"Archeology
is honored in every domain, except for building processes and arts; We
know more details about the Egyptian and Babylonian civilisations that
about the origins of our industries. Universities chairs exists for each
History segment except for History of technical applications of sciences."

!! ... !! Stay tuned.
Intentions
I sincerely hope you'll enjoy and have a great time visiting
this site. Frequent Very
irregular updates.
A brief (hum!) introduction to the advantages and benefits of (efficient) compound systems applied to locomotives based on Stephenson's concepts (well documented arguments and examples extracted from Andre Chapelon's books, conferences, experiments, reports and letters), as well as other reasons that research for greater efficiency was so strongly supported here in France. There are historic, scientific, economic, political, geographic, and even philosophical reasons.
& How
Condensed technical history of French and foreign pre-Chapelon compound locomotive designers whose work led to the "du Bousquet-de Glehn" French standard arrangement for compound locomotives.
Designers
Gaston du Bousquet
Anatole Mallet

Index of technical drawings and graphs, indicator diagrams, ...
Miscellaneous
Short history and description of railroad companies in France
Typically French accessories visible on pics, for those who are curious
A few words about French numbering systems
Glossary of french acronyms used
Live steam models of french locomotives
F.A.Q.
Learn the right way to operate well-designed single or dual expansion engines for maximum efficiency, minimum water consumption and minimum engine, mechanism and chassis wear, as defined and taught by Chapelon. Superiority of his methods has been largely proven by 40 years of use in France with thousands of engines, and it has been fully demonstrated by mathematical models as well. Very unexpected for experienced, non-french steam locomotive drivers. They may learn they have always driven poorly designed machines! Or used good ones inefficiently.

Ce site a pour vocation de mettre à disposition de toute personne ou institution interessée par la question de la documentation: Iconographie, informations historiques, documentation technique, ... sur les locomotives à vapeur françaises en général et sur les locomotives compound en particulier, ...
......... Avant, c'était plus long mais pas forcément meilleur pour autant .............
... et ne publierai donc ce site QU'EN ANGLAIS, dans l'optique d'une diffusion de ces information hors de nos frontières, ce qu'aucun Français (sous entendu quelqu'un pouvant avoir un accès direct à l'information) n'avait songé à faire me semble t'il, même pas sur un média traditionnel...
.En fin de compte devant l'afflux de demandes
sympathiques et pressantes (!! Je prends mes rêves pour
des réalités!!) et exclusivement parceque seuls les imbéciles
ne changent pas d'avis, la page d'accueil des
Locomotives
Compound "type Français"
Est maintenant - partiellement - disponible!!
Qu'on se le dise!!
