Oh, I dunno. Seems to me that new tooling comes up sufficiently often, now. This doesn't
help if your pet piece hasn't been made - I feel your pain - but we have the new Lionel USRA Heavy Mike (mine will be L&N), the high-nose GP-30 (refreshed tooling - I've ordered
the SOU), some with correct trucks.
The 4-new-articulateds-in-a-catalogue days are over (would you buy them all?). The
O-gauge manufacturers have modeled only a small percentage of, for example, prototype
steam locos; we can hope for more, but at a rational pace.
I don't follow MTH as much as Lionel or the Lionel-pals, but those later Mohawks are
a real achievement (I have the Lima L3b).

Perhaps we should continue to encourage Weaver to keep offering low-volume steamers,
for those of us who want the less-mainstream.
(Again, NC&StL streamstyled 4-8-4's.)

HOWEVER: for the life of me, I cannot recall any O-gauge/scale offering of a waffle-side
(proper name?) gondola. I see them all over the place; common, modern car. But,
if one has been done in plastic/scale, I don't know about it. Why?
