According to the Association of American Railroads, freight trains are four times more fuel efficient than trucks, with 75% fewer carbon emissions for the same distance (it has a handy calculator here, if you want to plug in a few actual journeys). The video above shows off some new diesel locomotives that General Electric says are particularly efficient, using “11% less fuel than the existing locomotive average in North America.”
In rural Canada there are fewer and fewer trains. Sad to see tracks get pulled up in favour of more trucks on the highway. Mass transit seems more logical. What am I missing?
