Tim, they were very easy to setup, easy to insert containers, stable with double loads, pulled with long loads behind and with both AZL and MTL couplers.

Well, I don't know if Micro-Trains simply didn't announce this at the NTS, or if it was missed (or maybe I just missed the announcement somewhere?) but this month Micro-Trains announced their previously-released-in-N "Tie Train" set with UP-heritage gondolas. https://www.micro-trains.com/index.php?route=product/product&product_id=3366 I think this is an exciting release. Yes, it isn't new freight car tooling per se, but the crane is new and possibly the loads, and an opportunity to get some nicely weathered gons is nice too.
