Synthetic oil has been around for a long time,
Agip comes to mind, they made “oil” for the German army…they are still in business, Italy…
Cost of structure is still the same problem it was 50 years ago, which is why cantanry will not appear.
Its easier and cheaper to generate the juice “on site” with some engine turning a alternator.
What will power the engine, who knows, but bet on technology finding something efficent for the time, after all, the driving force of all of this is profit, and profit drives technology.
Lots more containers, lots more bulk cars, less boxes, big, real big tankcars.
Locomotive will look pretty much the same, areodynamics are just for looks, on something that weighs 200 tons, its a moot point.
C-C trucks, and the ability to steer them, is here to stay.
B-B switchers too.
Like Dan said, there will be a shift in the way business is done.
The Class 1s will carry it across the country, and deliver the goods to roads like mine, one netural railroad to serve most of a city or county/location.
The bucks are in the bulk stuff, containers everywhere, unit trains too.
LCL carloading will be history, look to FedEx and UPS for that.
Passenger service, maybe.
Local commuter rail, well, there really is no choice on that.
Cities have grown to the point they have no choice, there isnt enough real estate to build freeways big enough to remain fluid, and if they could, you would have to carry canned air around with you, the real stuff would be unbreathable.
Mass transit rail is coming back, big time.
