Quality and resonable replica of the N&W heavy's?

[NW Modeling List]

Gentlemen:

A question to the group at large, how would you rate the Bachmann 
Spectrum Heavy
weight passenger cars, sample Walthers Cat Part # 160-89410, relative to basic
quality of the replication of the Coach, Combine, Diner, and Observation cars,
the color, laydown of the trucks, basic scale and shape of window arrangements,
doors, vents, undercarrige etc... vs the original N&W passenger period
equipment?

Thanks
