A proposed project entitled “Fast Train Track Quality Measurement Using Gyro Sensors” has been conducted for vibration detection system on railway track. This paper is to describe the collection of vibration data on a train coach to see patterns of abnormalities along the way from Batu Gajah station to KL Sentral station. Focusing on designing a portable vibration system that can detect the deformation of railway track with good accuracy of accelerometers, and gyro sensors. Data collected from the system was analyzed where abnormalities are identified and compare relative to location of railway track. While the Direct-Cosine-Matrix (DCM) was applied to get the raw data from the Inertia Measurement Unit (IMU) sensor for both acceleration and tilt movement of the train. Using MATLAB, data processing will be take part in converting the data into graphs for differentiating the vibration noise and real data. To reduce the high frequency vibration from the train itself, low pass filter (Finite Impulse Response) will be program along the data processing to get better visualization of the vibration itself. Throughout the testing, few locations has been identified for abnormalities of the vibration movement from Rawang to Kuala Lumpur Station. Due to this abnormal vibrations, the comfort level in passenger is low as compared the final testing of the system.
