Cars that were used on the trip to Chicago were from the Santa Fe's then current business car fleet. Closest thing to represent them would be Kato Super Chief cars,sleepers and diner. Santa Fe also had some coaches and a full leingth Big Dome Lounge car (Bachmann Model) and I cannot recall if coaches or the dome car were on that train . Kato's Business Car lettered for Santa Fe although a copy of a Burlington car makes a good stand-in. The train that was run to Williams , AZ for the National Railway Historical Society Convention, would be harder to model. I rode on that train which was quite colorful, the cars were owned by members of the American Association Of Private Car Owners and included a PRR. sleeper lounge car, a CZ Dome Coach,three heavyweight cars, sleeper lounge, solarium lounge, business car,former Santa Fe Pleasure Dome lounge car, former N&W coach, former Santa Fe budd coach, a former Rio Grande lunch counter diner,former CP baggage express car used by train crew "Pony Express" which has been used with the steamer before. I'am sure I left several cars out of the consist. I will have to dig out my slides,but the train you want to model is the all Santa Fe consist. Nate Goodman (Nato0. Salt Lake, Utah .
