Interesting article- Y-6 differences

[NW Mailing List]

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.
