Interesting Dope
On Essex J0unt

c. z. Beach, Arizona manager for
the PennZoil company, gives some
very interesting side lights on the
performance of the new Santa Fe
inspection car. which caused 30 much
comment and excitement when 1t APP
peared on the tracks OF our local
street railway, after making trial
run from Los Angeles. Naturally
said Mr.. Beach. many comments
were made and many questions asked
why this particular type of car had
been selected?" "Why Pennzoil had
been selected for use in the motor?"
How did the motor and lubricant
PERFORM To give some very aston
ishing facts and figures. Mr.. Beach
went into many details furnished him
by the PennZoil company OF Los An
geles. and told how fabrication played
such an important part in the test.
The Santa Fe officials selected the
Essex coach. which is officially
known as SX-100 Special, in their
endeavor to promote greater eff
cheney, and to provide a more rapid
and flexible means for inspection
The operating of an inspection train
consisting of locomotive, coaches
and a crew Of five men, was both
cumbersome and top heavy with ex-
pense. The conclusion reached by
the officials was, that If depend
able, durable and efficient type OF
automobile inspection car could be
developed, a more flexible means or
transportation could be provided,
which would lessen the time lost in
making side tracks, and speed up the
between station runs.
A few minor changes were made
in the regular Essex coach model, in
order to fit the particular condition
of railway work. Twenty inch
flanRed railway type OF wheels were
substituted for the regular wheel
equipment. the front axle and wheels
made rigid, and the regular railway
equipment of signals, lights and
whistle added The crank case was
filled with five quarts of PennZoil
because this lubricant could be de-
pended upon TO endure and stand up
under the heavy service condition OF
high speed. heavy duty and contin-
uous running. The consumptiop OF
Iubricating oil for the entire trip
amounted to a fraction over seven
quarts. or at the rate OF I1o.S miles
per gallon of oil. The time limit de-
manded running at better than ex-
press speed in order TO prevent
blocking the traffic. Some concep-
ton of the heavy service demand
can be gained when you consider that
speeds varying from so to 55 miles an
hour were common. On one stretch
of track between Wickenburg and
Asnfork, 81 miles per hour was reg
istered. The high average speed or
40.3 miles per hour on the run TO
Phoenix. and s7.3 miles per hour
from Phoenix 20 Los Angeles, via the
Grand Canyon was maintained IN
spite OF the heavy grades and loss OF
time in side tracking.
on this entire trip covering 1,S4s.z
miles, over three railway divisions,
not q single mechanical adjustment
was made. Had there been the
slightest break in the fubricating
film or failure of the oil to hold It's
body and piston sealing property the
unusual record OF no mechanical ad-
iustment would not have been pos
sible. q,
The even. smooth way in which the
grades were negotiated, the even
running motor and high speeds at
tained were due to the quality or the
lubricant which reduced friction,
kept the bearings cool. and did away
with mechanical troubles and ad-
justments.
