I can say with certainty that no one on this planet is more in love with railroads, and passenger trains, than me. But the reality, in my opinion, makes the idea of modern day passenger service on almost any but intracity light rail service, in the US impracticable.
Even in the days when rail was the only feasible form of long distance transport, passenger service never paid its own way. While trains like the Daylight or the Twentieth Century Limited generated a lot of revenue, that revenue was purchased at the expense of profits from government mail contracts and highly regulated and expensive freight tariffs. No one was paying attention to this while the railroads were awash with dollars. With the DC3, mail contracts started to disappear, as people did not wish to wait for a week for transcontinental mail to be delivered, although we often still do for even intracity mail:hehe: .
With the interstate highway system, there was at last a freight competitor to rail. That meant that the railroads had to become lean and efficient. That also meant what was left of this source of money could no longer be pumped into passenger service. By 1980, and almost overnight, single car loadings became a thing of the past. That kind of traffic moved to trucks or to intermodal service.
To the proponents of "high speed rail" and other such concepts, I issue a challenge, and if it is met, I will forever hold my peace and be embarassed.

The challenge is as follows:
1. List ten independent high speed passenger lines in the US or anywhere in the world that can operate without massive direct or indirect government subsidies.
2. If you can't do that, say where the subsidy comes from. If you say "the government," tell us where the government gets it, and be sure to tell us where the "big corporations" get the money to kick in. I'll help you on this, it's the people who don't use the rail line.
3. Propose a high speed train line that can pay for construction and operation from traditional financing and the fare box and I'll suport it and buy stock in it. Then you can build it and make a fortune.
It seems to me that propping up outmoded operations, companies, and methods just diminishes wealth and slows innovation.
Ok, all you fellow railfans, tear me apart.

I think I have to get a load of Hydrogen Peroxide, gauze, and adhesive tape.
