Hello, Donee
That's a good point on the occupancy. In which case, a train uses more fuel /makes more CO2 than a Prius.
On the Cd, so far it looks like I need to lower it a notch

On your Cd question, yea, .025 might be doable. That is the Cd similar to a passenger aircraft such as a 787. The vehicle would need to have some sort of struts down to the track to support it high above the track to avoid compressibilty drag between the track and the body. The struts need to have minimun section area. Kinda like wings.
