A theme of this blog is that transportation technology is changing at amazing speeds yet the proposals for increasing freight capacity along the eastern corridor continue to assume the use of early 1950s technology (that was the time when locomotive power switched from steam to diesel-electric).
As an example of how technology is changing consider just three events from the past week — any of which could dramatically impact our project.
The Electric Truck
This week Elon Musk announced the Tesla electric truck. It will go from 0 to 60 mph in just 5 seconds (20 seconds while towing 80,000 lb). That’s faster than a Ford Taurus. It has a range of 500 miles at highway speeds (conventional trucks have a range up to 900 miles but many journeys are around 250 miles). It features, of course, highly sophisticated controls.
Given these figures one wonders if battery-powered trains will become feasible. If so the cost and disruption associated with overhead catenaries would be eliminated.
As discussed in an earlier post, the company Fisker has announced new battery technology that has an energy density 2.5 times greater than the batteries used in Musk’s cars and truck. (It needs to be stressed that there are still many technical obstacles to overcome.)
The city of Denver in Colorado has signed an agreement with the company Arrivo to install a maglev system in order to help solve that city’s serious traffic problems.
If all these changes happen in just one week, how will the industry look ten or fifteen years from now? It seems very unlikely that we will still be relying diesel-electric motive power or that the new transportation systems will still use steel wheels on steel rails.
