I'm almost done buying the Walthers Great Northern passenger car set, and now need to start thinking about what I'll power it with. I already have a P2K FA A/B/B/A set (the latest ones) and love them, but now I'm looking for a F7 A/B/B/A set. I was looking at the P2K and Genesis, but noticed something... The P2K has silver trucks, and the Genesis has Black...Which one is historically right? The P2K FA set has black trucks, and the cars I have all have black, so why did P2K make silver trucks on the F7's if not correct?? I'm just confused here a bit...
