The Dubai Metro urban train network
is a major transport infrastructure
development that is already being used
by over 200,000 rail travellers a day.
It carried 10 million passengers in its first six
months of operation and will soon become
the World’s longest fully automated metro
network, surpassing the Vancouver Skytrain
by one kilometre.
Over 60,000m2 of ComFlor® 80 composite
floor decking has been used in 38 stations,
on footbridges, walkways, platforms
and all elevated public areas.

“The Dubai Metro will
soon become the
World’s longest fully
automated metro
network.”

The Dubai Metro is an ultra-modern,
driverless, fully automated metro network in
the United Arab Emirates city of Dubai. It is
the first urban train network in the Arabian
Peninsula.
It carried 10 million passengers in its first six
months of operation and will soon become
the World’s longest fully automated metro
network, surpassing the Vancouver Skytrain
by one kilometre.
Two lines are nearing completion, with
three further lines planned. The Red Line is
now operational and The Green Line is
expected to complete in August 2011. These
first two lines run underground in the city
centre and on elevated viaducts elsewhere.
All trains and stations are air conditioned.
The Red and Green lines will ultimately be
serviced by 35 overground stations, 12
underground, three depots and three car
parks. Each station has been designed to
also serve as mini shopping centre.

There are four themes used in the interiors
of the stations: Earth, Water, Fire and Air.
Earth stations have a tan-brown colour
effects; Water stations are blue-white; Fire
stations are orange-red; Air stations are
green.
Planning of the Dubai Metro began under
the directive of Dubai’s ruler Sheikh
Mohammed bin Rashid Al Maktoum. The
combination of a rapidly-growing
population (expected to reach three million
by 2017) and severe traffic congestion
necessitated the building of an urban rail
system to provide additional public
transportation capacity, relieve motor
traffic, and provide infrastructure for
additional development.
Japanese manufacturer Kinki Sharyo built a
total of 87 five-car trains for the Red and
Green lines. They are designed to carry 643
seated and standing passengers, and
unusually for a mass transit system, the
trains have three classes of accommodation:
Gold Class, Women and Children class, and
regular Silver Class (economy).Trained
wardens accompany passengers to help
with emergencies.

Dubai Metro features no less than 60,000m2
of ComFlor® 80 composite floor decking.
The large corner curvature detail of
ComFlor® 80 provides a very efficient profile.
In conjunction with the higher grade of
steel (450N/mm2), it ensures typical
unpropped spans of 4.2m simply supported.
Spans of 5.0m can be achieved in the
continuous condition.
The achievement of such large spans means
less structural steel usage and
consequential savings in construction costs,
providing more scope for architects and
engineers in their design process.
The innovative profile design provides real
benefits. Central stud placement provides
superb composite action between the
beam and concrete, due to the stud being
positioned exactly in the centre of the
trough. This ensures the correct concrete
cover to the stud and hence, the full design
capacity of the stud is...
