Besides this the use of single-phase cur-rent would make it impossible to use storage batteries to pre-vent possible interruption of traffic. Finally it appeared thatthe part of the line running in the country, comprising 22km ( miles), was too short to take full advantage of thebenefits of the single-phase transmission, while the use of ahigh-tension direct current, with the power house located atthe center of the system, would prove the most economicaland reliable. This road is not the first high-tension d. c. linebuilt by the manufacturers, as the Berlin Elevated Railwayhas been using 800-volt d. c. motors for some A TRAIN OF TWO MOTOR CARS AND TWO TRAILERS ON THE 990-VOLT DIRECT-CURRENT LINE BETWEEN COLOGNE AND BONN no difficulty in double tracking the line all the way whenevernecessary. The track is very substantially built, being cal-culated for wheel weights of 7000 kg (15,420 lbs.) It is pro-posed to operate the passenger trains up to a speed of 80 km(50 miles) per hour, running two trains each way hourly,carrying up to four cars, with a seating capacity of 250. A special difficulty arose in connection with the operationof this line, as the only power which was convenient was the550-volt direct-current used by the railway systems in Col-ogne and Bonn. A number of large electrical manufacturerswere asked to make bids for the power equipment. One planof the Allgemeine-Elektricitats-Gesellschaft contemplatedthe use of 6000-volt single-phase current for the line runningin the open country and 550-volt direct current in the plan by the same company i
