From 1995 to 1999, Siemens Transporta-
tion Systems was responsible for suc-
cessful implementation of the Bangkok
Transit System (BTS) turnkey project.
During that time, Siemens Transporta-
tion Systems substantially contributed
to providing an efficient solution for the
following initial situation.
The breathtaking rise of Bangkok to one
of Asia’s prime economic locations had
posed a fundamental problem to the city
fathers: how to ensure the mobility of
the millions of people who had to travel
through this boomtown every day.
An Efficient Urban Transit System –
Foundation for Economic Upturn
82% of all daily journeys were by bus,
car, motorbike or taxi. As a result, large
parts of Bangkok’s infrastructure were
congested and traffic jams were a daily
hassle. The travel speed in downtown
Bangkok was generally less than 10kph.
Not only commuter mobility was affect-
ed, but also the quality of everyday life.
The situation had deteriorated to the
point where Bangkok was suffering from
one of the highest levels of air pollution
in the world. Besides that, the popula-
tion of Bangkok had grown tremendously
– and with it private car ownership. So it
was no wonder that an efficient mass
transit system was seen as vital for the
further economic upturn of the city.
New Transportation Structure
for a Better Quality of Life
Therefore, Bangkok took on the huge
task of getting traffic moving again.
Not by simply expanding road transport
but by adding a railway infrastructure
to attract road users to other modes of
transport. That lessened the traffic
burden on the streets, cut exhaust emis-
sions and enhanced the quality of life in
the city.

Over the entire term of the project–from
the preliminary planning phase through
implementation to after-sales support –
all subsystems are optimally coordinated
to ensure the highest standard of quality
and safety. Internationally experienced
and superbly trained, our project manage-
ment team is there on the scene to act as
contact partner for the customer. Siemens
provides transparent and efficient project
management guaranteeing smooth pro-
gress and on-time completion of the work
as well as maximum availability of the
system. The result is that very often the
project is completed ahead of schedule.
The operator takes over a turnkey system
or subsystem that is tried, tested and fully
operational. On request, Siemens will even
assume responsibility for maintenance and
technical operation of the system. Satis-
fied customers and over 30 successful
turnkey projects worldwide testify to the
quality of mobility solutions from Siemens
Transportation Systems.

Turnkey Competence from Siemens
Attractive, cost-effective and environmen-
tally clean mobility solutions are needed
today more than ever before. Making
such transportation systems a reality is
an extremely complex task, which is why
they are often handled on a turnkey basis.
Siemens meets this demand by offering
not only technically innovative systems,
but also immense competence in project
management, system integration, project
development and financing to ensure that
operators the world over are supplied with
safe, efficient and customised solutions
that meet their transportation needs.
Highest Quality and Safety
When implementing turnkey projects,
Siemens Transportation Systems is in a
position to reduce interfaces, streamline
timetables and therefore consistently cut
costs. Cost-effective turnkey implementa-
tion starts immediately in the preliminary
project phase, when it comes to choosing
the right transport system or taking ad-
vantage of cost-saving potential offered
by existing system structures.

The Modern Traffic Solution –
Bangkok Transit System (BTS)
Bangkok Metropolitan Administration
(BMA) has initiated three mass transit
system projects. One of them represents
the most advanced type of urban rail-
way, the Bangkok Transit System (BTS),
an elevated heavy rail system running
above the business district of Bangkok.
The bottom line: it’s a safe, comfortable
and, above all, fast urban transit system.
The BTS comprises:
>the Sukhumvit Line, running
16.8km from On Nut to the
Mo Chit Bus Terminal
> the Silom Line, running 6.3km
from the National Stadium to
Sathorn Bridge
> 23 stations, spaced at distances
of 600m to 1,400 m
> a depot with stabling yard and
workshop
> and an administration building
with control centre
Space-saving Construction
in Cramped Urban Conditions:
12m above Grade
Trains operate on dual tracks directly
fixed to concrete plinths carried on a
9m-wide viaduct. Concrete columns
rising approximately 12m above the
roadway median support the single-box
viaduct girders.
Piled foundations extend some 50m
underground. This well-proven construc-
tion technique is particularly suited to
the difficult site conditions and the re-
quirement to save valuable space in the
main city centres of Bangkok.
Link with the Entire Railway
System – and with the Future
Each three-car train carries up to 1,100
passengers. Independent ridership stu-
dies show that the BTS, running three-car
or six-car units from 5a.m. to 12p.m.
every day, attracts approximately
650,000 passengers daily and more than
triples the average travel speed to 35kph.
In the start-up phase, the transport ca-
pacity is 22,500 passengers per hour and
per direction (pphpd) for the Sukhumvit
Line at a service interval of 2 minutes in
peak periods. For the Silom Line, the
transport capacity is 13,500pphpd.The
BTS will be linked with the other railway
systems being built in Bangkok.
The Cars: Comfortable and Safe
All cars are air-conditioned and connected
by means of intercar gangways. Passen-
gers enjoy the feeling of all-around com-
fort, safe and quick transport.
The Environmental Benefits
The BTS is an environmentally sound
solution for a congested city:
> it reduces Bangkok’s precious space
and road surface only minimally
> all cars are powered by electric motors
fed by an electrified third rail, thus
avoiding air pollution
> it incorporates a signalling system
that allows automatic operation of
the trains at optimum performance
and therefore energy-efficient driving
conditions
> power is recovered
from braking

BTS – The Success Story
The concession for the BTS was awarded
to Bangkok Mass Transit System Public
Company Ltd.(BTSC) on April 9,1992.
The turnkey construction contract for the
Sukhumvit and Silom Lines was awarded
to the Siemens-Italian Thai Consortium
on July 4, 1995. Siemens, as leader of
the consortium, was responsible for the
E&M works including system maintenance
during the first five years and system
performance. Italian Thai, responsible
for design and construction of the civil
works, is one of the biggest construction
companies in Thailand.
Sound Financing Concept
BMA recognised that it is no longer the
role of governments to fund infrastructure
projects. Instead, the Siam Commercial
Bank, the German Kreditanstalt für Wieder-
aufbau (Reconstruction Loan Corporation)
and the IFC ensured the sound financing
of the project in terms of cash flow and
capital structure on a limited recourse
basis. With the start of commercial oper-
ation, BTSC derives all revenue from oper-
ation of the two lines over a 30-year period.
During the first five years of operation,
Siemens remains responsible for main-
tenance of the system. When the 30-year
concession ends, all the equipment be-
comes the property of BMA as part of a so-
called BOT (Build-Operate-Transfer) model.
Smooth Implementation
The participation of only two companies
in this consortium and the installation of
the contractors’ and customer’s project
management at one location in Bangkok
made a major contribution towards
smooth implementation. Italian Thai em-
ployed an average of 10,000 construction
personnel in Bangkok for design and con-
struction of the viaduct, stations, depot,
administration building and utility diver-
sions at any given time and mostly at
night so as not to obstruct daytime traffic.
Siemens as consortium leader was
responsible for the design, manufactur-
ing, installation and commissioning of
all electrical and mechanical equipment:
>Signalling
>Telecommunications
>Automatic fare collection
>Power supply system
>Scada system
>Third rail system
>Trackwork
>Workshop equipment
>Civil engineering services
>Rolling stock
Most of the design and manufacturing
activities took place in Europe. Before
shipment, the equipment went through
factory tests to ensure a smooth installa-
tion and commissioning process. The
trains were tested at Siemens’ test centre
at Wegberg-Wildenrath, Germany, thus
reducing testing time in Bangkok.
Siemens also performed the planning
and execution of training for the custo-
mer’s operations staff and finally the
overall system tests.
Altogether, it took the consortium mere-
ly four and a half years to implement this
turnkey project – from contract signature
to the start of BTS operations.
Bangkok Can Breathe Again
With the new millennium, BTS offers its
passengers speed and reliability, proving
to be a very attractive alternative to road
travel. The Sukhumvit and Silom Lines
ensure that Bangkok can breathe again.
