You're probably correct however it is apparently in "phase 1" of a government report, which will probably never happen like everything else that is apparently going to happen https://www.theguardian.com/environ...ld-slash-uk-road-freight-emissions-says-study
Yeah, running 25 kV high-tension lines all over places to which the public has free access! What could possibly go wrong?
Rail is great if you have large quantity of cargo moving from point A -> B (i.e. between big logistic center, or transports hubs like harbors) so you can build a significant portion of a train from this stuff. So the goes directly from A->B. The moment you have just a few containers going for A->B, then few A->C, then few A->D.. and then some permutations of these destinations, all efficiency of trains flies out of the window, because you need to do expensive yard switching with these vagons. Also the delivery times start to drastically increase. This is why heavy freight trains work so well in US. You have huge sparesly populated areas through which you just want to move stuff. You bring all the stuff you want to transfer to point A, at the edge of densly populated, then move it the 1000miles to point B, to an edge of another densly populated area... ideal train scenario. In Europe it is different. So when a container ships docks at i.e. Hamburg, you are able to build a full train to a logistic center in Vienna. But once in Vienna, you might have few containers going to Slovakia, few for Hungary, few for other parts of Austria... Then it is more efficient to put it on trucks that will deliver it directly to the destination, than trying to either schedule series of trains that will move it closer to containers destination, or waiting week or two, until you got enough freight for a train. _______________________ GAMETABLES4LESS, LLC
I suspect it will be more like the voltage that trams run on, something like 600v DC. Still potentially lethal but I've never heard of anyone getting killed off the overheard system on a UK tramway, as opposed to getting mangled by the wheels - which is just as big a risk as with a lorry in fact more so as most trams are either fitted with a lifeguard or some other protective system for pedestrians. We also managed nicely with trolley buses for many years, as do several countries around the world to this day.
