Abstract

Korean Train Express (KTX) has opened to commercial traffic since 2004 at maximum speed 300km/h, and Korea High-speed Railway (HSR-350x) was developed by Korean government, several institutes, and related companies. HSR-350x is now being 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. These high speed railways have 12 motors to transfer the traction effort or the braking force. In this paper, authors propose the construction the measurement system for monitoring the force transferred to the train from the motor. The system is installed to the tripod shaft which is located between the reduction gears and it measures the mechanical load directly.
