Regarding the N Scale F89-J's and their tardiness...
It's safe to say that not every project is simple. The N Scale Spine Cars and the F89-J's have easily been our two most complex projects for numerous reasons - mainly, because we want to make them identical to the prototype, per road number. For instance, the F89-J's feature a multitude of era specific details including hitches, bridge plates, risers (wood or steel) and more. Furthermore, of the six announced RTTX road numbers, there are three completely unique paint variations between six numbers - that's something I don't think any other manufacturer is doing and showcases our commitment to quality. The models are currently in production and your patience is appreciated; they'll be worth the wait.
I was just whining since the HO ones shipped already.
In fact, my wallet appreciates the delay.
