The color on the Turbine Car was actually a solid, non-metallic color. It appeared to be overcoated with a clear glosscaot containing a gold/copper "mist". Its a difficult color to describe, and damn-near impossible to duplicate. There's a pretty good depiction of the color at:

Great looking job on that on, by the way. It really captures the feel of the original.
