I'm still hoping for a period appropriate tender, especially if they can put sound in it.
But what I would really like to see is a more modern 4-6-0 such as the B&O B-18, which did start with some flat-looking low tenders, but ended up with some more modern looking tenders, although obviously not the USRA versions.
And, then there are the B&O class D-30 0-6-0 switchers that had USRA tenders, not the slope backs that Bachmann puts on theirs.
