This was one of those "recapturing the romance of transport" type briefs, to design a dramatic backdrop for a piece of handluggage.
The bladefront contains a bar ahaid of the drive unit, which narrows until wide enough for one person to stand in the front of the nose watching the scenery streak by.
Further sketches which I've yet to scan and render show the single large wheel that each carriage rides on. Each wheel is canted and the whole train is gyrobalanced by the large spinning mass of the wheels for rock-steady stability.
These are the first sketches from the project, hope you get where I coming from!
