When a hydraulic converter is operated under the stall condition, the input power is fully absorbed into its converter oil. In such a case, the input power absorbed can be estimated from the revolution speed of the converter's input shaft or the heat quantity of the converter oil. Japanese railway companies are regulated to estimate periodically estimate the engine performance of hydraulic railcars. The authors proposed to apply the above mentioned principle to the estimation of the engine performance without dismounting the engine from the railcar. This paper describes about the process how the new method is useful to be of practical use.
