(approximate average from table 2 here.)
TOTAL ~ 38,000 kilometers of initially-proposed lines
Cost to roll out this infrastructure would be ~
18 million $/km
That seems quite low. Looking around further, estimates range as high as $220 million per mile. This likely includes intensive tunneling and difficult terrain. After translating that to km, my rough guess at a realistic average number would be $80 million/km.
The above number would be for laying out the infrastructure of tracks, trains, and trainports. Other costs would include paying staff to run it, and to pay for maintenance.
A big consideration is the benefit of amortization out over perhaps 50 years (this BETTER be able to last way longer, with regular maintenance). Can we afford $60 billion/year?
Other considerations are the savings from less reliance on cars, highways, airplanes, and gasoline fuel at unknown rising prices. Further are issues of externalities that this has a strong potential to circumvent.
To me, that makes a project like this look doable, with sufficient commitment.
agape to all,
