Rapid Railway Network
Tunis
Phase I
Rapid Railway Network Tunis - Phase I Project
The realization of a modern network of urban
rail transport in Grand Tunis, the greater
metropolitan area of Tunis, is part of the
strategic choice for the development of an
efficient public transport system.
The Contractor for the Rapid Railway Network
Phase I project: a consortium of Colas Rail,
Siemens and Somatra-Get;
Total amount of the contract: 145 M€;
Colas Rail's share: 86 M€ share of the
contract includes track, electrification, power
supplies, surveillance and data collection
systems, depot equipment and systems
integration.
Project Key Information
Works:
First phase of Rapid Railway Network includes two lines having a common
central section between Tunis City Barcelone and Saida Manuba stations.
Line D: Tunis City Barcelone to Gobaa.
Line E: Tunis City Barcelone to Sidi Hassine - Bougatfa.
Atelier Depot at Sidi Fathallah.
Outcomes
Meet strong travel demand in key corridors.
Improve traffic flow in order to optimize energy consumption, reduce pollution
and protect public spaces.
Develop a multimodal transport system through the development of multimodal
interchange stations and deterrent parking to encourage drivers to use the
public transport.

Technical Specifications and Design for Overhead Contact Line
Project data:
Line D = 11,5 Km;
Line E = 6,4 Km + Atelier Depot Siddi Fathallah;
Total of 14 railway stations.
ISAF’s Scope:
Technical Specifications and Design for Overhead Contact Line;
Power supply and mounting diagrams for OCL.
Catenary design parameters
Catenary electrified under 2x25 kV 50 Hz;
Catenary-type V200 STI;
V200 STI catenary allows the flow of multi
pantographs trains to the speed 140 km/h up to
200 km/h;
Local conditions (underpass tunnel structure
or Road Bridge, bridge) imposes variation in
height of contact wire on either side of
compliant structures with the requirements of
CCTP and EN 50119;
The supports are HEA or HEB beams made by
hot galvanized steel;
All of the catenary supports and metal
structures is connected through a cable of
protection;
The reliability of the V200 STI catenary keeps
in time the level of quality required for this
project with minimal maintenance.
Catenary equipment
A copper alloy carrier cable (bronze) of 65mm², with
a conductivity of 60% stretched to a tension of 12kN;
A contact wire in Copper 107 mm², with a
conductivity of 98% stretched to a tension of 12kN;
A feeder "negative" aluminum-steel cable 288mm²;
Aerial protection cable made of aluminum-steel
93.3mm²;
Mounting the negative feeder will be suspended
with a glass suspension chain;
Each bracket is constituted by a galvanized steel
tube secured to an insulator. Isolators are fixed to the
brackets by stainless steel brackets
Rigid gantries are installed in turnout areas and in
the stations where fail to establish independent mast
for each track. They consist of two vertical supports
on which connection is made under a self-supporting
beam which are attached chairs for the equipment of
the central pathways.
Main Challenges
The main challenges of this project were determined by the using of three types of
catenary:
For the main lines: Catenary-type V200 STI designed for speed until 200 km/h
used;
For the Depot: Simplified contact line. This solution was imposed due to the
depot configuration, with a large number of lines and ramifications, but also due to
the low costs of construction and maintenance.
For the maintenance and repair workshop: Rigid and retractable catenary. This
solution was used to ensure the parking of the trains with electric traction and by
disconnecting the contact line and by retraction of it ensuring clearances required to
carry out maintenance and repair works safe conditions.
Retractable catenary
HSL Bretagne –

Design for Overhead Contact Line
Project data:
V350STI overhead line type;
60 km of overhead line (analyzed sections);
30 overpasses.
ISAF’s Scope:
Drawing up of OHL mounting plans of interface
with overpasses in compliance with input data
(overpasses plans, layout plans) and characteristics of
V350STI overhead line;
Calculation/verification of insulating distance
between cables (messenger, feeder) and overpasses
components, according with requirements imposed by
technical specification of overhead line type.
Catenary design parameters
Catenary-type V350 STI;
V350 STI catenary allows the flow of trains to the speed up to 320 km/h;
Catenary electrified under 2x25 kV 50 Hz;
The supports are HEA or HEB beams made of hot galvanized steel.
All of the catenary supports and metal structures is connected through a cable of
protection;
Catenary equipment
A copper alloy carrier cable (bronze) of 116 mm², with a conductivity of 60%
stretched to a tension of 20kN;
A contact wire in Copper alloyed 150 mm², with a conductivity of 98% stretched to a
tension of 26kN;
A feeder "negative" aluminum-steel cable 228mm²;
Aerial protection cable made of aluminum-steel 93.3mm²;
Mounting the negative feeder will be suspended with a glass suspension chain.
Main Challenges
A real challenge for our design team was not only to design the catenary for a speed
of 320 km /h but also to design the interfaces of the catenary with the other systems:
civil works, power supply, signaling so that any failure of these systems to not affect
the catenary.
