Mr. James J. Hill, when president of the Great Northern, Northern Pacific and Chicago Burlington & Quincy railroad companies, applied the principle of quantity production to railroad transportation. Under his supervision locomotives and cars increased in size; this necessitated heavier rails and more substantial track; trains were not allowed to leave the terminals until a full load had been accumulated; regular schedules were of course done away with except for passenger and a few local freight trains. Other trains were to be run only at the full capacity of the locomotive. This was not conducive to speed, but the unit cost of hauling a ton of freight one mile was very materially reduced. The same crew with comparatively small increase in costs may operate a train of many cars about as easily as one of few cars. The same principle underlies the efforts of motor transport companies. They are increasing the size of trucks and loads to decrease cost. They have not used discretion, however, in this and their heavy trucks have ground to powder high-cost roadways with the result that public sentiment is reacting against them and regulatory laws are being passed by many legislatures. Increasing the size of the plant, train, or truck will not bring economies unless it can be run at its capacity load, consequently when the trade or traffic will not utilize full loading a smaller plant should be adopted. To run a 12 horse-power gasoline engine to turn a 1¹⁄₄ horse-power washing machine motor is no more foolish than to run 100-car locomotives to pull 2-car trains, or 7-ton trucks where the load never exceeds 2 tons, or 7-passenger automobiles with 1 or 2 passengers. The contention is well founded that western railroad methods are futile on New England railroads[160] and that if prosperity is ever to come to New England roads they must reduce their rates and rates can only be reduced by making the size and number of cars commensurate with the character and amount of traffic. In England where shipping distances are comparatively short the small van or car and quick deliveries have been evolved. In well-settled portions of this country, as in New England, similar practices might well be adopted that the railways may not be entirely eliminated and the public forced eventually to resort to more expensive transportation methods when both direct and indirect costs are considered over the public highways.
