APPITRACK PROJECTS

Infrastructure - Track Works - Page 8

APPITRACK Modern technology for track laying

Step 1 : Slipformed concrete

Step 2 : Fasteners insertion

Step 3 : Completed slab with fasteners

Step 4 : Completed track

Step 5 : Finished track

APPITRACK - Automatic Pin & Plate Inserter for TRACK

> Accelerates construction => up to 6 times less than the traditional method

> Preserves the environment and reduces carbon emission

> Reduces civil works, concrete volumes and dust> Reduces noise and disturbances> Ensures cost effective & high quality track

construction due to the machine’s high precision> Less painful operations and 3 to 4 times less

accident hazards

Average daily speed in linear meter : 150 lm for tram (maximum 403 lm) 400 lm for metro

> A fully mechanized installation method developped by Alstom

APPITRACK Some project data

> JERUSALEM PROJECT – Completed

> ALGIERS PROJECT – As of 28th February 2011

> REIMS PROJECT – Completed

> CLEO PROJECT – As of 28th February 2011

> Installation program can be more aggressive to increase Appitrack usage

APPITRACK Metro – A new solution

> Tests successfully done in Singapore (length of pumping > 400m)

> Control of concrete consistency test successfully done in Singapore for slipforming

Appitrack (optimised) versus typical project (excluding depot) - 12,2 %

> Optimised planning

> Optimised cross section (less concrete)

> No Stray Current Corrosion Control (to be estimated)

> Comparable perimeter as a new typical project

> Insertion tests done with rebars

> Successful Pumping Tests (> 400 m)

> Development of fastening systems with approved suppliers

> Free for tender in November 2010

> 30 potential projects within 4 years

HAS (High Attenuation Sleeper) : An alternative to floating slab track

Infrastructure - Track Works - Page 13

HAS - High Attenuation Sleeper An alternative to floating slab track

Fastening system according

to customer choice

Concrete sleeper Rigid plastic hull

Holes for conductor rail support

Polyurethane seal

> Use of a rigid hull• Reduction of stiffness (no vertical friction between sleeper and hull)• Friendly maintenance (sleeper easily clipped in the hull)

> Concept of track with sleepers• Friendly construction (standard production rate without discontinuity)• Reduction of tunnels diameter (FST systems being thicker)

> Concept of track with sleepers• Attenuation higher than 20dB at 63Hz

Infrastructure - Track Works - Page 14

Advantages of HAS over FST

> Less concrete (optimisation of the cross section)

> Less manhours required for installation

> Same method than rest of the line

> No stress on the linear planning of works

> Adjustable to specific Rolling stock data

> Friendly Maintenance

HATT : High Attenuation Tram Track

Infrastructure - Track Works - Page 16

HATT – High Attenuation Tram Track

> Preserve neighbourhood comfort• Attenuation over 10 dB• Urban insertion

> Reduce floating slab track quantity• Reduction of more than 25%

of the trackworks costs• Reduction of worksites costs• Reduction of interfaces (Civil

Works, drainage, APS)

> An existing alternative solution• Proven system: already

installed• « proven use » and « proven

design » system type • Trackworks antivibratil

systems installation • Continuous rail support • Less concrete and no tapis
