t meeting A. I.E. E. and N. E. L. A., Portland, Oregon, March, 1914.—The Editors.) This development had its beginnings as far backas 1904, when a report was submitted covering theelectrification, by means of a 2200 volt system, of aportion of the line between Portland and Forest Grove,and Portland and Oswego, with a possible extensionof the latter line from Oswego to Oregon City. The report, however, was never acted upon, sothat when in 1909 a request was made for a new re-port, the advance in the field of electric traction since ment, manufacturers were requested to bid on 1500volt equipment as well as on 1200 volt. The savingin feeder copper possible with a 1500 volt system asagainst the 1200 volt, which, for the same loads andthe same percentage drop to any point is 56 per cent,caused the higher voltage to be adopted. Though noannouncement was made, for reasons of policy, at thetime this apparatus was purchased, it was the firstmanufactured for a trolley voltage of 1500, although

Interior Oswego Substation 1904, made it desirable to consider some other thanthe 2200 volt a.c. system. The Southern Pacific Company having decidedupon a 1200 volt system for its suburban lines aroundSan Francisco Bay, it was but natural that the sametype of system be given more consideration than anyother in electrifying the companys lines out of Port-land. At the time specifications were drawn up for thesubstation machinery and multiple unit car equip- due to unavoidable delays in construction it was notthe first road to be put into operation at that voltage. The first section of this system, recently com-pleted and put into operation, is shown on the accom-panying map. The 1909 report covered the electrification be-tween Portland and McMinnville of the then existingsteam lines. In 1911 a comprehensive report was madeby Robert E.
