Actually, the Y6a had different counterweight shapes than the  Y6b.(crescent 
moons)  The SA was in FRONT of the stack with the heat  exchanger taking up 
more room in the smokebox  which is why THE EXHAUST  NOZZLE was angled slightly 
forward.

Neil:  The  differences between the Y-6a and the Mikes train house model is 
that the Y-6a  is real and the Mike’s Train house model is a LOT  smaller.
 
As to the differences  between a Y-6a and a Y-6b, the Y-6a has the 
Worthington BL-4 feedwater heater  hanging off of the fireman’s side of the locomotive 
with the two air pumps  balancing the load on the engineer’s side.  The big 
difference to the  Y-6b is that the “b” did not use the older Worthington BL but 
used the SA type  behind the smoke stack.  Thus the smoke box got longer than 
the Y-6, Y-6a  and Y-5 class.  Also the smoke stack in the “b” has a forward 
tilt to it  that allows the new equipment to fit inside.  The “b’ hangs an 
air pump  off of either side in a symmetrical manner.  Otherwise the types are  
quite similar except for the different vintages of the 22,000 gallon  tenders.
 
These differences are  covered in Bud Jeffries Giant of Steam book.   
Illustrations of the  ‘tilt’ are shown in the old USRA 2-8-8-2 book by Tom  
Dressler.

Subject: Interesting  article

 
 
I've been a model  railroader for most of my life, but only recently became 
interested in  the Norfolk and Western when I won a Lionel  N&W J at auction 
after lusting after a copy for many years, but price made  it  unobtainable.   
Luckily the item was not advertised, so the  normal vultures that would grab  
up desi\rable model trains at that  auction house never showed up and I had 
very little competition  with my  absentee bid.

 


 
Recently I obtained  a copy of the "Norfolk and Western Magazine" for April,  
1942  and was thrilled to see an article about a "New Locomotive" on page  
166.

 


 
"Completely modern  from stem to stern, the second of 16 new, heavy duty Y-6a 
Mallet freight  locomotives which are being designed and built from the 
ground up by emloyees  at Roanoke shops, was completed and placed  in operation  on 
March  21.  The first Y-6a rolled out of the shops during the later part of  
February.  The remaining 14 are scheduled to come out of the shops at the  
rate of one a month.  These powerful locomotives are of the same design  and 
general dimensions as Y-6's, the main difference being in the  arrangement of the 
wheel bearings.  Both types have eight pairs of drive  wheels, each 57 inches 
in diameter, and a tractive effort of about 152,000  pounds.   In working 
order locomotive and tender weigh 961,500  pounds."

 


 
The article  describes the difference between theY-6 and the Y-6a, and I am 
wondering what  the difference(s) is (are) between the Y-6a and my Mike's Train 
House model of  the Y-6b.

 


 
Thanks for your  help.
