Railways are one of the most popular means of mass transportation systems. The proposed approach has a universal characteristic that can be applied by cities or authorities to design a strategic plan of urban transportation systems that can solve advanced transportation problems. This study focused on designing a new railway network between two big cities in Malaysia—Kuala Lumpur and Kuantan. The simulation model applied for planning the new railway design and analysis is an important factor. The overall objective of this approach is to increase the advantages of passenger service and public transportation systems as well as to make available other transportation means between these two cities. In addition, the model will also choose the best railway network that can accommodate more passengers along the routes between these two cities.
