Jules Petiet
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 into forty 0-6-0T locomotives. He introd ...

École Centrale Paris
École Centrale Paris (ECP; also known as École Centrale or Centrale) was a French grande école in engineering and science. It was also known by its official name ''École Centrale des Arts et Manufactures''. In 2015, École Centrale Paris merged with Supélec to form CentraleSupélec, a constituent college of the University of Paris-Saclay. Founded in 1829, it was among the most prestigious and selective grandes écoles. Rooted in rich entrepreneurial tradition since the industrial revolution era, it served as the cradle for top-level engineers and executives who continue to constitute a major part of the industry leadership in France. Since the 19th century, its model of education for training generalist engineers inspired the establishment of several engineering institutes around the world, such as the École Polytechnique Fédérale de Lausanne in Switzerland, Faculté polytechnique de Mons in Belgium, as well as other member schools of the Ecole Centrales Group alliance ...

Chief Mechanical Engineer
Chief mechanical engineer and locomotive superintendent are titles applied by British, Australian, and New Zealand railway companies to the person ultimately responsible to the board of the company for the building and maintaining of the locomotives and rolling stock. In Britain, the post of ''locomotive superintendent'' was introduced in the late 1830s, and ''chief mechanical engineer'' in 1886. Emerging professional roles In the early Victorian era, projected canal or railway schemes were prepared by groups of promoters who hired specialists such as civil engineers, surveyors, architects or contractors to survey a route; and this resulted in the issue of a prospectus setting out their proposals. Provided that adequate capital could be raised from potential investors, agreements obtained from the landowners along the proposed route and, in Britain, an Act of Parliament obtained (different terminology is used in other countries), then construction might begin either by a new compa ...

Crampton Locomotive
A Crampton locomotive is a type of steam locomotive designed by Thomas Russell Crampton and built by various firms from 1846. The main British builders were Tulk and Ley and Robert Stephenson and Company. Notable features were a low boiler and large driving wheels. The crux of the Crampton patent was that the single driving axle was placed behind the firebox, so that the driving wheels could be very large. This helped to give this design a low centre of gravity, so that it did not require a very broad-gauge track to travel safely at high speeds. Its wheel arrangement was usually or . Design variations Because the single driving axle was behind the firebox, Crampton locomotives usually had outside cylinders. However, some inside cylinder versions were built using indirect drive, then known as a ''jackshaft''. The inside cylinders drove a crankshaft located in front of the firebox and the crankshaft was connected to the driving wheels by outside rods. Some long-wheelbase s we ...
