Double Track Project

Railway infrastructure is mostly single track that leads to rail traffic congestion. Overburdened tracks in some areas of network obviously cause congestion, delays and accidents. To solve these problems, increasing potential network, developing transportation and logistics system including relevant development plans are needed. The Thai government promotes railway system as an effective solution.

In this regard, the 2015 – 2022 Thai Transport Infrastructure Development Strategy has been formulated which track doubling projects are included.

New Main Line

Despite the fact that SRT came up with many railway lines project many years ago, the construction has not been activated yet. At the present, the Double Track Projects are high priority.

The railway network will increase from 47 to 61 provinces after completion of these projects. Currently, SRT is preparing to budget for a feasibility study (F/S).

Bangkok Red Line Project

The construction of the first phase of Red Line, mostly elevated suburban railway, covers the route from Bang Sue – Taling Chan (15.26 km) in the Western Section, and the Northern Section, Bang Sue – Rangsit (26.30 km), and is funded by an Official Development Assistance Loan from the Japan International Cooperation Agency (JICA).

The civil work on the northern line commenced in March 2016, while the electrical and mechanical work has begun in June 2016. It is expected to complete in June 2020. When this project completed, the main station will be transfer from Bangkok Station to Bangsue Grand Station, the biggest central station in Southeast Asia. There are 4 floors;

  • Basement – Car parking and connecting to MRT Blue Line
  • Ground floor – Ticket offices, convenience shops, offices and waiting area
  • Second floor – 12 platforms of metre gauge train services (Red Line Commuter and Long Distance Train)
  • Third floor – 12 platforms of High-Speed Train services

High-Speed Train Project

High-Speed Train Project: Bangkok – Nakhon Ratchasima – Nong Khai

A Memorandum of Understanding (MOU) on the cooperation of the development of rail infrastructure was signed between the government of the Kingdom of Thailand and the government of the People’s Republic of China on 19 December 2014. Thai Prime Minister, General Prayut Chan-o-cha and Chinese Premier, Li Keqiang had a bilateral discussion in the first Lancang – Mekong Cooperation Leaders’ Meeting on 23 March 2016. It is noted that the project would continue as a G2G basis and Thailand would become the sole rail project investor, starting from Bangkok – Nakhon Ratchasima and following further phases.

The Study and Design of High Speed Rail System, Bangkok – Nong Khai, Phase 2: Nakhon Ratchasima – Nong Khai, a total length of about 355 km, finally extended the scope of the study and design to cover the study and design of a standard gauge (1.435 meter) double track to accommodate the high speed rail system in the future. The study could be summarized in 2 cases as follows:

  • Case 1: Mixed Traffic denoted the study and design to accommodate a conventional train at the maximum speed of 200 km/h and a freight train at the maximum speed of 120 km/h.
  • Case 2: HSR only denoted the study and design to accommodate a high speed train at the maximum speed of 300 km/h without a freight train.

There would be 5 elevated stations namely Bua Yai, Ban Phai, Khon Kaen, Udon Thani and Nong Khai.

Feasibility study, definitive engineering and architectural design, preparation of tender documents and cost estimation.
