Provided is a state monitoring system that presents an appropriate repair time for a structure of a railway vehicle. In order to solve the above problem, in one representative state monitoring system 20a for a railway vehicle 1 according to the invention, a vibration generated due to stress or strain is detected using a vibration sensor 5 provided on a vehicle body and a truck 4 of a railway vehicle; traveling speed information or traveling section information, and distance information are acquired from vehicle operation information of a vehicle information management system 6; a frequency analysis result for a vibration generation frequency is prepared, the frequency analysis result being calculated for each traveling section based on the vehicle operation information and the vibration information. A cumulative frequency at a current time point is calculated based on the vehicle operation information and the frequency analysis result up to the current time point; a remaining life and a time thereof are calculated based on a future cumulative frequency predicted based on an operation schedule or an operation record; and a repair time of the railway vehicle is output.
