Transportation prototypes

I prefer number 2 and 3. From what I can see with number 2 opening more windows to make it look more like a civilian vehicle would be nice.

Although I like number 3 the main problem is that we need the "bus version" so the central part marked by two vertical lines may be longer. The remark "make it look more like a civilian / public transport vehicle" still applies but here I don't really know how to do this without making significant changes (not to the silhouette tho).

Conceptually, in terms of how it would function, I made a blend file which I emailed you. In same blend I show proposed scheme for double rail with flat wheels I feel functionally something may be awfully wrong with what I done but it kind of looks 'stately' as the tilted wheels in #3 really give a 'sports vehicle / concept car' hint that does not reflect proposed function.

Projected capacity 16-24-32 people (not sure) - a 'double length' version could double that capacity (with a qualified junction in middle?).

I think it would be more interesting to have the inside modeled esp. if the doors can open, in some cases K may be able to walk inside e.g. enter at one end drop on a lower roof at the other end, or such.
We can animate this and K could operate some of these using little consoles, maybe even a swipe card.

I don't really think this vehicle would need to negotiate turns, just shoot back and forth over variable (usually short) distances.

Okay so that's what I thought...
