BSR, the entity awarded the contracts, is a Joint Venture between BTS Group Holding, Sino-Thai Engineering and Construction (STEC) and Ratchaburi Electricity Generating Holding.

Thai economist and Deputy Prime Minister Somkid Jatusripitak witnessed the signing of the contracts, implemented as planned under a Public Private Partnership (PPP) scheme.

Under the PPP arrangement the Thai government will be responsible for the acquisition of land and for providing funds for approximately 43% of the projected cost of the civil works, while BSR will be responsible for construction, will install machines and electricity, and will provide train Operation and Maintenance.

The contracts are split into two phases: the first for construction, lasting 39 months, the second for operation, lasting 30 years.

The 35.5 km long Pink Line will run between Khae Rai and Min Buri.

The 30.4 km long Yellow Line will run between Lat Phrao and Samrong.

BTS Group Holdings Founder and Chairman Keeree Kanjanapas stated that construction of the two monorail systems would begin shortly and that they would be in operation by 2020. “After we agree on the trains and all the land is surveyed we can begin the construction work, in this year.” BTS Group Holdings is the operator of Bangkok’s famous elevated Skytrain.

Mr. Kanjanapas also stated that a 2.8 km extension of the Pink Line and a 2.6 km extension of the Yellow Line are in the pipeline.

The BSR Joint Venture reportedly signed three other contracts on the day, all related to the two monorail projects:

  • financial agreement to support loans from Bangkok Bank
  • construction contract with Sino-Thai Engineering and Construction
  • contract for mechanical and electrical systems with Bombardier

    Mr. Jatusripitak said that the government would soon open bidding for the Red Line from Salaya to Hua Mak, the western extension of the Orange Line from Taling Chan to Ratchada and the southern section of the Purple Line from Bang Yai to Ratburana. All utilizing the same PPP scheme.

Pink and Yellow Lines construction contracts signed, operational in 2020

The Mass Rapid Transit Authority of Thailand (MRTA) yesterday signed two electric rail route contracts , the Pink Line and the Yellow Line, with the BSR Joint Venture worth 100 billion baht.

The new electric rail lines will enable people in Bangkok outskirts, Nonthaburi, Samut Prakarn and surrounding provinces to travel into the inner zones of the capital more conveniently.

They will connect the existing electric train routes and under construction routes namely the Blue Line, Purple Line, Green Line, Orange Line, and Red Line.

Construction of the two rail routes are scheduled to be finished and begin operation in 2020.

Witnessing the signing of the contracts was deputy prime minister Somkid Jatusripitak.

He said the two projects would be the first pilot projects to be implemented under the government’s public private partnership (PPP) fast track scheme.

This will greatly ease traffic congestions in areas where the Blue Line and the Purple Line are on service.

BSR Joint Venture is 75% held by the BTS Group Holding, while the state-owned MRTA currently oversees the operation MRT subway rail services, the Blue Line and the Purple Line.

The Pink and the Yellow Line projects could be considered as the starting points to complete the mass transportation network in Bangkok.

The 46-billion baht and 34.5 kilometre Pink Line will run from Khae Rai to Min Buri district with 30 stations. It will be monorail system linking Nonthaburi and Bangkok.

The first station will begin at the Government Complex in Nonthaburi.

The interchange will be at the Government Complex which will connect with the Purple Line which run between Bang Yai and Bang Sue. It will also connect the Orange Line at Min Buri station.

The 45-billion baht and 30.4 kilometre Yellow Line will run from the Lat Phrao area to Samrong in Samut Prakan. It will be also monorail system with 23 stations, starting at Ratchada-Lat Phrao station and ending at Samrong station.

Monorail plans finalised for approval

MRTA gears up to sign monorail deals

Amornrat Mahitthirook

The Mass Rapid Transit Authority (MRTA) aims to sign construction contracts early next month for the two key electric rail lines that will carry people from surrounding provinces to the capital.

The two monorail projects involve the 30.4km Yellow Line, worth 52 billion baht, which will stretch from the Lat Phrao area to Samrong in Samut Prakan, and the 34.5km Pink Line (53.5 billion baht), which will run from Nonthaburi’s Khae Rai to Bangkok’s eastern Min Buri district.

MRTA deputy governor Theeraphan Tachasirinugune, who is in charge of strategy and planning, said the agency will forward the project plans to the cabinet for approval late this month.

A selection committee formed under Section 35 of the 2013 Private Investments in State Undertakings Act has vetted details of the two projects, negotiated project prices with the bid winner and come up with conclusions, according to Mr Theeraphan.

The results of the negotiations have also been sent to the State Enterprise Policy Office and the Office of the Attorney-General for consideration.

The deputy governor said the deliberation work has now been completed. The MRTA is waiting for this to be returned to the Transport Ministry so it can be presented to the cabinet for approval.

The construction and installation of operation systems for the two projects is expected to be wrapped up within three years and three months of the contracts being signed, Mr Theeraphan said.

But these contracts do not include proposals by BSR Joint Venture to further extend the two lines.

It has proposed extending a 2.6km section from the Yellow Line’s Lat Phrao station to the Ratchayothin station on the Green Line (Mor Chit-Saphan Mai-Khu Kot) as well as a 2.8km section from Chaeng Watthana Road to Muang Thong Thani on the Pink Line.

Both extension plans would require environmental impact assessments (EIA) and feasibility studies to be carried out first, according to Mr Theeraphan.

The bid winner would be responsible for all the costs of the line extensions, including construction and land expropriation, while the MRTA would play a coordinating role, he said, adding that the two extensions are not binding on the main projects.

He said the extension plans may be scrapped if a deal cannot be made.

The work on the Pink and Yellow lines will be carried out under the Private-Public Partnership net cost model, he added. Under this approach, the private sector will shoulder the cost of construction, civil engineering, operation systems, electric trains and service, maintenance and fare collection.

The concessions will be granted for 33 years and three months, Mr Theeraphan said.

Transport Minister Arkhom Termpittayapaisith said earlier the MRTA will ask the cabinet in June to approve three more electric rail line projects projects Meaning: a planned piece of work that is designed to find information about something, to produce something new, or to improve something Thai Translation: โครงการ Learn more .

They are the 8km Blue Line extension (Bang Kae-Buddha Monthon Sai 4), the 16.4km western Orange Line (Thailand Cultural Centre-Taling Chan) and the 23.6km southern Purple Line (Tao Poon-Rat Burana). The total estimated cost is 275 billion baht.
