BTW, did anyone else notice the different headlight placement for the NS/PRR units vs. CSX and BNSF? Not a big deal, but I thought it was a nice touch. Perhaps this has been the case with the NS Heritage units all along - I suspect based on the PRR version that it was and I just never saw it. Still, having not realized it before, I'm glad they did it in the RK line.
PS; I don't know how they look going around O-31 curves, but they look really nice on O-60 and pretty good on O-54. As good or better than a premier on O-72 IMHO. Between these and the Imperial SD70Ace models, I'm not sure you can do better in semi-scale for the price. They are still large enough to be physically imposing, and the sounds/detail is quite good. When I run them with my RK Imperial steamers, they still provide a good sense of perspective. Compared to the RK K4s, they seem almost impossibly large; next to the RK Challenger, you get the sense of just how big some of the BIG steamers really were.
Yes, it all comes apart when you start stacking them up against scale models, but that's not the point.
As far as the catalog being a disappointment, what were people expecting? The RTR catalogs have never been ground breaking in my experience; a few new things here and there, different paint schemes, etc. is about all I've ever really expected. For someone just jumping in, everything they need is in there at reasonable price points to help them get started- for everyone else, there's April
