M. Mordey and B. M. Jenkins, M. Inst. C. E. Theauthors refer to the recent Inner Circle arbitration in London as tothe advantages of different systems of electric railway operationand then take up a general review of the various electrical systemsapplied to or proposed for railway service. A digest of the paper. Plan way—was next described, in which high-tension three-phase alter-nate-current transmission was used with step-down transformersand rotary converters, to give direct current to the railway. Theexisting alternate-current methods were all described under three-phase working, and it was shown that on the Continent there wasa decided tendency to work out the more difficult traction problemsby the use of the three-phase alternate currents, not only for trans-mission, but also for working the trains themselves. A table wasgiven containing particulars of the principal three-phase electricrailways. The authors then proceed to discuss the comparative advantages•and disadvantages of these three classes or methods, giving curvesto illustrate the efficiencies of the sub-stations according to themethods adopted, and a table showing corresponding costs of theplant, etc., required. The advantages of the direct current and com-bined methods in their easy use of a
