Another reason libertarians should like rail it can be privatized

There's another reason why conservatives and libertarians should like rail. If government transportation systems get privatized in the future and many of them probably will thanks to the state of the economy it'll be a lot easier to find private buyers and operators for rail lines than highways. Private freight railroads in the US and some high speed rail lines in Japan make money. Private companies are anxious to partner with local governments building rail transit systems. The reason for this is simple, it's easy to charge people using rail for the privilege and hard to charge highway users. Yes there are toll roads but they're not common and generally only work where no other road is available. Few private entities are lining to up to operate highways, and I doubt it'll be possible to sell off most highways. Libertarians then should favor the transportation system that can be turned over to private enterprise not the transportation system created for socialists by socialists namely highways.
