With the current economic crisis a Government could build the infrastructure as a way of generating some cash flow and reducing unemployment (instead of throwing it at the auto industry, one of which wasted it on developing a V8 that can run on 6 when cruising, but still a big engine even then, and they call that green
) , then make the railroad companies pay them back (interest free) at a pace that will not bankrupt them.
As to the cost of new loco's (1.75 to 2.25 million US$) if the change over takes 10 years about a quarter of the roster would be scrapped and replaced anyway (average lifespan in USA 40 years), so no extra cost there, the rest would be in for a rebuild in that time, so instead of replacing the prime mover and generator convert it to electric, the traction motors/bogie's/frame and body can all be reused.
I don't know but I think the bits needed would be cheaper than a new prime mover/generator.
Whether this would be political suicide for a Government or not I cannot say :hehe:
John, interesting read and something I never thought of.
Cheers David
