Jules Petiet (5 August 1813 – 29 January 1871) was a French mechanical engineer who worked on the early development of the French railway network. He was the Chief Engineer of the ''Chemins de Fer du Nord'' from 1845, and became a locomotive engineer from 1848. From 1868 until his death, he was head of the prestigious engineering school ''École Centrale Paris'', of which he was also a graduate. Petiet's name is one of the 72 names inscribed on the Eiffel tower. A street in Paris, rue Petiet (at Épinettes, 17th district) is named in his honour. ==Locomotives== Petiet expanded the fleet of Nord locomotives from 187 at his appointment in 1848 to 841 at his death in 1871. He designed a class of 0-8-0T locomotives known as ''Fortes Rampes''; and built 20 even bigger 0-6-6-0 tank engines. Looking like a pair of 0-6-0s back-to-back, they had a long-rigid chassis. They were not as powerful as anticipated, and Petiet's successor rebuilt them in to forty 0-6-0T locomotives. He introduced the Crampton locomotive to the Nord (and France), and developed an A3A (0-2-6-2-0) Crampton-style tank locomotive. Nicknamed “Camels”, eight were built, but they soon were sold to the Nord's Belgian subsidiary ''Nord-Belge'' 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「Jules Petiet」の詳細全文を読む スポンサード リンク
