With all of this recent talk about the 'new' Big Boy', I just had to go back to comparisons among the big steam engines,...particularly the C&O Allegheny.

I found this VERY interesting comparison,...plus a number of follow-on postings.

Several years ago I acquired this small steam engine from an estate sale here in FL. What I noticed about it right away was all the nice detail that had been added to it. The gentleman had put some very nice workmanship into it.

It doesn't run at the moment, but I'll figure that out once I get my layout up and running. It's quite a heavy little loco, so its tractive capability should be quite good.

It has no markings as to its origin, so I was wondering if someone might recognize what it started out life as??

I am embarrassed  to admit that even after 20 years or so of model railroading, I don’t know anything about wheel sizes on rolling stock.  Is it right to even ask “what size wheels were used on Bettendorf trucks?”, or were all the standard wheel sizes used?  Or only a lesser number of all those available at that time?  

I guess I could really use a primer on wheel sizes on freight rolling stock.  

Thanks!

I need to find two sets of Athearn PA1 Locomotive Powered Trucks.  So far I can only find "dummy" Trucks.  So can I use them and convert them into powered Trucks?  If so what parts need to be replaced?  Thanks
