Things I like here:
- RK Imperial Niagara
- RK Imperial Modern Auto Racks
The Niagara almost seems like a no-brainer to me. It would sell well. Same with an RK modern auto-rack. The scale versions are two long for most modest layouts - something that would fit two levels of 2 or 3 1:43 cars on each level would be fantastic. I'd be in for a fleet.
I would add:
- RK Imperial T1/S1: Lots of people out there with smaller radius curves that would LOVE to roll one of these! I think they'd sell a ton of them. The Imperial PRR Turbine seems to have sold well over the years; why not a T1?
- Articulated well cars in RK or Premier. I absolutely love the N-scale Kato sets I have. Intermodal is challenging to model in O gauge and have it look good, but this would help.
- A RK Imperial Veranda Turbine? Not sure how well this would sell - I'd sure like to have one....
- As PS3 RK K-4S reissue - I think we're due for these, actually.
- More containers for RK and Premier. Especially in RK. They are getting better about this, but I'd still like to see more prototypical options. I'd love to replace my ho-hum NS/BNSF containers with a little Hanjin/Hyundai/EMP/J.B. Hunt/Swift/etc. color.
- I keep hoping for a PS3 reissue of the RK Imperial SD70ACe heritage models. Not new, per-se, but I missed out on a MOPAC/UP Screaming Eagle and I want one !
OK, the last two were a little weak. But I do think that Niagara's and T-1's in RK Imperial would really sell well.
