I have noticed almost everybody from N thru O who built the Santa Fe blue goose also built passenger cars in the same colors that never existed.
Although most look very nice I just don't understand why the builders made them.
There is only one reason, they must have been asked for and they must have sold.
It does make for a pretty train though.
The matching cars for that train does look nice. Having two completed set of the blue goose I would say it look amazing with the rivarossi a and b set of cars. When these cars were made I think they just trying to make as many streamlined equipment from as many railroads as they can.
