Opportunity of frieght service expansion is actually relatively obvious in many areas of the
country. In fact, the demand of service lines in Thailand has been increasing annually during
the past ten years. Such demand has become apparent, for example, in the transport of
containers. Container transportation line, which connects between Laem Chabang (LCB) port
in the Eastern Seaboard (ESB) and Lat Krabang Inland Container Depot (ICD-Lad Krabang
or known as “LICD”) that lies on the SRT Eastern Line, has continuously increased its
transportation volume. This network offers highly promising opportunity for the service
expansion from existing single and triple track as shown in the schematic diagram in Fig. 1.
To respond to the further increase of container transportation, track doubling and expansion of
the Inland Container Depot (ICD) can be taken to consideration.
