The Germans are working on a new kind of trackless trolley.



The article notes there's nothing new in an electrically-powered road vehicle, although those current collectors are a bit much.
So-called “trackless trolleys” – passenger buses operated electrically with double overhead lines to supply the power – are in operation in many cities including Seattle, San Francisco, the Ruhr region in northwestern Germany, Switzerland, and dozens of other locations around the world for many decades. But Siemens idea is to electrify one lane of a limited access highway for powering trucks. The trucks are equipped with a double pantograph current collector, somewhat similar to modern trains except there are two of them side-by-side. The trucks themselves are dual-mode, they can interchangeably drive from electric power or the usual diesel engine. The goal is to eliminate diesel exhaust emissions from trucks on major highways in urban areas. Los Angeles and several other cities are reportedly looking seriously at Siemens proposal.
Regular readers know there are trackless trolleys -- in Milwaukee locution, trolley buses -- in the Cold Spring Shops.


Destination: Freedom goes on with a suggestion.
The added costs of electric / diesel trucks is anyone’s guess, perhaps $20,000 per vehicle, maybe less, or possibly far more. It all begs the question, if you want to move freight through urban environments using electric power, maybe an invention that dates backs over 100 years and today is in widespread use on five or six continents is perhaps the way to go. What is this century-old invention that efficiently eliminates engine exhaust emissions caused by moving many tons of freight through heavily populated areas? The electrified railroad.
The proper locution is "raises the question," not "begs the question". Nitpicking aside, this is what an electrified intermodal train looks like.


Mantua, Pennsylvania, May 1958.

You'd have to raise that catenary a few feet to clear stack trains, although The Pennsylvania Railroad and Penn Central did handle autoracks on the Northeast Corridor.
