"Looking abroad, it's clear the US has far less invested in local and regional rail systems. With regard to high-speed rail systems, the US is conspicuously behind. France's TGV is moving people at 574km/h. China operates the world's first commercial maglev line while the famous Japanese Shinkasen goes without mentioning. In the US there is only one line in operation between DC and Boston with a few more planned as a result of the 2008 election in California.
The traditional barrier to implementation of rail systems is the initial investment costs, but in the context of economic stimulus, such investment sinks are actually desirable. The auto industry has clearly taken note with proposals from companies like Caterpillar for huge new infrastructure projects.
A friend who recently bought a house observed that real-estate prices are on the rise nearer to city centers, where the fallout of mortgage problems and expensive, time-consuming drives from the suburbs can be avoided. Recalling the huge number of urban revitalization plans and efforts to increase the viability of older city centers, it seems as though many municipal governments would also be in line to gain from the added density of rail systems and increased activity they can support in downtown areas.
Putting it all together, it seems like now would be a good time to direct the industrial capacity of the automotive and supporting industries to developing local and regional, high-speed rail systems to provide a more efficient and effective infrastructure basis for US cities while essentially creating a new market where competition from foreign car manufacturers will not be a problem. At the same time, a huge labor force would be required. The task would call for engineers for development, factory workers for manufacturing, operators, and maintenance workers. Caterpillar still gets to sell construction equipment. The inevitable stream of stores popping up around stations would provide new commercial areas. Last-mile bus and taxi services would also have a new place. The list goes on.
Besides the savings in fuel, the US could also gain international prestige and possibly help lead China and India away from our mistakes, helping to stem the rising demand for oil globally and avoiding the attendant international tension. Climate change is yet another win in this scenario.
It seems like we're not exactly headed in that direction, and I'm curious to see what Slashdot readers think of all this. What pieces need to be in place to make the investments pay off? What are additional resources that are required? Can the industries really make such a change of direction? Do we have everything we need in the US? How would such systems work out long term? Would the initial investments be able to pick up fast enough to stimulate the economy?"
