Where is the US economy headed?

I think it is eminent, and not at all iminent. Moreover there are limits on the power of government to seize property this way for the benefit of private developers.

Imminent

Using that process to take private property in order to hand it over to the railroads (corporations) is technically possible but dicey, it tends to get very expensive as everyone heads to the courts to litigate. In Tacoma Washington we have had a couple blocks of downtown which is needed to extend commuter rail (Sounder) to Lakewood held up in litigation for years, as not only the property owners have standing to challenge the plan in court but seemingly so does just about every other individual, group, or government agency. Needless to say but the project is now many millions of dollars over the intended budget, to pay for study, litigation, and as inflation has caused the delay to raise other costs.

That problem will be mitigated by using existing railroad tracks, and the building of above ground bridges where need be.

That's cool as long as they don't use any federal funds.

They will be using the money that Wisconsin and some other states didn't want to use for rail projects.

That's unacceptable.

And the cost of buying a right-of-way thru farmlands will be quite high.
Either that, or the state spend millions litigating for the land.

If they use existing railways, how does that add right of way cost thru farmlands?

You mentioned building above ground bridges.
The footprint to build a bridge, and allow an access road for maintenance reasons is quite large.
The farmers wont want to give up any land without getting paid for it.
So, if the state tries to use eminent domain, they can probably expect a court fight.
If they try to pay for the right of way, the farmers will demand a pretty penny for it.

Above ground bridges are planned mostly in metropolitan areas. There's already a rail line between SF and Los Angeles, and Sacramento to SF. What farm land are you talking about?

High speed rail will require completely new and segregated road beds with grade separated intersections everywhere - i.e. lots of new land and very high cost.

High speed rail = Major Boondoggle

Correct. But why does it work elsewhere?

Very large government subsidies and relatively shorter distances between major terminals make it work in Europe.

If I translate it correctly, you think that such is a "a project that wastes time and money".

So I may ask you why elsewhere exactly this is the main source for railway companies to earn money?

Our major railway company, Deutsche Bahn, had to finance it themselves. Similar in the UK.

Surely, it may be true for China.

But everywhere land is needed etc ...

The distance from Copenhagen to Madrid is over 1,200 miles. The distance between San Francisco to Los Angeles is 347 miles.

There will be some short distance stops between San Francisco and Los Angeles. I'm not sure what you're trying to say.

GEORGE SOROS AND HIS DEMOCRAT PARTY EMPLOYEES ARE ATTACKING AMERICA’S CONSTITUTIONAL GOVERNMENT AND AMERICA’S CAPITALIST ECONOMY

George Soros and his Democrat Party appear to believe their ends justify their means.

George Soros in his 1995 book, page 145, Soros on Soros, I do not accept the rules imposed by others. If I did, I would not be alive today. I am a law-abiding citizen, but I recognize that there are regimes that need to be opposed rather than accepted. And in periods of regime change, the normal rules don't apply. One needs to adjust one's behavior to the changing circumstances.

George Soros has owned and directed the Democrat Party since December 2004.

"Sam Hananel in his associated Press article, December 10, 2004,"] On December 9, 2004, Eli Pariser, who headed Soros's group Moveon PAC, boasted to his members, "Now the Democratic Party is our party. We bought it, we own it."

Soros … pushed for the Bipartisan Campaign Reform Act of 2002 which was intended to ban "soft money" contributions to federal election campaigns. Soros has responded that his donations to unaffiliated organizations do not raise the same corruption issues as donations directly to the candidates or political parties.

Soros gave $3 million to the Center for American Progress, committed $5 million to MoveOn, while he and his friend Peter Lewis each gave America Coming Together $10 million. (All were groups that worked to support Democrats in the 2004 election.)

George Soros has directed the members of the Democrat party to pass or continue legislation that violates the Constitution of the USA as lawfully amended. George Soros directed the federal government to adopt and/or continue the following such programs.

• Healthcare Reform:

National health reform is here. The Patient Protection and Affordable Care Act and the reconciliation bill are law. Together, they will trigger sweeping changes and disruptions — some rather quickly and some over many years.

What's really in Obama's health care reform bill? Almost no one knows, and here's why: It's 1,017 pages long and written in an alien form of bureaucratic English that can barely be decoded by earthlings.

The Constitution does not delegate power to the federal government to transfer wealth from those who earned it to those who did not and do not earn it. The Constitution does specify that the federal government can take a person’s property to provide for the common defense and the general welfare of the United States.

The powers not delegated to the United States by the Constitution, nor prohibited by it to the states, are reserved to the states respectively, or to the people.

George Soros’s Democrat Party adoption and and/or continuation of the previously listed programs (Healthcare Reform, TARP, Stimulus, Fannie Mae, Freddie Mac) , are evidence that they are adhering to the enemies of the USA, giving them aid and comfort, and arethereby guilty of committing treason.

Article III (1791). Section 3.
Treason against the United States, shall consist only in levying war against them, or in adhering to their enemies, giving them aid and comfort. No person shall be convicted of treason unless on the testimony of two witnesses to the same overt act, or on confession in open court.
The Congress shall have power to declare the punishment of treason, but no attainder of treason shall work corruption of blood, or forfeiture except during the life of the person attainted.

The Constitution of the USA as amended is part of the supreme law of the land.

Article VI
All debts contracted and engagements entered into, before the adoption of this Constitution, shall be as valid against the United States under this Constitution, as under the Confederation.
This Constitution, and the laws of the United States which shall be made in pursuance thereof; and all treaties made, or which shall be made, under the authority of the United States, shall be the supreme law of the land; and the judges in every state shall be bound thereby, anything in the Constitution or laws of any State to the contrary notwithstanding.
The Senators and Representatives before mentioned, and the members of the several state legislatures, and all executive and judicial officers, both of the United States and of the several states, shall be bound by oath or affirmation, to support this Constitution; but no religious test shall ever be required as a qualification to any office or public trust under the United States.

George Soros has declared his intention to create a new world order through the suppression of the U.S. economy.

If I'm not mistaken when the British Government privatized its railroads they separated the entity that qwned the tracks and the entities owning and operating the trains. In any event they were government owned and operated for about 30 years after WWII.

Here, it is very difficult to run passenger rail transport profitably, based on the fares alone. Even urban rail systems require large subsidies to operate. This may reflect the greater preference of Americans for automobiles and/or our relatively lower taxes on petroleum. Finally our cities are generally less densely populated anf more spread out than European cities, making passenger rail transport a bit less attractive. Our cargo rail system is extensive and very efficient.
