Personally I stick with 4 wheel trucks on the RailKing stuff because the 6 wheel trucks are blind on the inner pairs. Hearing those click on and off the rails drives me nuts.
I wonder if they could do an AS-616 as a B-B to get close to a DRS-4-4-1500?
While I don’t think the PRSL ever rostered any VO-1000s the PRR did, so it’s not out of the realm of possibilities, and at least it’s a Baldwin.
P.S. I guess this is what you envisioned?
