Well you must have missed the Hallmark units. They were really nice brass units that were proto correct and run really well. Here is a shot of one of the 4-8-4's running on a NTrak show layout pulling an 88 car refer block plus caboose. I have several of these and the ATSF Texas types that all are proto correct and run well. The big problem is the smaller locomotives in ATSF. The Kato Mikado isn't even close to a real ATSF Mike. The Hallmark units show up every now and then both here on TrainBoard Swap Meet and on eBay.
