Too much
A cost of $383 for every man, woman, and child in America.
The operating surplus likely doesn't include the repayment of the
capital to build it.
Rail is very noisy.
A much better alternative would be to install a permanent magnet
maglev Levx system www.levx.com, which costs between $1-2
million per mile for the track, is very fast and extremely quiet, has
much lower maintenance costs than rail, requires much less
energy to run than rail, can incline up to 45% and make sharper
turns so it can avoid infrastructure damage, and is US invented
and made.
