Hi Matt,
Rumor is that USAT is starting production on a number of engines. The S4, possibly the nw2, and some of the geeps. Also the larger SDs.
The issue I heard a few years back was USAT didn’t own their molds and Kader did, who owns Bachmann and now the Aristo IP. So they were beholden to what Kader would run for them, when, and at what qtys. Now they supposedly bought back all their molds, found a new manufacturer and are kicking off production again! And production on the new F7 streamliners.
Again all rumors and until you see new Engines anything can change. However you can back order a number of engines and road names which use to say sold out on the Charles Ro site. So there is hope.
