52

According to the results of the study of economic, environmental, and preliminary design, the
Yellow Line Transportation System Project operated by the Office of Transport and Traffic Policy
and Planning (OTP) divided the project route into 2 phases: Ratchada / Ladprao - Pattanakarn
Section and Pattanakarn - Samrong Section. However, in the study of system design in this project,
the two routes were merged into one route throughout the route, and the system used as a monorail
system, with details as follows.

Ratchada / Ladprao-Pattanakarn Section

The beginning of which the connection point to the MRT Chaloem Ratchamongkhon Line
(Blue Line, First Phase) at Ratchada-Ladprao Intersection along Ladprao Road until Bang Kapi
Intersection, Then the line will turn south along Srinakarin Road connect to the Orange Line at the
intersection of Lam Sali , end the route at the Rama 9 Intersection, connecting to Suvarnabhumi
Airport (Airport Rail Link), a total distance of 12.6 km, with approximately 11 stations.

Phatthanakan - Samrong Section

The beginning point at the connecting point with the Airport Rail Link at Rama 9 Intersection
along Srinakarin Road, pass Phatthanakan Intersection, Sri Nuch Intersection, Sri Udomsuk
Intersection, Sri Iam Intersection until Sri Thepha Intersection, Then the line will divert to the west
along Thepharak Road through the connection point with the MRT Green Line project Bearing -
Samut Prakan Section At Samrong Station and end the route around the road of Pu Chao Saming
Phrai, a total distance of 17.8 km, has approximately 11 stations.

Note: There may be changes in the station area as appropriate.

Station

There are 23 stations, all stations (with the extension of another two stations in the future) are
all elevated stations. The station has a length of 150 metres and can accommodate a maximum of
7 cars per train using all side platforms. There is a half-height platform barrier gate at every station.
The station is designed to avoid utilities both on the ground and underground. Including designed
to maintain the road surface as much as possible and there are posts to hold the station in the street
isle and free space in some stations.

53

Structure of Runway

Typical elevated runway structures used in the project must have a beautiful appearance that
supports the rail of monorail in two-direction Guideway Beams, running along the path in the
project and the runway structure will be placed in the street isle as much as possible. In order to
reduce the impact on the surrounding people, avoid the expropriation of the land of the people to
a minimum, and must be able to construct easily and quickly to reduce traffic problems during
construction.
The elevated runway structure consists of 2 main parts:

54

1. Superstructure

The consultant reviewed the original study results by determining the beam span, beam size,
and design as a set of continuous beams with a typical span of 25 micrometres, 5 consecutive spans
(5 × 25 = 125 metres), and a general span of 29 metres long, 5 spans, continuous (5 × 29 = 145 m)
to reduce the number of piles, foundations, pile quantity, bearings, and use a prefabricated beam
structure model from the factory to be assembled on the construction site to provide faster
construction and better control of material quality.

The layout of runway structure , general length range 5 × 25.0 = 125 m.

The layout of runway structure , general length range 5 × 29.0 = 145 m.

55
In the event that a typical long runway structure cannot be used, the consultant will do design a
runway support structure that is a series of 2 to 5 continuous beams with a span of beams between
25, 29, and 35 metres.

The layout of the runway structure spans a special length range of 35-35 metres.
The case where the runway structure must cross a road intersection and requires a runway that is
longer than the general runway, special length range 40-60-40 metres.

The layout of the runway structure spans a special length range of 40-60-40 metres.

56

2. Substructure

The consultant reviewed the original study results by aligning the columns in accordance with
the span of the beams supporting the track structure of the monorail and to avoid impacts on the
demolition of utilities. The consultant has considered using a bored pile and a barrette pile. By
placing the end of the pile on the second sand layer, so that the pile can support the weight more
safely. Causing the number of piles in the foundation to decrease, will reduce the size of the
foundation and it will help reduce the problem of subsidence and the difference between the
foundation of the runway and the road. The structure of the column used in the project has both a
single column supporting two-way runway beams, in case that the column can be placed on the
street isle, single column with eccentric pile support two-way runway beams, single column
supports one-way runway beams, or in double-column or portal frame designs, in case that the
column can not be placed on the street isle

58
In the event that there is a large water pipe in the center of the road and it is more than 2.00 m from
the road surface in order to avoid the problem of removing the pipes from the line of the runway,
the consultant has designed a single column, placed on a foundation of 2 piles by placing it across
the pipe line to solve the problem.

Station design

Station design ideas

The overview of the railway station is the design of the Monorail station that will have the
characteristics and space sufficient to meet the needs of the vehicle. Which will have different
proportions for each manufacturer. But the station must be designed to accommodate the monorail
of each manufacturer by reducing or adding some distances that will be adapted to the vehicle
Monorail initially, along the route will be used as an elevated station, which will have different
heights along the route and the restrictions of that station area and designed the station to have a
beautiful roof and ceiling shape. When viewed from the bottom of the road, the roof must block
the sun and rain without hindering the natural light.

Station configuration has set out to have 3 forms according to the platform arrangement and
planning of the railway management system and area constraints are as follows:

Two-level side platform: a station with two side separate platforms outside of the station. The
platform will be flanked by two adjacent rail tracks with a passenger hall in the middle. There are
2 levels below the platform below.

Three-level side platform: There is a station with two separate platforms outside the station,
which is flanked by two adjacent railway tracks. There's a passenger hall in the middle. Below the
platform and a multipurpose floor on the ground floor. There are 3 levels.

Central Platform: The station has a central platform, flanked by a separate railway line, and
a passenger hall in the middle. There are 2 levels below the platform.

The design of the station structure will be consistent with the architectural design as well as
provide a strong and safe structure, has a long service life, and easy maintenance. The design is
performed in accordance with international standards.

The station structure of the project is an elevated station located mainly on the street isle. The
structure of the column building is 25.00 – 27.50 metres apart, as appropriate for each station. The
beam design is used as an I-Girder or U-Girder beam, pour over the casting floor in the entrance
and exit of the station on the side. On both sides of the station are reinforced concrete building
structures. The base is used as a drilled pile so that it does not affect the neighboring area.

Depot

The depot building is located at the intersection of Srinakarin Road and Bangna Trad Road.
Near the park and ride building and Sri Iam station. The depot building consists of 3 main
buildings: Main Workshop, Stabling Yard, and Office Building, and bus control building
(Administrative & Operation Control Center)

The idea of designing a depot and parking is to use natural light and air vents, as they are quite
wide and tall buildings. Therefore, air and natural light come from the roof area. In the living

60

areas of the room, such as spare parts, the work area is arranged on either edge of the building.
Administrative ventilation can be achieved by minimizing the area where air conditioning is
used. Especially in the hall and other rooms, For example, the direction of the building must be
properly positioned to ensure good ventilation. As for the Operation Control Center is the office
of all operations control, so safety must be taken into account. There must be controlled limited
access. There is a restaurant for 100 staff, which is clearly separated from the main building. To
reduce problems that may arise from uncleanness.

Park and Ride

The park and ride building is one of the most important elements of the train ride. It is where
passengers can switch from traveling by private car to electric train in order to transport into the
city. The Center design concept is designed that the traffic route is not congested and the car is
separated from the pavement clearly for safety. The carriageway is organized as a one-way and a
split-level building with ramps in the appropriate positions, make the car out quickly in the rush

hours. At about every 60 metres, there are stairs and a restroom, where there is a fire hose cabinet
in the area. External walls have at least 50 percent openings to drain.

Joint Venture Agreement

The Cabinet passed a resolution on March 29, 2016, to approve the operation of the MRT
Yellow Line Project, Ladprao - Samrong Section, a monorail system in the form of a Public-Private
Partnership (PPP Net Cost). The government sector (MRTA) invests in land and private ownership
in civil works. Electric train systems and electric trains, including operating and maintenance
services. The private sector is allowed to invest for a total of 33 years and 3 months, which is a
construction period of 3 years, 3 months, and duration of operation of 30 years, and approves the
budget of the project expenditures and the private support framework to support civil work in the
amount not exceeding 22,354 million baht. By gradual payments to the private sector after the
commencement of the opened service and split annual payments by stipulating a payment period
of not less than 10 years, the Ministry of Transport and MRTA must strictly follow the procedures
of the Private Investment in State Affairs Act in 2013, and when the private sector has operating
results beyond the agreed level, it should also consider the appropriateness of determining the
revenue share from the better operating results.

On May 30, 2017, the Cabinet passed a resolution approving the results of the private selection
and drafting of the concession agreement for investment, design, construction of civil works,
procurement of electric train systems, train operation, and maintenance services of The MRT
Yellow Line Project, Ladprao - Samrong Section, with Eastern Bangkok Monorail Company
Limited (Eastern Bangkok Monorail: EBM) as the concessionaire of the project, MRTA and EBM
signed the contract on June 16, 2017. Eastern Bangkok Monorail Company Limited was registered
and established under Thai law consisting of BTS Group Holdings Public Company Limited, Sino-

Project Background

In the meeting held on 9 March 2010, the cabinet acknowledged the 8 February 2010 meeting
approval of Mass Rapid Transit Master Plan in Bangkok Metropolitan Region by Land Traffic
Management Commission. The Master Plan requires all related government agencies to implement
respective first phase projects within 10 years – all services should be fully operate in 2019 – which
consist of 7 MRT lines with a total length of 154 km and MRT Orange Line Taling Chan-Min Buri
project is one of them.

According to the cabinet resolution passed in the meeting on 11 January 2011, Mass Rapid
Transit Authority of Thailand (MRTA) is authorised to transfer any remaining budget of other
MRTA projects to engage a pre-construction consultants for MRT Orange Line Taling Chan-Min
Buri project. In this regard, MRTA employed Bangkok Mass Transit Orange Line Consultants
(BMTO) to conduct a study, review the design specifications, prepare tender documents and
operate under the Private Participation in State Undertaking Act B.E. 2535

MRT Orange Line Taling Chan-Min Buri project is a heavy rail project with a total length of
39.8 km divided into 2 sections, the west section and the east section. The west section is called
“Taling Chan- Thailand Cultural Centre” and east section called “Thailand Cultural Centre – Min
Buri” which MRTA, with cabinet approval on 9 April 2016, proceed with the construction and,
later on 9 February 2017, signed the civil works contract with all 6 contractors. The contracts
signing ceremony has Mr.Somkid Jatusripitak Deputy Prime Minister as the Chairman, along with

Civil Works Structure
1. Underground Structures (Tunnel)

In general, the underground construction, in MRT Orange Line (east), consists of twin bored
tunnels approximately 6.3 meters in diameter and 6.3 meters apart in horizontal configuration but
in some area, due to construction constraint by area or existing bridge foundation, the twin tunnels
has to be stacked or cut&cover tunnels has to be built instead.

3. Station Structure
MRT Orange Line (east) “Thailand Cultural Centre – Min Buri” has both underground and
elevated station divided in to 10 underground stations and 7 elevated stations as follows.

71

The MRT Orange Line, Thailand Cultural Centre - Min Buri, has been changed to name 3 stations:
1. Hua Mak Station changed to Ramkhamhaeng 34 Station.
2. Lam Sali Station changed to Yaek Lam Sali Station.
3. Suwinthawong Station changed to Yaek Rom Klao Station.
1) Underground Station

There are different underground station models based on the characteristics of the deck platform
configuration for passengers. The three typical types of configuration as follows: central platform,
a station with rail alignment at each side of the platform and a single concourse located directly
above. This configuration is most typical one.

72

Central platform
Next, stacked platform, a station with two levels for side platforms and a single concourse
located above. This configuration is applied where the existing bridge impede the construction of
tunnel and limit R.O.W. and stacked tunnels have to be constructed.

Stacked platform

73
Last, side platform, a station with twin platforms each side of central rail alignment with a
single concourse located directly above. This configuration is applied when cut and cover tunnel
is employed.

Side platform
There are structure for ventilation at the head and the end of each station for air circulation in
the station area. In the event of a fire, this structure also allows the officers to take control of the
situation and helps to evacuate passengers from the platform.
2) Intervention Shaft
The main function of an intervention shaft is to relieve air pressure from the tunnels. Since
tunnel size is a little larger than train, when the train runs inside the tunnel, it will act like a piston
and increase the air pressure. It is necessary to vent the air pressure to the outside. In addition,
when the underground station is located more than a kilometer away, the intervention shaft act as
an emergency exit to serve as the evacuation point for passengers in the event of an accident. For
this project, there are total of 11 intervention shafts.

74

Intervention shafts
3) Elevated station

Almost every elevated station has a layout of a sided platforms. The station is divided into 2
levels: Concourse level, approximately 8 meters above road level and platform level,
approximately 15 meters above road level. The station is approximately 150 meters long and 25
meters wide and supported by a column every 30 meters on the road median.

In general, there are 4 entry point to an elevated station, located at every corner of the station
and the adjacent entry point can be used as a crossroads for people.

Western Project (Bang Khunnon - Thailand Cultural Centre) (in the bidding
process)

The Phase 2 Western extension of the Orange line will run from Thailand Cultural Centre to
Bang Khun Non via Pratunam. The 17.5km western section will run underground with 12 stations.

The Thai Cabinet was expected to approve the 121 billion baht budget for the Western extension
in mid 2017 with a tender due for the 2nd half of 2017. However, this decision was delayed until
2018 as Cabinet requested options to be considered for a joint public and private investment
proposal. There were further delays into 2019, but the MRTA finalised a joint PPP plan for Cabinet
to approve in mid 2019. On 28 January 2020, the Cabinet approved the 142 billion baht extension.
It is expected to open in February 2026 and serve 439,000 passengers daily.

On 3 July 2020, the MRTA released the tender for the design, construction and operation of the
Western extension as a Public-Private Partnership project on a 30 year lease.The tender closes on
23 September 2020 with the successful bidder expected to be announced in early October 2020.

Route

The Brown Line starts at Nonthaburi Civic Centre where it interchanges with both the MRT
Purple Line & MRT Pink Lines. It heads east along Ngam Wong Wan road to Khae Rai
intersection and then Vihavadi-Rangsit road to interchange with the SRT Dark Red Line at Bang
Khen. The Brown line continues past Kasetsart University to interchange with the BTS Sukhumvit
Line at Kasetsart University on Phahon Yothin Road. The line continues east along Prasote
Manukitch Road (AKA Kaset-Nawamin Road) past Chalong Rat Expressway (interchanging with
the proposed BMA Grey Line) to Nawamin Road. It then turns south along Nawamin Road over
Lam Phang Phuai and past Klong Chan Stadium. The line continues southeast along Nawamin
Road where it terminates at Ramkhamhaeng rd (soi 129/1), Lam Sali junction to interchange with
the MRT Orange Line and MRT Yellow Line.

Project format

• Straddle-beam monorail system
• Runway elevated at a height of 12 metres throughout the project
• There is a 3rd track hitting parallel to the track to supply electricity to the vehicle

• The vehicle is a wide air-conditioned vehicle. 3.147 meters ， length 11.8-13.2 meters ， height
about 4.06 meters (when all the rails are straddled) capacity 356 people per vehicle (calculated
from the density rate of 4 people / square metre) per bunch, 2-8 cars per train using direct current
electricity 750 volts supply the vehicle power system, can accommodate 24,100 passengers per
hour per direction.
• Use the automatic signaling system from the bus control center and use the automatic fare
collection system, just like the Yellow Line train and the Pink Line.

Depot and operation control center

The project originally studied depot at the Chalong Rat Expressway intersection, but since that
area, Bangkok will be expropriated for the construction of the Gray Line Railway Project's depot.
Therefore, the project has the concept of moving the depot to a nearby area or moving to Bang
Kapi Junction, which is close to the Lam Sali Intersection.

Initially, the project depot will have a total area of 44 rai, consisting of a garage building, depot,
building changing wheels, management system control, and the project management office

Park and Ride

A park and ride at Seri road, close to Lam sali station of MRT Orange Line, parking about
2,000 cars

Station

Brown line is proposed to have between 20 and 23 stations:

The project designed two station layouts as follows:
• Normal structure station. The station is approximately 150 meters long and has a platform screen
door, half-height. All stations are designed to avoid underground and above-ground utilities and
maintain the most road surface conditions. There are station posts on the street isle and there is a
ticketing floor under the platform, there are 10 stations.

89

• Structural stations under the expressway. The station is approximately 150 meters long and has
a platform screen door, half-height. Every station is designed to avoid underground utilities on the
highway and maintain the traffic surface on the road as much as possible, with posts to hold stations
on the street isle in the middle of the 3rd stage expressway, North Line N2. The ticket office is
located in the area of the station entrance building which will split the side to Nonthaburi and the
Lam Sali side clearly. In this study, the construction of pedestrian bridges in every station has been
established or there may be a construction of a crosswalk at every station in order to facilitate
crossing to the other side, there are 10 stations.

Light Rail Project Value

On February 1, 2021, the Mass Rapid Transit Authority of Thailand has presented a preliminary
study of electric train technology for the project which consists of 3 forms: light rail with steel

95

wheels, Light rail with rubber wheels, and the Autonomous Rapid Transit system to the
Commission for the Management of Road Traffic.

Because when comparing the budget between using the light rail and the Autonomous Rapid
Transit system, it is concluded that using the Autonomous Rapid Transit system costs only 17,723
million baht, which is half the price. Compared with using a light rail that costs 35,201 million
baht

On March 15, 2021, Mr. Sak Siam Chidchob, Minister of Transport, followed up on the project
progress. The additional command is:
1. Find a conclusion of the trained model that the system will use. Between light rail with steel
wheels, light rail with rubber wheels (Golden Line), and the ART (Autonomous Rapid Transit)
system, which costs more than half of the budget.
2. Provide OTP, together with EXAT and MRTA, to review the overall picture estimate of
passenger volumes in Phuket Phuket Expressway and Mass Transit System To ensure that both
projects in both phases will have passengers to use the service as expected.
3. Let MRTA set the new fare accordingly. Where the price is not too high and can induce the
private sector to join in.
4. Let MRTA consider using construction techniques that take the least time to reduce the traffic
impact. Since along the project route, it will pass through areas with heavy traffic problems
already. It will accelerate the first phase of the Phuket International Airport – Chalong Intersection
to be ready for service in 2026.

96

The first phase of the project is:
• In 2021, proposed to the Cabinet for approval in the form of joint investment in the project
