In fact, railways mode are more efficient at transporting bulk freight traffic over medium to long distances. It can also effectively handle large volume of transportation with time punctuality, speed safety and lower energy consumption, compared to their main rival, the trucking industry [1,2,3]. However generally in Thailand, agriculture product such as rice, coconut and sugar, and secondary products such as machines and consumer products, depends largely on truck transportation. As a result, very few portions of these cargoes being transported by rail, despite of its several advantages of large-volume services offered for bulky cargoes. It is a straight choice for those logistics transportation service providers to save their cost by switching the mode of transportation from road to rail. Accordingly, it is of great importance for government to enhance service expansion in the country and promote the use of railway amongst the transportation sector.
