1.1 BACKGROUND
The cabinet of Thailand acknowledged the conclusion of the Ministerial Committee on
Economic Meeting on 27th April 2011 which approved an infrastructure investment plan
for State the Railway of Thailand (SRT), Department of Highways (DOH) and the
Department of Rural Roads (DRR) for the sum of 195,820.50 million Bahts. The Ministry
of Finance and Bureau of the Budget have the responsibility for allocating appropriate
funding sources for the plan. An urgent stage of the Double-Track Railway Network
development in Northern Line, Northeast Line and Southern Line with a total length of 767
kilometers was considered as a part of the investment plan. The proposed Track Doubling
projects in the investment program include Lop Buri - Pak Nam Pho, Map Kabao - Thanon
Chira Junction, Thanon Chira Junction - Khon Kaen, Nakhon Pathom - Nong Pla Duk - Hua
Hin and Prachuap Khiri Khan – Chumphon sections.
In the consideration of consistency of cabinet’s resolution and policy in which Thai
Government encourages to invest both ongoing projects and potentially prospect projects,
Office of Transport and Traffic Policy and Planning (OTP), under the authority of Ministry of
Transport, has hired a consultancy to conduct the study and design of Prachuap Khiri Khan
– Chumphon Track Doubling Project which is one of urgent projects to be completed by
2015.
An increase in line capacity, a decrease in travel time and energy consumption in transport
sector an improvement in environment and efficiency of public transport in rural areas,
urban areas and international scale are benefits of the development of double track
railways. In addition, the development will encourage people to shift mode of transport to
railway, as a result, the accident rates on roads could be decreased. In this study,
passengers transport is not only the main consideration. Freight transport and tourism
potential are taken into account.
1.2 OBJECTIVES
1) Conduct a Study and Preliminary Design of the Track Doubling Project on Prachuap
Khiri Khan - Chumphon Section, aiming to propose suitable track alignment, right of
way, system infrastructures and integration with other transport modes
2) Conduct a Feasibility Study of the project in various aspects including Economic,
Social, Finance, Environment and the Investment Scheme
3) Conduct a Detailed Design, Project Cost Estimation and Tender Document Preparation

1.3 SCOPE OF WORK
The study scope consists of 4 main parts which are:
1) Survey and gathering data, literary studies and demand forecast
2) Feasibility study on Engineering, Social, Economic, Financial and Investment scheme
3) Detailed design and tender document preparation
4) Environmental Impact Assessment (EIA) Report preparation, public participation and
public relations implementation
1.4 DEVELOPMENT TARGETS
The development of Prachuap Khiri Khan - Chumphon Track Doubling, an urgent project on
the latest railway master plan depicted in Figure 1-1, is expected to improve the service
efficiency of rail transport in terms of speed, reliability, frequency and safety of both railway
operation and road users. The following targets are adopted for the design:
Railway structure and alignment are able to accommodate a maximum operating
•
speed of 160 km/h (except on certain areas where realignment is not practical or
worthwhile, the alignment will be designed for maximum operation speed of 120
km/h).
Signalling system, however, is designed to accommodate the maximum operation
•
speed at 120 km/h to be in line with the actual operation that could be expected,
i.e., currently SRT does not have plan to acquire the 160-km/h Rolling Stocks in the
near future.
Railway tracks can handle 20-ton axle loads.
•
Completely resolve at-grade crossing problems by upgrading to grade-separated
•
crossing.
Effectively utilization of the right-of-way which provides enough space for future
•
development
Minimize expropriation to reduce the social impacts
•
Provide an express service with 120-km/h maximum operating speed on the shared
•
track operation.
Support the future electrification
•
Support international connection
•
