The above figures on weight nd capac-
ity of narrow-gauge freight cars may ap.
pear somewhat surprising, but their cor.
rec:ness has been proven by actual use on
the Cairo and st. Louis road, The less
weight and strength Of parts required in
the nsrrow.gauge freight car, 10 sustain u
| given load, Is attributable 10 three facts
q diminished ovefbsng ai tho sides, lie,
area over which the load is distributed
and the greater proportion Of i: carried
within the bearing points. OF course ;hi:
would 10. apply in the case OF bulky
| freight, where the full load cannot hC
placed on the threc-feoi car, but in the
shipment Of coal, iron ore corn. etc, all
this advantage is available in favor OF the
narrow-gauge road.

On the three fee; gauge are eight fee,
shorter, two feet nine inches narrower.
one foot two inches lower from sill to too.
sud stands one foo. one inch nearer the
rail than the wide gauge coach, and from
the rail 30 the top Of the car the narrow
| coach is three feet lower than tho wide
gauge coach. Thus il is shown tina. 60 fer
as stability Of equilibrium Is concerned
the narrow.guago car is really the safer.
DEAD WEIGHT.
Another advantage which the narrow
gauge road has over the wile-gsuge is,
tina; they 10 no: carry 50 much dead
weight. 1t is admitted that every ton Of
weight drawn over o railway above the
minimum absolutely necessary for trans
portaiioE Of the paying load, results in
this disadvantage;
/. The waste CT steam power.
Injury g both track and rolling
stock by the increased force Of the ham
mering blows cSertcd by trucks and
driving wheels. The standard gauge pas
senger coach empty, hammers tile rail
with force OF $500 pounds on each
wheel, while the uarrow-gaugs wheel
strikes with force OF less than 1000
pounds. This evil shows still more
asains. the wide-ssuce read in q COMPARE
son OF locomotives when the weight re-
CURED TO draw given amour, Of paying
freight is more than double tina. Of the
na.row-gauge, This point will be
noticed further under the head Of locomo-
tiyes.
Recurring to the comparative weigh,
Of empty and loaded cars a. given in tue
above tables the following fact, are de-
ducei
/. The dead weight of q wide gauge
c0ach-3S. 900 pounds divided among
fuy-siN passengers gives Us pound. 10
each passenger. The dead weight Of
narrow gauge coach-lj,gJU pounds d.
yided among thirty-two passengers gives
only 4U9 pounds - esch--a difference Of
2o9 pounds in favor of the narrow gauge.
some three feet cars are bail. to sc-
commodste thirty-siX Passengers, making
the gain Ltty-three pounds more, bat the
comparison j. made between the better
class Of coaches on each gauge.
>. y narrow gauge eight wheeled pas
senger coach with its tall loaI-thif,y-
two passengers weighs about nine tons
less than Gr,,-class, wide gauge coach,
when empty.
