Q & A

3. Greece: Preparing for Athens 2004
Public Transport Services: Considered as the most crucial for the success of Olympic Games
Major Infrastructure Works and Transport Systems:
METRO
ΤΡΑΜ
Inter-city Rail
Athens International Airport
Intercity Motorway
Rio-Antirio Bridge

4. TRAM: A modern light rail transport system for Athens
Link Athens City centre with the southern coastal suburbs
Will alleviate traffic congestion and cater for transport needs during the 2004 Olympic Games.
Thirty-five new tram cars will transport up to 2,500 passengers along the lines during peak hour.
Two tram lines
Total 30km of rail tracks
48 Stop points
An Operation Control Center
One Depot
TETRA network

5. Project Overview Construction started in 2002
To be Operational by May 2004
TETRA for radio communication services between Vehicles and OCC
N-TOPOS provides On-Board Control & Communications Equipment and Telematic Supervision System.

6. Communication Requirements
PMR Services : TETRA Voice & Data
(Automatic Vehicle Management, Public Address, Passenger Information, Emergency Call System, Driver’s MMI)
High Speed Fiber Optic Network: Gigabit Ethernet
(CCTV, PIS, AFC, IP telephony, SCADA)
