Research on applying structural health monitoring to railways is now available on DEStech Publications' web site. The focus of the research investigations is how SHM technologies are used to determine the condition of virtually every component of a rail line, including rolling stock, motors, track, ballast, coupling, welds, and bearings—as well as infrastructure such as bridges and tunnels.

The ballast bed becomes loose in the event of earthquake, as to track lateral resistance ability, even if no visible defects are found in onsite inspections. The behavior of ballast materials subjected to earthquake vibrations is dependent on a variety of factors, including amplitude, frequency, as well as the particle properties, for example, ballast degradation.
