t of Con-tinental countries, 41.8 miles; and in the United States, 276.2 miles.It is said that the new plant of the Manhattan Elevated Railway Com-pany, of New York City, which will have a total power of 40,000 kilo-watts, equals in capacity the total electric power available for tractionpurposes in France. The United States has 76 per cent, of all the elec-tricity available in the world for traction, 76>4 per cent, of the electric-railway mileage, and 83^4 per cent, of all the trolley cars. A German steam road upon which electric traction has been triedis the Wannsee line between Berlin and Zehlendorf. Since August,1900, an electric train has been interspersed in the regular service, aspeed of about 25 miles per hour being maintained. The tram weighs193 tons empty and 220 tons loaded, and is composed of ten coaches,the first and last having three motors each of an aggregate capacity of975 horse power. It runs 225 miles oer day. the maximum speed being 882 THE ENGINEERING MAGAZINE.

31 miles per hour. Di-rect current is used at750 volts. The effici-ency of the powertransmission betweenswitchboard and axlewas found to be from70 per cent, to 85 percent. The governmentrailroad authorities have decided to discon-tinue the electric ser-vice, but the failure ofthe road has been duemore to half-heartedmeasures than to anydefect in the system. The first installationof a high-speed elec-tric road in Europe wasbetween Diisseldorfand Krefeld, a totaldistance of 13.6 miles,the longest stretch be-tween stopping placesbeing 10.4 miles. Sincethe road parallels thesteam railway for thegreater part of itslength, it is considerednecessary to maintain aspeed of 25 miles perhour on the openstretches. A speed of37.2 miles per hour hasbeen reached on trialtrips. The road doesnot pass through theintervening towns butonly touches the out-skirts. It is double- HIGH SPEED ELECTRIC INTERURBAN RAILWAYS. 883 tracked form Diisseldorf to Oberkassel, the terminus of the Diisseldorflocal traffic
