There are a number of issues involved:
- You cannot realistically share rail between freight that moves 75 mph at its fastest and 200+ mph passenger traffic. Causes way too many scheduling difficulties.
- Obtaining right-of-way and building overpasses to avoid grade level crossings where automotive traffic crosses the rails. I'd hate to see a 200+ mph train hit a semi. Currently train vs. auto doesn't wipe out the train. All bets would be off at that speed, I think. Plus, as the initial clause suggests, paying for the land for these lines will be horribly expensive. Then there is the 15 - 20 years of the endless environmental impact reports.
- Mountains. I don't know about the Chinese lines, but no other lines cross mountains like the Appalachians, let alone the Rockies or the Coastal ranges like those of Mt. Ranier, Mt. Hood, or Mt. Shasta. Generally, mountains mean drilling. That is what Japan and Switzerland have had to do, and their mountains are no where near as tough as those of North America.
- This is a capital improvement project that would easily run into the tens of trillions of dollars. Do we have the national will to do this? What if we tried to do the National Interstate project today rather than in the 1950s?
- The inveterate whiners and complainers would swarm the legal system. All the millions of NIMBYs would each demand (and likely receive) their day in court. How many spotted darters or desert tortoises (just to name a few) would be endangered by this? Can we build new rail lines back east? Is there room in the Northeast? The mid-West and West would be easier, but I can just hear the screaming now.
I know we are going to end up doing this, but I don't see it running any earlier than 2035. (Admission: I work in the rail industry for a rail supply corporation).
I know billions have been promised, but this job could cost between $10 and $20 Trillion dollars. The amount of wayside equipment alone is staggering. As a comparison, those costs were approximately $15000 per mile in 2005 (Source:

Since this would have to be a minimum of 2 lines, and likely 3, estimated cost is a couple MILLION dollars per mile, just to construct the line. While this won't be the full 99,000 track miles currently in existence, I think the total would be a minimum of 15,000 (parallel the interstates: One parallel to the US - Canadian like I-90/80, one mid-way like I-70/64, and one southern like I-40/10 (each about 2500 or so miles). Then one paralleling I-5, one like I-15/25/35, one like I-55/65/75, one between I-75 and I-95, and then a final one like I-95 itself with each of these essentially 1000 miles, plus lateral linkages. So we have a minimum (in 2005 dollars) of $15,000,000,000 for a single line track. Double or triple the per mile cost in foothills and minimum of $1B per mile of tunnel(as an example, the Chunnel cost $15B for 95 miles of track, and that was easier to build and of shorter duration to build). Wayside equipment costs would be around $220B overall. Then figure cost overruns, stupidity of people, and graft then spread the increasing costs over 20 years, and it is at least a couple of trillion dollars.
I do not doubt at all that we have the expertise to build this. The question is do we have the national will? Congress now fights horribly for social programs vs defense programs. Could this fight even take place?
And more importantly: Should it?
