CREATION OF A WORLD-CENTRE.
The Terminal Railway Station, lying on the main axis of the plan and
opposite the Civic Centre, is widely accessible. Above ground, it forms the
radiating point of a network of broad avenues, which are to the greatest
extent possible to be kept free from rails. Under ground, it communicates
with sub-stations, placed in immediate connection with all the principal
buildings of the International Centre and with the several quarters of each
zone. Two branches of the main lines of rail which come into the city from
a distance, are carried under ground, to the right and left, as far as the sea.
By these simple lines of communication, none of the heavy traffic need be
carried on above ground. The navigable canal, however, furnishes an addi-
tional mode for the transportation of freight.
The Civic Centre is situated in the first zone, and lies opposite, though
at an adequate distance from the Terminal Railway Station. It is designed
with a great square which will be surrounded by public buildings, such as
the City Hall, the Court of Justice, Post-Office, Public Library, etc. From
this centre spread the principle boulevards upon which hotels, theatres,
concert halls and the largest shops may be built.
To right and left of this business and administrative section, are the
residence quarters, six in number, capable of holding from 100 ooo to
120000 inhabitants each. These are planned according to the checker-
board system, which has been found to be the most convenient since motor
power has superseded animal traction. It will be noted that each section has
its own central square, about which ample space is allotted for those buildings
for the public service which are essential to the needs of the people, such as
the administrative buildings, schools, libraries, conference halls, markets,
theatres, churches, etc. Each quarter is supplied with heat from a central
station on the outskirts of the town, thus avoiding the nuisance of smoke
and gas and greatly facilitating sanitary conditions1. Long, straight avenues,
i. The heating would be combined with the production of the electric current necessary for the
several services of the city. It would be installed in a central station A, capable of furnishing all
the electric energy needed by a population of some 5oo ooo inhabitants. The production would
reach a maximum power estimated at 5oooo k. w. For instance, the station may include 5 turbo
alternators of 8000 k. w. and 4 of 2 5oo k. w. This will permit machinery with economical bea-
rings to function, whatever be the total load of the power house. The turbines are run by conden-
sing water taken from the canal.
High pressure steam will be furnished them by a group of 25 generators of a total heating sur-
face of 22 000 m2 and occupying a space of 3 000 m2. The space needed for the turbines, alternators
and their accessory organs being 1 5oom2, adding the space required for the coal recipient and that
foreseen as necessary for use in the future, the total space required for the Central Station will be
9 000 m2.
The boilers will be provided with economisers for heating the feed water. A certain number of
economisers will be used for heating the water of a circuit, assuring the heating of the industrial
quarters and those inhabited by the workmen. The heating of this circuit will be completed by
the condensation of the exhaust steam from the auxilliary motors of the power-house. The gases
from the boilers may thus be evacuated at a very low temperature, 100 to i5o. The draft will be
mechanically obtained. Deposit chambers will collect the substances contained in the gases in such
manner that only almost pure carbonic acid will be evacuated.
The Central Station A, will furnish the high tension current to the sub-stations 1, 2, 3, 4,
