Korea High-speed Railway (HSR-350x) was developed by Korean government, several institutes, and related companies. HSR-350x was investigated its performance and tested at the high speed line. In 2004 December, HSR-350x was run over 350km/h and proved its running performance. And Korean Train Express (KTX) served the commercial traffic for 4 years. These high speed railways have 12 motors to transfer the traction effort or the braking force. To obtain the load of the transfer shaft, it is necessary to measure the transferred torque of the shaft. In this paper, authors propose the construction the measurement system fur monitoring the force transferred to the train from the motor The system was installed to the tripod shaft which is located between the reduction gears and it measures the mechanical load directly.
