The initial two were built by the Southern Railway at Ashford Works in 1941 and 1945 and were numbered CC1 and CC2 - the Southern Railway latterly preferring French practice for locomotive numbers which also gave an indication of the wheel arrangement. Electrical equipment was designed by Alfred Raworth and the body & bogies by Oliver Bulleid. CC2 was modified slightly from the original design by C. M. Cock who had succeeded Raworth as Electrical Engineer. The third was built by British Railways in 1948 and numbered 20003. == Southern Railway nos. CC1 and CC2 == Externally, it was clear that the cab design owed a lot to Southern's experience with the 2HAL multiple unit design. It has even been suggested that (in true Southern tradition) this was because the jigs for the welded cabs already existed and thus made for speedy and cheap construction! At the outbreak of war in 1939, most construction projects were put on hold in favour of the war effort. Construction of CC1 and CC2 was exempted from this, because of promised savings in labour and fuel over steam locomotives. Construction was not smooth, however, and was brought to a halt several times, due to shortage of resources. After nationalisation in 1948, British Railways renumbered them 20001 and 20002 respectively. 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「British Rail Class 70 (electric)」の詳細全文を読む スポンサード リンク
