A question about scales.....

Michael, wouldn't that be pretty close in length to your Z-scale?  My Z-scale 4-6-2 measures 3-7/8" with tender.  I can't remember the exact ratio, but T is significantly smaller than Z, no? 

T scale is 1:450, and is for better eyes than mine  

At 3 1/2" in T scale the ornament scales out at almost the same length as Big Boy; 132 ft. Not too far off, but somewhere between Z scale and N scale. If the NYC Hudsons are about 95-100 ft long with tender, say 65 ft for the locomotive? Then the ornament is about 1:222 or so?

Thanks to you both. My understanding is that T is about half of Z. A side-by-side measurement shows that the Hallmark ornament is about 70% of so of the Z scale. Therefore it is too long. WITHOUT the tender however, and I don't know that I want to do that, it is just exactly half the size of the Z scale with tender.

Now all you have to do is motorize it and lay some rail.

Glad to be of at least some minimal assistance.  I love your focus of collecting NYC steamers in all scales available.  I have done the same with ATSF streamlined diesels, but haven't been able to score a 'T' one as of yet.
