N&W in 1903 -- Leviathans

[NW Mailing List]

I guess that it was done by shifting somehow the central pivot point  
of the equalizing lever connecting the drivers' suspension with the  
pilot truck suspension.  This pivot point would be under the cylinder  
saddle.  I've not heard of such a thing in 4-4-2s (which could sure  
use it!), but I've heard of weight transfer devices on some non-North  
American locos.

could this be the water shifting back in the boiler?  LOL  when  
braking, the water would shift back over the 'smaller wheels.'

N. & W. TO HAVE FASTEST TRAIN IN THE SOUTH
------
N. & W. WILL HAVE SIX LEVIATHONS (sic)
------
New Atlantic Type of Engines Have Been Ordered
------
     The Norfolk and Western railway will shortly have six new  
engines of the Atlantic type in operation.  These engines are to be  
used to reduce the schedule between Richmond and Norfolk.
     The most distinctive features of these racers are the large fire  
surface and an automatic arrangement whereby, when pulling a heavy  
train up grade, or in starting, an additional 10,000 pounds of weight  
is placed on the drive wheels, thus preventing to a large extent the  
slipping that is usually experienced in such instances.  When running  
on the level or in coasting, the additional weight is thrown from the  
drivers on to the smaller front wheels, thereby obtaining a higher  
speed.
     The Baltimore & Ohio and the Chesapeake & Ohio railroads, which  
cross both the Blue Ridge and Alleghany mountains in reaching the  
West, use these locomotives for fast passenger work, both systems  
having in one or two instances grades of nearly 2 per cent, or 100  
feet to a mile.  This is especially true of North mountain, in the  
Alleghany range, on the Chesapeake & Ohio, where for ten miles there  
is a grade of 94 feet.  Formally passenger trains of eight or nine  
cars were double headed for such ascents, but it is a frequent  
occurrence for an Atlantic type locomotive to pull nine cars over the  
mountain on schedule time.
     The Atlantic type of engine is regarded as a luxury by many  
railroad men.  The number of these locomotives now in commission on  
the Eastern railroads is:  The New York Central, 155; Pennsylvania,  
103; Baltimore and Ohio, 60 [?? blurred, best estimate]; Chesapeake  
and Ohio, 25; Norfolk and Western, 6.
     Until the Chesapeake and Ohio gave its first order about  
eighteen months ago for ten of these monsters, the operation of such  
locomotives was confined to the lines north of the Potomac and Ohio  
rivers.  The Norfolk and Western has now fallen into line with an  
order for six of the Atlantic type.

[ It is interesting that locomotives produced in New Jersey were  
readied in Kenova, WV for service between Norfolk and Richmond.   
Also, can anyone explain how the mechanism worked to put an extra  
10,000 pounds on the drivers as claimed in the article?]
