I shouldn't say this, but ROW equipment - brass locos, plastic Weaver-like cars (no experience with track, signals, switches) - is under-appreciated. Unusual designs - RK-like design, but scale-sized , per the 2-8-8-0's and others; interesting; their PRR T-1 is visually compromised (and articulated!), but has a charm all its own - it'll practically turn in its own length, and runs well.
My ROW pieces appear well-made. I believe that Ajin built them (the brass); Ajin made/makes a lot of 2-rail items.
(FWIW: I have read here(?) that Ajin, as opposed to Lionel's "usual builder", whoever that is - also built the Lionel NYC Niagara. Um. Maybe a bad day? Ajin is Korean, though I don't know if the construction is done there.)
