Howard Elliott, The Truth About The Railroads (1913)
“ The use that the railways make of their cars is, therefore, of the utmost importance, not only to the railways but to the people. When a freight-car is standing still, it is doing no good to the railway or to the people, but the railways have had to pay for that car, and a part of their capital is invested in it. When it is standing still, it is not earning anything on that capital, and as the capital of the railways is a part of the national wealth, the usefulness of the national wealth is impaired by the loss incurred through the idleness of the car. ”
