Not a Silver Bullet, rather many BBs. This article goes into depth regarding electrifying US railroads and the many benefits of doing so.

This is the kind of thinking we are in desperate need of around here. It is well thought out and possible. Here are some of the points made:

• technically feasible today
• reduced oil usage by utilizing the much greater efficiencies of rail based freight and transferring truck based freight to rail (and in some cases air freight)
• synergies with alternative energy sources along rail lines
• better use of current electrical infrastructure
• economic benefits
• decreased road damage
• safety
• national security
• job creation

This piece finishes with well thought out solutions.
