( see my post above this regaruding local laws and trains )

High speed trains generally have very wide sweeping turns to allow the train to take the corners at top speed.
That said, I never really understood why the US never bothered investing in high-speed rail like Europe and Asia did.

It will still take several hours to travel from houston to dfw by train. 4. it will not be a direct route.
Also, the Souce is very very biased, Its all coming from the guy who is seeking investors, If I was asking people to give me money, I would tell them all the good things while hiding the bad stuff as well.

So you are making the case that this is a bad investment.

1) Neither does any other form of transportation.

2) This is obvious. Turnpikes are the same way.

3) We have no clue what the average velocity of the train is until more variables are determined. It currently takes 4 hours to travel 240.6 mi on I-45 N obeying speed limits. Are you 100% certain that a high speed train would be just as slow? We have no idea if there is an express line, a line with stops, how long those stops are, where those stops are, etc. It is impossible to speak with any real certainty about the rail line.

4) This is conjecture.

Our population density in the vast majority of the country does not warrant the investment. Canada is very similar in this regard. It makes more sense on the east coast (and this is reflected in the much higher density of rail lines.) Americans also like driving in general, and it is often preferable to public transit options over long distances.

Population density--to hit high enough numbers of riders, you'd have to go through a lot of cities/towns--more stops would increase the transit times and generally work against the point of a high speed rail.

But with 1), there's a difference in stating the maximum speed capacity of something vs. what it will travel at. In my example a bit ago, the high speed rail in NM said it could hit 150+ mph (IIRC) in pre-construction studies, but in practice, the average speed between stops was only something like 55-70mph. That's the devil in the details--max speed is irrelevant in comparison to actual average transit times between stops/cities.

I completely understand your point, and I agree. You are differentiating between maximum velocity and average velocity. I was merely stating that because a mode of transportation does not achieve its full maximum velocity at all points in time is not a really a reason for detraction. Your point deals more what what I said in "3)." Poor planning can hamstring any speed gains made, and generally produce gross inefficiency for the passengers. At the end of the day, that is what it is all about: efficacy. After all, it is the only reason we put up with the airline and TSA. Perhaps with this being a private investment, the impetus to deliver on this model would be greater.

A direct houston to dfw rail at 10billion, Yes, I would call that a bad investment.

a rail that traveld through all my previously mentioned cities, no, if the route was proposed through Austin, I would happily vote for it if it came up to that.

and I still stand by my number 3, there will be stops that take time to unload passangers and cargo. and an express line or whatever you will wish to call it, still will require several miles of additional rail, as well as a few more trains, and all that will add to the cost of a ticket. and will still take a few hours to travel. Simply once again, to the rules and regulations trains must follow ( that you seem to keep ignoring ) and lets not forget, the flight from DFW to Houston is only 2 hours ignoring the time it takes to get into the airport to be boarded. I imagine in todays terrorist feared society that train commuters are subject to similar x-ray screenings and baggage checks as well.

The few places I have rode in trains or subways, they worked very well because they were all located along tightly nit cities. Not to mention, how spread out houston and dallas are, it will still require a car ride to get to where your going, or if you are lucky, hop on DFW metro rail to get you along.


and as far as public vs private funding, yes, it does have a better chance of being built, but that just means the profit for such a project would come mainly down to the commuter ( assuming this a strictly passanger rail line )

Why does the train need to travel at ground level? Why not elevate or sink the track to avoid all road crossings. And if this is an express line, those only have 2 stops.

Think of all those that commute between the two cities. Now they can avoid all the misery of the airport and its security and just hop on a train.

^ this. I question how many people will be able to take advantage of the train because of how spread out Dallas and Houston is. If you take the train to save time, you lose the time you gained by using the public transportation system. If you take a taxi, the price of driving your own vehicle would have probably been cheaper than the train ticket + taxi. To me, the people that benefit would be those that have someone they know that can pick them up at the train station. There is the possibility that you don’t care about the price of traveling because you hate driving. Then this is a luxury.

Expensive.

Overpasses and underpasses each require environmental impact studies, more land, and additional months to construct.
