Locomotives are merely following the same formula that is presented above - i.e. that one giant train can carry far more containers per horsepower than a single-container truck can carry. The ideal system would be a sort of hub-and-spoke, where containers were moved to hub stations by locomotive, where they would be divided and sorted, and only the final local delivery would be handled by a truck at all. Now THAT would reduce some carbon emissions. Ummm…isn’t this exactly the reason why it would be preferable to use locomotives to move cargo containers rather than trucks?

Those big trucks being touted by the government are B-trains, a Canadian invention. Their second trailer is joined by a turntable rather than an A-frame making the units much more stable and better tracking than the truck-trailer type combinations prevalent in the UK and on the continent. The extra weight is spread over more axles so they create no more road wear per tonne than a normal truck. Once a truck gets over about 15 tonnes the weight doesn't make much difference in a collision with a car because of the huge mass disparity. All other things being equal you are much better off with fewer, bigger trucks because there are fewer opportunities for collisions. We use B-trains extensively in Australia and yes they are safer and more fuel and emissions efficient per tonne of payload carried. You have to restrict them to suitable routes, as we do, because they do take up more room on turns (swept path). Cheers, Bob Murphy Oz Hi.
