference distance.
