The challenge
The Indonesian capital of Jakarta has outgrown its socio-economic area into its surrounding suburbs of Jabotabek, a nickname
abbreviating the cities of Jakarta - Bogor - Tangerang - Bekasi.
Population surge and accelerated pace of urbanization in the
conurbation resulted in chronic traffic and environmental problems. In 1980, the Indonesian authorities launched a large scale
program to integrate the existing railway network into a modernized commuter railway system. It consisted of rehabilitating and
modernizing, as well as electrifying the existing commuter lines
in the Jabotabek area.
The Jabotabek railway system consists of circular routes encompassing the Central Business District of Jakarta (Central line,
Eastern line, Western line) and radial routes extending to the
suburban areas (eastbound Bekasi line, southbound Bogor line
and Nambo line, westbound Tangerang line and Serpong line; and
Tanjungpriok line in the North).
The infrastructure is owned and managed by the government as
the railway operator, while train operations are managed by PT
Kereta Api Indonesia.
Both intercity and commuter trains operate in the network. Most
intercity trains run eastward along the Central, Eastern, Western
and Bekasi lines and a few westward along the Western and Serpong lines. Commuter trains mainly operate as suburban services
between suburban residential areas and DKI Jakarta.
Since the over-the-decade, rehabilitation and modernization
works have been implemented to the existing network, the total
length reaches 170.2 km. Most sections are now double-tracked
and electrified to 1,500 V. Over the last 10 years the project
wields its effects in achieving a rapid increase in passenger volumes, in parallel with the increase of the number of trains made
possible by double tracking, improved signalling and station facilities, and a larger fleet of EMUs.
With its roads and railways networks developed historically along
a North-South axis of topographical layout, the city’s metropolitan development plan, whilst broadening its concentric growth
away from Jakarta city center into the surrounding commuter
zones, expands towards an East-West development axis. The
railway network modernization project also sees its effect on

accompanied land use development of large scale housing complexes and industrial estates.
Numerous housing estates were built along the eastbound Serpong and Tangerang lines, forming clusters of commuters who
are heavy users of the system.
Future development also aims to construct a new mass transit
railway on a North-South corridor in the center of Jakarta.
SYSTRA has been among the key players in the rehabilitation and
modernization projects of the Serpong line and the Tangerang
line.
serpong line
Serpong line is part of the Western corridor of Jabotabek. Its
conglomeration of 5 housing estates along this line (namely Permata Hijau, Simpruk, Bumi Bintaro Permai, Bintaro Jaya and Bumi
Serpong Damai (BSD) makes it a commuter service line.
Since 1990, the single track improvement project had been carried out to Serpong track which consisted of track improvement,
betterment of train stations emplacement, electrification and signalling system. Since the improvements were completed in 1998,
the modernized line provides a transportation capacity of 15,900
passengers per direction for two peak hours, with a headway of
17 minutes using two train sets of eight cars per direction. Maximum speed is 80 km/h. At present, the existing Serpongline has
the function as mass transit system connecting between urban
and suburban areas.
Future plan aims for a double tracking project providing a short
cut between Palmerah and Karet stations.
Rolling Stock
Both trains hauled by diesel locomotives and the newly equipped
EMUs run on the line. Two executive-class trains using newly locally manufactured (PT.INKA) EMUs operate in the morning from

Track
The former single track is now made up of UIC R54 Rail laid on
re-stressed concrete (PC) sleeper. The track panel modules are
categorized as short welded rail of 100 m length in each module.
Mechanical joint with fishplate connects two track panels. Wooden sleepers are used at the locations of mechanical joint.
The track structure is constructed on geotextile sheet. The geotextile separates the ground soil with the sub-ballast layer or sand layer.

Catenary and Power Supply Utilities
The composition of the catenary system consists of 2 contact
wires of 107 sq. mm, 1 messenger wire of 116 sq. mm and 1
feeder wire of 262 sq. mm. Four rectifier substations had been
provided in Karet, Limo, Jurang Mangu and Serpong. Each rectifier
substation delivers 1,500 V DC traction power through a transformer rectifier set with 3,000 KW power.
Signalling
The Serpong Line now uses Solid State Interlocking (SSI) to control and monitor the signalling system in stations and Centralised
Train Control (CTC) system to supervise operation of trains along
the line. The existing route is equipped throughout with colour
light signals and power operated point machines.
Stations
The line is about 23 km long, serving Tanah Abang to Serpong
stations at the end through four crossing stations: Palmerah, Kebayoran, Pondok Ranji and Sudimara and three passing stations:
Pondok Bitung, Jurang Mangu, Rawa Buntu.

The system combines the operation of commuting trains and
other traffic as freight and long distance trains.
tangerang line
The Tangerang line links DKI Jakarta city center westward to Tangerang city. Traffic congestions between Jakarta and Tangerang
were acute especially on the main roads such as Jalan Dan Mogot.
In the surrounding area of Tangerang line, large-scale housing
and industrial estates were developed around Pesing stations,
two well developed housing estates on the south side of the line
namely Green Garden and Taman Ratu; and southward of Rawa
buaya station other housing estates namely Taman Semanan
Indah and Kosambi Baru estates.
The detail design for Tangerang line improvement had been carried out by SYSTRA in 1988. The Tangerang line extends from
Duri, where it is connected to the Western line, to the west.
It is about 20 km long.
The improvement plan of this line is divided in two phases, NSTO
(New Single Track Operation) as the first phase and the Tangerang
line modernization for the double track operation as the second
phase.

Traffic
During 2 peak hours, the headway is 21 minutes from Tangerang
to Duri. The transport capacity given by trains of 8 diesel rail cars
is around 13,000 passengers/hour in each direction.
Signalling and Telecommunications
In Duri, the new electronic signal box controls the access and
exit routes between Tangerang single track and the 2 terminal
tracks of the terminal. Connections with the Western line are
using specific operation rules. The current mechanical signal box
remains for the Western line until modernization is done.
The Centralized Traffic Supervision is located in Manggarai and
a traffic controller is in charge of telecommunications and data
transmission links.
Trains are equipped with radio telephone sets (receiver-transmitter) in each driving cab. A direct telephone with the stations
enables communications along the line.
Stations
There are 3 types of stations:
Duri and Tangerang are the terminal stations for the commuter
service,
the passing stations are Grogol, Pesing, New Stations 1, Bojong
Indah, Rawa Buaya, Kalideres, Poris, Batuceper and New Station,
the crossing stations are Pesing, Rawa Buaya and Poris.
within the scope of works carried out on the Serpong line
(1988-1995) and then on the Tangerang line (1995-1999):
• supervision of the manufacturing of components and equipment for track, electrification, signalling, telecommunications,
operation aid-systems,
• training, tests and commissioning.

SYSTRA’s Role
SYSTRA contributed to the implementation of this project from
the very beginning. After a first feasibility study on the reorganization of the various lines of the network in 1982 up to 1983,
the following SYSTRA services were provided:
design engineering for rehabilitation and modernization of
three lines of the network (Western, Serpong and Tangerang
lines) over a total length of 60 km (1986-1988). At the same
time, training of Indonesian staff to the techniques for manage
ment and operation of a railway network,
