Now THAT's a lot of wheels!  Excellent find.

And I don't suppose a Decapod wheel set would be a drop-in replacement, huh?

And of course they are sold out.  Does that mean like "gone forever"?

Yeah, wow, I apologize.  Obviously it's a 2-10-4.  I never did well with the new math..... 

And being a 2-10-4, my question has been answered, assuming Bachmann still sells the wheel sets.

Thanks gentlemen,  I will proofread henceforth!

At a swap meet this past weekend I purchased a Bachmann 2-12-4. It tested okay on the straight test track, but when I ran it on my home layout the rear 2 drive wheels fell out of the axle shaft.  I was unable to press them in tight enough to make them stay.  When I checked Bachmann parts, they (of course) don't sell the 2-12-4 anymore.  The iso diagram that is linked is for a 2-10-4.  Will the wheel sets shown in the 2-10-4 diagram replace those on the 2-12-4 I have?
