Amtrak is promising high speed rail for the northeast corridor. Again. Only this time the plans are way more ambitious than the old Acela idea. Here’s a link to the complete proposal PDF.
For a mere $117 billion proposed spending over 25 years or so, Amtrak would build a new high-speed rail system linking Boston-New-York-Philadelphia-DC. Average speeds would be from 140 to 220 mph. The Boston to NY run would run 84 minutes.
Lest we forget, Acela promised speeds of 150 mph (which never quite materialized) and cost three times its estimate. But Amtrak swears it will make money, so everything will be OK.
