Actually I could see high speed rail as a big ticket project that is doable in my lifetime with the right mindset. But I wouldn't completely market it as a transport project.
It's really an incredibly large economic stimulus and a jobs program. Think of all the jobs you will create at the steal mills, and the mines that provide them with raw materials to make the rails, and the jobs at the quarry for the ballast. And that's not even getting into the fun stuff yet like bridges, tunnels, and stations. Now you're adding even more industries into this picture. But don't forget to provide all of these industries with raw materials you have to pay people first to obtain the raw material, and then ship the raw material. And that's all fine and dandy but then you have to pay someone to move the raw material to the construction site.
Then you have all of the engineers, foreman, journeymen, and other crafts that are all involved in the construction and eventual maintenance of the system which are all good high paying jobs. Thats before stopping to think about managers, and other departments inside the company.
So really if you spend a trillion dollars or a few trillion dollars on a comprehensive High Speed Rail System you are creating a major economic stimulus for the entire nation. You are having hundreds of thousands employed either directly or indirectly. And each one of those dollars is filtering thru the economy multiple times. Its the basic principle that if you give me a hundred dollars. I'm then going to spend it on the class I'm getting tutored in which will eat half of it up. But then my tutor is taking that money and buying things for her life. Then the rest of that money is being spent on things like food, and other items I need which is keeping those businesses in business. Economic stimulus when done right is a cycled in the economy multiple times. The problem is in this country we tend to give a lot of money to the top earners who already have enough income what is a bit more and they sit on the money and don't invest it.
So if we were to directly invest in a HSR system we would directly and indirectly have a very large economic stimulus. And that's not even factoring in how ridership will work and how businesses will grow around the system. If you would have asked in the 1950s about the Interstate Highways I'm sure there were several people who said this was too big of a project that we couldn't afford it. But we did and it turned out to be a massive economic stimulus up until just recently. Now it's basically reached the end of the road to where it's creating new economic activity.
Here is a quote by Dr. Neil de Grasse Tyson on the Interstate.
"We didn't build the interstate system to connect New York to Los Angeles because the West Coast was a priority. No, we webbed the highways so people can go to multiple places and invent ways of doing things not thought of by those building the roads"
High speed rail is essentially the same exact principle New York to Los Angeles is not the real priority and it shouldn't be. We would travel on it naturally were railfans but we are a vast minority in the population. But there is a large intermediate base that might take that New York to Los Angeles line for short distances like New York-Buffalo, Cleveland to Kansas City, Kansas City to Flagstaff. It's not just about the idea that the rail connects both coasts, its that it provides opportunities for everyone on the system to benefit equally.
In my mind the best high speed rail system is centered around specific hubs in the country with hub to hub trains along with a bunch of spokes coming out of them that are conventional trains and high speed trains. You can have a hub in New York, Atlanta, Chicago, New Orleans, Dallas, Denver, St. Paul, Seattle, Los Angeles, and such other places. While the trains wouldn't have a super large affect on rural America there is no reason you couldn't throw stations on rural areas and run some form of a milk run using conventional equipment that's timetabled into the greater system to allow connections.
We need to think big in this country that is the only way we can accomplish things. When Kennedy said we would get to the moon by the end of the decade no one thought it was doable but yet we did it. This country is capable of doing great things you just have to get the ball rolling.
Also if you want indefinite funding for the high speed rail network brand the bill "The National Defensive Railway Act" and talk it up on how high speed trains will allow for rapid troop deployment anywhere in the nation, and how they can handle more troops and equipment than the existing air infrastructure. If you do it right you might just get a blank check. The truth is the interstate and the railways are part of the national defensive infrastructure of this country. It is how we can move troops, military equipment, and the raw materials to produce equipment and food to feed the troops. It is worthy of investing just because of that alone.
