Rail transportation in Thailand began in
October 1890 when King Chulalongkorn His
Royal Highness ordered the establishment
of the Department of Railways. The first
railway line of the country started its
services on March 26, 1896

The first electrical rail transportation in
Bangkok was in form of tram. His Majesty
King Chulalongkorn, King Rama V, went to
the final ceremony of the burial of the last
knot for its rail construction on October 1,
1948. The tram route had been named the
"Dusit Line". Unfortunately, after the World
war 2 it had to close because insufficient
electric current.

Rail transportation in Bangkok began again
in 1999 as the first elevated electrical train,

To oversee the growth in rail transportation the
government established Mass Rapid Transit
Authority of Thailand : MRTA on August 21,
1992 to handle the planning and construction
of MRT.
MRTA constructed the first underground rail in
Bangkok, Metropolitan Rapid Transit Chaloem
Ratchamongkhon Line or MRT Blue Line from
Hua Lamphong to Bang Sue.

MRTA started the construction of Blue Line Extension
by the civil construction.
The construction was done in 5 contracts. 2 contracts
for the underground stations and tunnels, 2 contracts
for the elevated stations and viaducts (and depot) and 1
contract for the rail Trackwork.

The completed Blue Line allows
passengers from the western suburban to
reach the city center in a few minutes.
The Park and Ride facility at Lak Song
makes it even easier for passengers as
they could leave their cars in a safe and
secure location and avoid the inner-city
traffic jams.

Once the civil works are completed, all of the railway
systems can be installed and tested. These are known
as the Mechanical and Electrical works, or M&E works
for short, and for the Blue Line Extension they
consisted of the following systems:

RST : The Rolling Stock or trains, that carry the
passengers quickly, safely and in comfort, day
and night and whatever the weather.

PSY : The Power Supply System takes the electrical
power from the MEA network and distributes it
to the trains and stations

SIG : The Signaling System allows every train to be
monitored at all times and sends the instructions
to control the train routes, speeds and times

COM : The Communication and the Supervisory Control
and Data Acquisition (SCADA for short) systems
provide the means for all communications
between each of the systems, for example
between the Central Control Room and the
trains, or for giving all information for the public

PSD : The Platform Screen Doors ensure that
passengers are safely separated from the moving
trains, and only open once the train has
completely stopped.

AFC : The Automatic Fare Collection system allows
passengers to buy their tickets from vending
machines or from the ticket office. The swing
gates ensure that the proper fare is deducted for
every passenger and that their tickets are valid.

DWE : The Depot and Workshop Equipment is
equipped to allow the trains to be maintained
and repaired, and kept in a safe, reliable and
comfortable condition at all times

The trains, technically known as Rolling Stock are the most
visible part of the line, and the place that users will spend the
most time.
The new trains are similar in layout to the existing Blue Line train
fleet, but with upgrades to incorporate the latest technology
such as the passenger information display screens.

The trains are designed to ensure passenger safety and comfort
above all, as well as to be reliable and to give many years of
trouble-free service.

The main characteristics of the rolling stock are
• Each train is made up of three cars
• Stainless steel frame and body, for strength and corrosion

resistance
• A maximum service speed of 80 km/h
• Steel wheel based for standard gauge tracks of 1,435mm.
• 750VDC traction power collected by a collector shoe from a

wayside third rail
• One driving cab at each end of each train which have been

ergonomically designed to allow for safe driving by competent
operators.
• 8 Sets of electrical bi-parting doors per car (4 per side)
• Emergency evacuation door at each end of each train
equipped with a ramp
• Gangways for passengers to move between cars
• Mechanical and electrical coupling at each end of each train
for train rescue
• Air conditioning supplied in each car and adapted to the
Bangkok weather conditions
• Electrical and mechanical brakes for maximum safety and
comfort

2. Assembly in Vienna, Austria; completing the cars and the bogies

3. Shipment of completed
trains to Thailand

35

The main components of the car body are
made from Stainless steel and welded
together for strength and long life

The air conditioning system is
placed on the roof of each car.
It provides filtered and
temperature controlled air
throughout the train for
optimum passenger comfort

36

Under the floor of the train cars are many
of the systems to provide safe, reliable and
comfortable travel, such as the power and
braking systems

There is a bogie at each end
of each car. The bogies
include the main wheels and
suspension, as well as the
traction motors and brakes

39

Electrical power to feed the metro is supplied by the MEA at 69kV, at
two new Bulk Substations (BSS) in addition to the two already working.
The BSSs are built in accordance to MEA requirements and
internationally accepted standards. This includes control panel,
consumption metering, and protective devices. Power is received from
MEA at voltage level of 69 kV and transformed to 24kV by a power
transformer. The configuration of 24 kV switchgear is arranged to
ensure safety, high availability and appropriate redundancy for the
Blue Line. The AC distribution scheme will be provided with a
protection system to ensure that a faulty element is isolated, and that
no other plant is disconnected
Within the stations the power is further transformed into the
necessary voltage levels for the traction , and all other electrical
systems.

40

Rolling stock will receive power through the conductor
rail. This rail is called the Third rail as it will run along the
rails that support rolling stock wheels. This power is used
for the traction motors and for all train systems.
750V DC Traction power will be supplied to the Third Rail through substations that are carefully
placed to ensure an uninterrupted supply to the trains, wherever they are on the line.

41

The trains are in contact with the Operation Control Centre (OCC) at all times. A radio system has antennas on
the trains and on the trackside so that information about the trains position, speed and condition can be sent to
the OCC, and the OCC can give instructions to the train about the route and the speed profile to adopt. This is
known as Automatic Train Operation, or ATO. If another train or any other obstacle is on the track in front, the
train will be made to stop. This is the Automatic Train Protection, or ATP, and it will prevent collisions.

42

Equipment to monitor and control the train movements
The signaling system is based on fixed block operation in which the track is divided
into predetermined parts, each part known as a track section. The normal
operating rules require that a train does not enter a track section which is already
occupied by other railway vehicles.
This service proven technology has primarily been chosen because the Initial Blue
Line (IBL) is equipped with the same technology, providing a safe system for the
extension lines and at the same time allow for synergies in operation and
maintenance

43

The Supervisory control and data acquisition (SCADA) is a system that monitors
and controls the power supply to the stations and to the track

44

Passenger safety is ensured with the help
of walk-through metal detectors at the
entrance to the stations, and closed
circuit television (CCTV) cameras to
provide a view of every corner of the
stations.

Communication is essential for a modern transportation
system. A backbone fibre optic network connects all the
stations, and in particular the Station Operations Room
(SOR) to the Operation Control Centre. Broad-band radio
links all mobile functions to the fixed infrastructure. All
the necessary information for operating the metro is
transmitted through the communication system. For the
passengers, the most visible aspects are the display
screens, the public address (PA) announcing service
messages, and the clocks giving the precise time across
the network.

45

Platform screen doors for the safety of all passengers The Full Height PSDs in the four underground stations
Platform Screen Doors are provided on the Blue Line perform the additional functions of maintaining the
Extension, primarily for reasons of Passenger Safety. The integrity of the air conditioning on the platform and
PSDs prevent passengers from accidentally falling onto the maintaining the integrity of the Tunnel Ventilation
track and protect against injury as trains enter and leave a System. Both Full Height and Half Height PSDs are
station. Half Height PSDs are provided at 15 elevated available to support advertising panels.
stations. Sufficient PSDs are provided on each platform to support
ultimate operation with 6 car trains. Currently, only the
PSDs required for 3 car operation are equipped with the
requisite Local Control Panels and drive motors.

46

Automatic Fare Collection is fitted in all stations of the Blue
Line, in fact in all metro stations in Bangkok. AFC has
several purposes for the railway operator, including the
automatic collection of revenue, preventing fare evasion,
providing full journey information for all passengers,
recording all money transactions and preventing passenger
access in an emergency situation whilst allowing passengers
already in the station to escape. It is also possible to adjust
the price for journeys, for example during special occasions
or holidays. Passengers are encouraged to use the vending
machines for quick and easy purchase of their tickets. If
they need more assistance, they can also go to the ticket
offices at each end of the stations.

The Contactless Smart Cards and tokens used on the Blue
Line also work seamlessly on the Purple Line. In the future it
is planned that the AFC system of the Blue Line and the
Purple Line will be able to interoperate with all Bangkok
transport modes. The Blue Line system was designed to
make the conversion to interoperability as easy as possible.

47

Depot and Workshop Equipment
Keeping the trains clean, safe and reliable
The Depot and Workshop Equipment Subsystem is intended
to provide maintenance equipment and facilities to support
the efficient operation of the Blue Line System these includes
the existing Initial Blue Line System and the Blue Line
Extension System. The BLE Depot is supplement to the IBL
Depot and is mainly be used for routine cleaning, light
corrective maintenance of trains and the stabling of trains.
Provisions are made for the installation of additional
maintenance facilities such as train lifting system and
underfloor wheel lathe to allow the future expansion if
needed.
