Polish State Railways Electrification

Polish State Railways Electrification.

British contractors have recently taken a prominent part in an important continental electrification scheme. This is the conversion to electric traction of the Warsaw suburban lines of the Polish State Railways, undertaken mainly by the English Electric Company, and the Metropolitan-Vickers Electrical Export Company. The complete scheme covers the electrification of the Warsaw railway junction and suburban tracks radiating from the centre of the city to Otwock, Zyrardow, and Minsk. It involves about 150 miles of main-line and 30 miles of sidings. Overhead transmission is employed, with current at 3,000 volts, D.C. For hauling fast passenger services and freight trains, six 2,200 h.p. electric locomotives are employed. These each weigh 78 tons, and are of the B + B type, having four driving axles, each equipped with a 550 h.p., 1,500 volt motor arranged two in series. The control is of the electro-pneumatic unit-switch type. Ordinary passenger services are maintained by multiple-unit trains, each consisting of one motor car

and two trailers. The motor car has four coach-ventilated motors of 200 h.p., 1,500 volts, two being connected in permanent series. A second driving position is provided on the rear trailer car, this being articulated with the non-driving trailer by a common bogie. The railways of Poland, although not so well-known as some systems, form a most important means of communication in eastern Europe.
