boiler for N&W 2300, "Jawn Henry"

[NW Mailing List]

The boiler used for Jawn Henry was vastly different than the ones used 
for C&O's 'Chessie' turbines.  The JH boiler resembled industrial or 
marine water tube boilers; more or less cubical in shape.  The boiler 
for the C&O locos was pure railroad, much the size and proportions of 
those for the 2-6-6-6's.  Other locos which tried the fire tube idea 
limited the tubes to the firebox walls; the remainder of their boilers 
were conventional with flues, etc.

Responding to the query and comments on the Jawn Henry (#2300) water 
tube boiler, I want to note that in the 37th Edition of Steam, the 
annual Babcock and Wilcox publication on that subject published in 
1955, there is a photo of the boiler that would be installed in the 
2300 set up for operational testing on a shop floor. It can be found on 
page 26-5. Its only resemblance to a locomotive in that image is 
strictly in terms of proportions and scale, and accomodation to the 
carbody style of the diesel-electric locomotives of the period seems to 
have been in the minds of its designers from inception. 
 
This seems to differ from some other designs for water tube boilers in 
locomotives, but consistent with the design used by the C&O "Chessie" 
project of roughly the same time. 
 
Sorry to have taken as much time in looking this up and posting.
