Feasibility Study of Multimodal Freight Transport using Trucks and Trains (Sisaket-Laem Chabang Port)

Abstract

This study examines the feasibility of developing a multimodal transport system along the Sisaket–Laem Chabang corridor, focusing on the integration of road and rail networks to enhance cost efficiency and competitiveness in Thailand's logistics sector. A qualitative methodology was adopted, involving in-depth interviews, focus group discussions, and field surveys with key stakeholders, including transport operators, exporters, government officials, and representatives from the Sisaket Chamber of Commerce. The primary commodities on this route are cassava and sugarcane. The results show that implementing a multimodal transport approach could reduce transportation activity costs by 4,910 Baht per trip representing a 40.92% cost saving compared to conventional road-only transport based on the Activity-Based Costing (ABC) framework. Project feasibility analysis revealed an internal rate of return (IRR) of 15–18% and a payback period of approximately 7 to 8 years. Ban Nong Waeng Station was identified as a strategically located site suitable for development into a small-scale distribution hub and rail-road transfer point. Despite its potential, the proposed system faces infrastructure-related limitations, such as the inadequacy of transshipment facilities and weak rail-road connectivity in rural areas. To maximize the system’s effectiveness, policy support and public investment in infrastructure development will be essential. This study contributes practical insights into multimodal planning for regional logistics networks in emerging economies.
