In our previous researches, we estimated the reduced quantity of aerodynamic drag of trains by smoothing under-floor construction. However, we did not compare the results of wind tunnel tests with those of on-track tests, or verify the accuracy of wind tunnel tests for the aerodynamic drag of trains. In this research, we estimated the aerodynamic drag of a train-set by wind tunnel tests. Regarding the reduced quantity of the aerodynamic drag of trains, we compared the results of wind tunnel tests with those of on-track tests. These test results show that the reduced quantity of the aerodynamic drag of trains by wind tunnel tests approximately agrees with that by on-track tests.
