For a long period, they were perceived as flagships of the DB rolling stock. == Development == In the decades following World War II, the Deutsche Bundesbahn focused on purchasing a large number of standardised electric locomotives. The goal was to promote the electrification program and to replace older types of electric locomotives. A maximum speed of was deemed sufficient. With growing economic prosperity, competition with other means of transportation, especially automobiles, was increasing. During the 1950s, plans were made to enhance pre-war Class E 19 locomotives to have a top speed of , but the technical layout was out-dated and the braking system was deemed inefficient. The plans were revised to demand a top speed of , combined with a Co'Co' wheel arrangement to limit the axle load to 18 tons. Elements of the new class, such as high speed bogies, were tested with existing Class E 10 units. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「DB Class 103」の詳細全文を読む スポンサード リンク
