pumps on K1

[NW Mailing List]

Mike:
 
Try Walthers  Part # 585-31265 for the feedwater heater and either Walthers 
 Part # 190-334 or Walthers  Part # 585-3449 for the cross-compound air  
compressors.
 
"What  do they do?"  "Readers' Digest summary", the feedwater heater uses 
exhaust  steam to pre-heat the water before it's fed to the boiler, thus 
improving  efficiency by reducing the amount of coal that would otherwise have 
to be burned  to heat the water to its boiling point; the air compressors are 
the source of  the compressed air for the air brake system.
 
If  you want the long-winded explanation, I suggest starting with “How  a 
Steam Locomotive Works”; Parker, Karen; TLC Publishing, 2008; it's available  
from the NWHS Commissary.

That’s a Worthington BL feedwater heater.  Should be available from  detail 
parts manufacturers.  The pumps on the right side are two  cross-compound 
air pumps.  No kin.

What does the large flat device on the fireman side of a K-1 do?

Do you know where to get an HO scale one?  There are two smaller  pumps (or 
whatever) on the engineers side.
What do they do?
 
Thank you,
Mike Shockley
