To provide a program and a particular method which, with a simple structure, can accurately identify rail normal joint time positions.SOLUTION: A method for identifying rail normal joint time positions includes: a step S7 of executing an envelope extraction process S3 for the running sound of a train after noise removal to identify candidate time positions of the sound of rail normal joint time positions from the extracted envelope; a step S9 for generating the hypothetical time positions of the sound of the rail normal joints from the rail length data stored in a storage part that stores the rail length data in the train traveling area; and a step of collating the candidate time positions with the hypothetical time positions to identify the time positions of the sound of the rail normal joints.SELECTED DRAWING: Figure 3
