Athearn has announced for a July 2017 delivery the Frisco open tri-level with three numbers: RTTX 910672, 912317, and 930997. Cost is $54.98. Looks like more good news for Frisco modelers.
I've got my eye on these tri-levels. Delivery date is now listed as late September 2017 btw. I've also got one of the Frisco Genesis Bi-levels along with the Frisco ExactRail Vert-a-pacs.
