1. Overview of Thailand Railway Transportation System
In the past, Thailand railway transportation was basically known as a passenger railway. Although its service included freight transport, the marketing focus was weighted toward passenger traffic. Railway was most frequently used for inter-city transport of passenger especially amongst the poorer levels of society. With the exception of the transport of some petroleum products, however, railway has captured only a minimal share of national total freight transport. This lack of emphasis on freight traffic, though, has begun to change over the past few decades. Nevertheless, the total revenues of Thai railway are relatively dwindling, caused primarily by artificially low fares for passenger traffic which had been imposed by the government. Therefore, it is most challenging for the Thai railway to capture more revenues
from freight traffic and increase its total usage share.
