Abstract In Malaysia, rail transportation has become an integral part of the society. It can be seen by the effort of the Malaysia Government to improve the rail system by laying new route, provide new type of trains and others. For transporting goods, Malaysian rail authorities (Keretapi Tanah Melayu Berhad) used 22 coaches so-called freight train becoming one of the most popular transportation in delivery goods. In the past, wood is commonly used as a material in sleeper’s manufacturing but nowadays, prestressed concrete sleeper starts to capture their name in the industry in producing more quality sleeper as one of railway track components. This study will be focusing on determination of constant amplitude for 22 coaches, cyclic counting strain and calculation of frequency of strain on prestressed sleeper subjected to freight train. Rainflow cyclic counting method is used to determine the constant amplitude, cycle and frequency for each parts of train body. By using rainflow method and formulas, average number of cycle and frequency is obtained. From the obtained results, the individual PCS have to endure a maximum frequency and number of cycles of 11.91 Hz and 1.39 s, respectively. The outcome of this study will have a formulation of the freight train that is currently being used in Malaysia.
