Abstract

Studies have been carried out on a rail brake applying linear induction motor technology, called LIM-type rail brake. This brake is capable of generating braking forces without contact. In addition, this method decreases the rise in rail temperature, and no onboard supply is required by using dynamic braking. It is necessary however to install this brake between front and rear wheels of the bogie. A prototype rail brake system was designed and built and its electromagnetic characteristics were examined on a test bench with a roller rig. These investigations revealed that the LIM-type rail brake could be applicable for practical use.
