As may be expected, the industries expand, and with this growth the demand for infrastructure system especially in transportation system supporting logistics system and network activities apparently increases. However, unlike in developed countries, roadway system in Thailand has been largely invested countrywide, while the investment in the railway and its facilities system considerably declines. Consequently, the Thai railway system tends to lose its competitiveness to the road transportation, despite of its several advantages such as the high efficiency, large freight volume, cost effectiveness, time punctuality, speed safety and low energy consumption, specifically at medium to long distance transportation [15,16,17]. Moreover, while the railway system investment requires construction of own infrastructure and needs to bear with large debt payment, road construction investment experiences relatively low risks of return. This is because the road users are subsidized in that charges they pay do not cover the full cost or even the marginal cost of using the roads, whereas the railway costumers need to pay in full. This makes the investment of railway system in Thailand becomes even more challenging.
