At Mult-nomah there were two 600-volt rotaries in parallel. Thesewere connected in series and a new 1200-volt rotary wasinstalled there. The trolley wire on the existing line wasre-insulated, and new substations were built south of Salemso that the spacing between substations is now between18 and 20 miles. All substations are of concrete and steel,and on the new line the company has also built a combina-. Oregon Electric Railway—] for unusual load conditions. Practically all of the electricequipment is of the General Electric make. When the line was acquired a transmission voltage of33,000 volts was being used. This was increased to 60, high-tension insulators were changed in accordance,and new step-up transformers were installed at the stationof the Portland Railway Light & Power Company, fromwhich all power used on the line is taken. All of thiswork in changing from 600 volts to 1200 volts was doneat night without any interruption to the service. PASSENGER STATIONS AND OTHER BUILDINGS At the large cities on the line, like Salem, Albany andEugene, the company has erected large modern passengerstations equal in appointments if not superior to thosewhich would be erected by steam railroads in cities of thesame size. In Albany and Eugene these buildings are de-
