cost due to gravity

This statement is questionable: "The cost of building such a structure compared to earth is greatly reduced due to the 1/6 Gravity" Building infrastructure on the Moon will be extremely expensive compared to Earth. 1/6 gravity helps a little, but does not make it cheaper than Earth. Please reword this sentence. thanks.Charles F. Radley 14:14, 10 March 2007 (PST)

Restructure of Bulk/cargo/passenger and addition of new section

I've tried to restructure the proposed progression from bulk to passenger and add a section on types, but I still find the organizational structure of this article to be unsatisfactory. -- Strangelv 08:16, 21 September 2007 (UTC)

Railroads on MArs and asteroids

"Mars With such a thin atmosphere and no oxygen, Mars has essentially the same dynamics as the moon only with more gravity (better cornering)."

Don't compare Mars to the Moon. Mars has windblown dust, etc. "More gravity" means more materials to construct the railroad.

"Asteroids All asteroid like objects have a gravitational force insufficient for traditional railways. The modifications necessary are two fold. An upper track must be added like roller coaster to be able to go a reasonable speed without jumping the track. All materials must be securely fastened with either lids or binding clamps."

A railroad is definatly not neccesary on an asteroid. Maybe a tether an pully system between two spacecraft hovering above the surface. I would not really bother attaching something to any asteroid, especially a rubble pile, since it would just float away. T.Neo 07:27, 15 September 2008 (UTC)
