An illustrated encyclopedic dictionary devoted to railway and steam technology
Tourneux, Félix
Encyclopédie des chemins de fer et des machines a vapeur
à l'usage des praticiens et des gens du monde
1844, Paris, Paul Renouard
First Edition
Overview
First edition of this richly documented encyclopedic dictionary of railway and steam technology, published two years after the Paris-Versailles disaster of 8 May 1842, which intensified public, scientific, and legislative scrutiny of rail safety. Tourneux places rail transport within its full nineteenth-century framework: mechanics, metallurgy, bridge engineering, steam power, law, tariffs, measurement, and administration. The alphabetical form gives that rapidly evolving vocabulary practical order, preserving a field still experimental and at times dangerous, yet increasingly shaped by the conviction that disciplined knowledge could make modern transport safer and more legible.
Inside the book
Arranged alphabetically, the work covers the technical, commercial, juridical, and scientific language of the railway and steam age. Entries move from mechanics to infrastructure and governance: "Abattre" (lowering heavy machine components for inspection), "Accéléré" (acceleration and motion), "Dent" (gear teeth), "Fer" and "Fil de fer" (industrial iron and wire), and "Ferme" (truss construction), alongside "Abonnement" (subscription contracts), "Barrières" (level crossings), "Bascule" (weighbridges), "Bassin" (hydrographic basins for route planning), "Jurisprudence," "Jury" (indemnification tribunals under the law of 3 May 1841), and metrological entries such as "Kilogramme" and "Kilomètre." Particularly notable is "Chemin de fer," which tabulates decreed, conceded, and operational European lines as of 1844, organized by country and illustrated with major routes across France, the British Isles, and the German-speaking states. "Accidens" treats railway danger with unusual frankness, describing uncontrolled steam as destructive and presenting accidents as a structural risk of technical progress pending fuller scientific control. The scope also includes steam navigation ("Bateaux à vapeur") and vehicle dynamics ("Lacet," on lateral carriage oscillation), with comparison to the 7-foot broad gauge (about 2.13 m) of the Great Western Railway. Illustration is substantial: twelve hors-texte engraved plates, including several folding sheets, plus numerous in-text woodcuts and technical diagrams. Together they depict locomotives, boilers, wheel and carriage assemblies, bridge and rail profiles, and related machinery, reinforcing the book's function as a practical technical reference.
Why La Fenice likes it
Shaped by the lessons of early railway mishaps, this dictionary turns steam-age complexity into clarity: law, commerce, safety, and iron networks spark into ordered, purposeful knowledge.
