considering the current cost of gasoline, the level of reserves and the considerable technical problems to overcome if hyrdrodgen is to be a fuel, massively expanding the automobile infrastructure is probably unwise at this time.

Exapnding the rail infrastructure (i.e. rebuilding the rail infrastructure) to combat congestion and fuel expenditure is a good idea, if done correctly. I have serious doubts, however, that this is the correct way. Providing additional connections to well connected areas for freight isn't the answer (and what happens when you hit the borders of Texas?). Reinvesting in urban infrastructure is a much better solution.
