The three biggest and strongest pas
| senger locomotives in the whole world
says the Dallas News, will be placed 10
service this fall by the Southern rail-
way. Some idea of their strength may
| be gathered from the fact that each is
fully twice as strong as The celebrate d
| 1899" which belongs to the New
York Central railway and hauls
the Empire State Express, nearly three
| times as strong as the engine which
hauls the Flying Scotchman from Lon
don to Edingburgh, and more than
three times as strong as the engine
which brings the mails from London
| to Ho'ylead. To put the matter in
another way: one of these engines
could haul as much as ten ord mary
elevated railway engines. or four OF the
avera ge passenger locomotives used In
this country.
Coupled with their extraordinary
strength these engines have remark
alb e capacity for high speed. One of
them could pull at the rate of sixty
miles an hour on piece of level,
straight track no less than thirty-three
Pullman cars weighing forty tons
each. Such a train would be more
| than two-fifths of mile long.
The six-cOupled driving wheels OF
these er gipes are each six feet in di-
ameter, and the working ste am pres
sure is 200 pounds to the square inch.
TIE cylinders are of the ordinary sim
| pie type, each twenty-one inches in di-
| ameter with a piston stroke OF twenty
e ght incses. This gives a traciive
| force, or draw-bar pull, OF p 400
pounds, sufficient to haul trainlOad of
4,279 tons, equal to about eigh ty-tive Of
the largest loaded freight cars, at slow
speed on level track. No LOGON olives
now running have so large combined
| cylinder area and steam pressure as
| these new GOliaths.
The fire box is ten feet long and
three and one-hslf feet wide, with to-
tai hes ting surface of lS4 square feet,
while the boiler is five feet two inches
in diameter. with tubes which give a
heating surface of no less than 2,29S
square feet Soft coal, of which about
eight tons will be put on the tender at
starting, will be the fuel.
The total weight of one of these loco
motives without the tender. will be
Iseventy-five tons, of which fifty-eig hit
tons Will rest on the six dr1vip
wheels, the remaining seventeen tons
being carried by the four-wheel truck
in front. Reckoning the bite or grip
on the rail at ouc-fOurth the weight on
the drivers, we get an adhension OF
fourteen and one half tons, or 10000
pounds, which is 1910 pounds more
than the tractive force of the engine,
thus leaving good margi n for wei
weather and slippery rails. The weight
of nineteen and one bird tO,s on each
pair of drivers is also unparalleled IL
tie history of railroads. 70 carry this
weight W tn safety and without heat
ing, the journals of each ankle are
eli ht and one half inches in diameter
by eleven inches 10 length.
The tenders alta ,hed to these engine:
will carry each 1900 gallons Of water
and when loaded to full capacity will
weigh for,y-two and one-half tons
This will bring up the total weight o
engise and tender to 1llt tons.
The obj ct of having such powerful
engines is not so much to make speed
on the level as to maintain it on thu
grades. The maximum grades, o
which there are several from two t.
four miles long, vary from seventy t
Ieighty-two feet to the mile (roughl
