CTValleyRR: I agree, I've seen a lot of Walthers bashing, mostly about their prices, but they don't deserve it. So their prices are MSRP as willy6 said but I will always pay a little extra for good customer service. I believe good customer service is worth a bit more.
Medina1126: Thanks but it wasn't Northern Light & Power. It was called "Yard Office and Storage Building." It had a few extra parts on the sprues too. I've got the NL&P--N scale. That switchyard was sure painstaking to assemble. You've probably got it in HO. Try it at half that size! BTW, I recently assembled a kit--I forget the manufacturer, the box is gone now, it wasn't Walthers--that had a lot of extra parts on the sprues. The instructions even said that there were a lot of extra parts and the modeler could store them away and use them in future kitbashing projects. That's an interesting concept. Possibly it's cheaper to inject full sprues with similar parts. I guess they'd have to cut parts off the sprues and package them separately for other kits. I dunno. Anyway my "bits and pieces" box is overflowing now.
