The million a mile figure sounds like they got an estimate from a contractor. Especially in the area around Laws and Independence, I would think it would be possible to construct a mile of usable track at half or even a quarter of that cost - ESPECIALLY if the group can attract rail and other donations or identify sources of "at cost" or recycled materials. A contractor would do this too (especially the latter two items) - at a markup.
Obtaining land rights will be a different story. @#$%& certainly abound. But assuming that there are at least a few supporting abutters, this may not be as bad as you might think.
I understand a volunteer organization already exists to provide the necessary labor, as I have seen postings about this here and elsewhere. One thing that would help it to attract said aid, would be to obtain 501-3(c) registry (i.e.nonprofit corporation status.) Has this been done yet?
Its always attractive to think in terms of a "quick hit" when contemplating a restoration of this type. Everone wants it now and prays for some "sugar daddy" to appear. But "sugar daddies" with those means are rare and their unalloyed involvement can sometimes prove to be a mixed blessing.
Several groups like Karasu's NCNG and the WW&F (and others) have shown that "slow and steady" can be quite successful. Restoration groups need the time it takes to organize effectively, cultivate community ties and support, and "grow" in-house expertise.
If you are building for the "ages" and truly intend the restoration to survive well beyond the present generation of supporters, "fast" is no substitute for a sustainable support organization.
My opinion.
