Tesco "Less CO2" Container Train in Newport Station, Edited Version, Newport, Wales(UK), 2015

I saw these containers a number of places in Britain, and they struck me as an often unexplored area of rail marketing, namely the lower CO2 emissions possible with rail transport. This has always been the main marketing point of rail transport, at least as a government policy, in the modern era, although obviously to work, such a policy has to be implemented reasonably efficiently. For example, a one-car freight train will not have the advantage of a 100-car freight train. Britain generally is somewhere in the middle, running 20 to 40 cars typically, as in the rest of Europe.
