The morning Astorian. [volume] (Astoria, Oregon) 1899-1930, 1904-03-09

Transportation exhibits at the Louis
lana Purchase exposition are being in
stalled In three seperate places. First,
within the walls Of the palace in the
main picture that bears the name Of
this classification; second. in an out
door space adjacent to this building:
third, on the aerial concourse. which is
situated In the west OF the grounds.
Fifteen and six-tenths acres Of
ground are covered by the Palace OF
Transportation, which is 1900 feet long
by SIS feet wide. Within the walls are
Ave miles OF railroad tracks, on which
exhibits are being brought in on their
own wheels.
On terraces without are 1900 ad-
ditional feet Of track, maintained for
the supplemental display.
The balloon concourse Ii I,200 feet
long by 600 feet wide 1t Is protected
on two sides by dormitories Of Wash
ington university, which with other
college buildings have become part
OF the fair, and on the third side by a
temporary wind brake. Thus the aer-
ial craft will be protected until well
up on their voyages. AT the eastern
end Of the concourse are balloon stables,
where repairs can be made and where
gas will be supplied.
From all over the earth exhibits are
coming for this interesting display and
they include everything known In the
world of transportation-from the baby
push-cart TO the mogul locomotive:
from the submarine to the Santos Du-
mont OF latest design.
OF the railroads the Pennsylvania
and the Baltimore and Ohio win make
the most elaborate displays and they
win be distinctly different. That Of the
former company is in the nature OF Q
giant test OF power as applied to trans
| portati0n today. that of the latter Il
historical in character. While each
display appeals TO the visitor. they do
so In q different manner. the Pennsyl-
vania exhibit attracting the practical
mid and the Baltimore and Ohio the
lover of romance.
For the first time In the history OF
| the world a iocomotime testing labor
| atory will be thrown open to all comers
such is the exhibit made by the PEN
nsylvanIa company. In this depart
| ment II VIII be possible to measure 7
pound the pulling power OF any iror
horse OF Ahe rails, while under full head
| OF steam. The mechanism that makes
this possible reminds one OF the char
lot race in Ben Hur. where the We
hicles are apparently moving forward
but in fact are stationary. In the test
ing laboratory the locomotive Is run
upon a system OF cog wheels which
move in opposite direction to the driv-
ers. and the lever is then gradually pull
led omen. even as il is when a train Is
being started. Then faster and faster
move the cogs beneath, until their
speed is the representation of GER
tain number of thousand tons-and
then the true test begins, for the re-
sidual power OF the locomotive is felt
upon steer cables that connect with a
dvnainometer which has limit of 81
500 pounds. An Illustration of the
method is that of man using a test
ing machine. A certain resistance
must be overcome before the pointer
commences to swing around the dial;
so in the case of the locomotive, the
resistance of the cog wheel
must be overcome before there is a
strain on the dynamometer.
Tests in this laboratory may be made
by any locomotive builders in the world
and rules have been framed so that all
viii have equal conditions. Thus the
grade Of coal must be the same and the
water of prescribed quality.
The results of these tests will be
published in book form by the Pennsyl-
vania railroad and the work will prob
ably become a classic in the literature
pertaining to transportation.
Mark the contrast in the Baltimore
and ohio exhibit, which breathes of the
entire life of railroad transportation.

unnisi,a mariner On the O1ea that the
