Also, when as is the case on Local lines the weight of the locomotive is less than the above, the two costs calculated on the basis of a locomotive weight of 60 and 54 tonnes respectively, per tonne-km. and per passenger-km., are almost exactly the same. For the meaning of tins term, see " The Commercial Trace," forming Part I of this Work, p. 69. Tk The weight of the locomotive need not have appeared at all in the formula for the D working-expenses if the constant quantity." had been put = b. The expenses per trainkin, increase, on the contrary almost in equal ratio with the weight of the locomotive. But since the working-expenses in Trace-problems should be calculated not from the number of traia-kms. but perferably from the number of tonne-km. and passenger-km., it is permissible in every case to assume as a basis the weight of a goods-locomotive to be 60 tonnes, and that of a passenger-locomotive as 54 tonnes. If the number of train-kms. has to be dealt with in calculations, then for different 72 60 72 weights of locomotives, for example for 72 tonnes, such a train is to bo treated as '" = 1'2 72 goods-trains, or as j = T33 passenger-trains, as the case may be. §14. Determination of the Working-Expenses when the Traffic is not the same in both directions. When the traffic preponderates in one direction--which for this reason will hereafter be called the Main direction--then the train-load in this direction must of necessity be greater than in the opposite direction, because--owing to the return-journeys of the locomotives and vehicles--the number of trains in both directions is necessarily the same. If the paying-load carried in the main direction be Tt the weight of a train ca...

LAUNHARDT, Carl Friedrich Wilhelm was born in 1832 in Hannover, Germany.
A civil engineer who applied mathematical techniques to economic problems. His writing on railway pricing virtually discovered the theory of marginal cost pricing as well as its implication of deficits for decreasing-cost industries, and continues to influence current thinking on railway tariffs. He also made significant contributions to industrial location theory, particularly market area analysis.
A version of the pole principle for finding plant locational equilibrium points is to be found in the seminal 1882 article.
His Mathe
matische Begründung is, among other things, the first ever text of mathematical economics. In addition to original results on location, it taught the doctrines of Jevons and Walras.
Professor Engineering Science, Rector, Polytechnic College, Hannover, Germany, 1869-1918.
Honours Honorary Doctor Dresden Institute, Institution Technology, 1903.
