CAD of transit high speed electrified railway lines in Poland L. Mierzejewski & A. Szelag Institute of Electrical Machines, Warsaw University of Technology, PL Politechniki 1, 00-661 Warsaw, Poland Abstract The integration of Europe requires an efficient railway transport system which means electrified railways. As different traction systems are used in European countries (DC 1500 and 3000V, AC 15 kV 16 /3Hz, 25kV 50Hz) multisystem locomotives are constructed to be used on high speed trans- European lines. Due to the plans to build new high speed EUROCITY transit railway lines in Poland some study works have been undertaken to assess the readability of supplying multisystem high power high speed locomo tives by the functioning supply DC electric traction system on exis ting railway lines. These lines have been used for mixed freight and passenger (long-distance and local) traffic, but the heavy densed time-table of high speed trains creates new energy demands for which
