longer trains it will rise to SIT cars per
hour. Thus a 10 per cent. increase of
cost will add more than 40 per cent. to the
capacity to serve the public. Not only
that. but the zone of territory served and
contributing traffic to the line will be
widened from 30 to 80 per cent. at the
same time.
The stations and ticket control will
cost more: but allowing for this. for
charges on additional equipment, for
charges on the additional construction
cost. in the forty-nine years of the pro-
posed Interborough contract, by con-
servative computation. the city's return
from the property will be from one hum
dred to one hundred and thirty millions
Of dollars greater than without the en-
largement. or enough to build another
subway. More important even than
the money return will be the larger and
more comfortable service the public's
road can give the public.
By setting about enlargement Of the
existing subway at an early date longer
trains may be run over that road two or
three years before the new lines are opened
affording much needed and already too
long delayed relief from present conges-
tion.
Lengthening the platforms OF the exist
ing lines O thGt longer trains may be run
would prepare the wey for similar
enlargement OF the new parts of the
Interborough system. which will otherwise
be impracticable. as old and new lines
are to be operated on the same standards
To enlarge the new lines would cost
little. probably only a third es much al
the more difficult task Of expanding the
old roads. At the outset il would be
necessary only to make excavation for
the longer stations as traffice incres ses

the longer stations and open more end

provided for in the design. The great ,r
