SAFEGE
SAFEGE (Seifejji?) is an acronym for the French consortium Société Anonyme Française d' Etude de Gestion et d' Entreprises (English: French Limited Company for the Study of Management and Business) and is pronounced SAY-fij in English.

Company
The consortium, consisting of 25 companies, including the tire-maker Michelin and the Renault automotive company, is a consulting and engineering buerau. It was formed in 1919 as Société Auxiliaire Française d'Électricité, Gaz et Eau, a holding company with interests in private water, gas, and electricity production and distribution. When in 1947, these public utilities were nationalised, the company became the engineering and consulting office which it is today, taking the name Société Anonyme Française d'Études, de Gestion et d'Entreprises.
Today the company is a subsidiary of Suez Environnement and specialises as a consultancy in water and environmental engineering,[1] but not only (bought IDC, etc.[2]) Its main market is France, with 60% of the turnover. It also is a leader in several consortias beneficiaires of lots from the EC FWCs (6, 11 and coleading the 2).[vague]
SAFEGE type monorail
SAFEGE gained international recognition for its design of a suspended monorail in the 1960s. The design team was headed by Lucien Chadenson.
Design concept
The design of the system entails suspending passenger cars beneath rubber-tired wheel carriages of the type used more conventionally in the Paris Metro. The carriages are enclosed and supported by a box-like track or beam, with an opening in the bottom. The rubber wheels of the train run inside the track, supported by flanges on the bottom of the beam.
Unlike previous suspended monorails like the Schwebebahn in Wuppertal, Germany, the tracks are not exposed to inclement weather, and do not need any cleaning or ice-removal systems. This advantage enables them to run in cities where ice and other conditions would impair the reliability of the system.
Test installation
The test track built in France by SAFEGE in 1959, was a 1.4 kilometre monorail line that featured prominently in the 1966 movie adaptation of Fahrenheit 451, directed by François Truffaut.[3]Although the track was dismantled not long thereafter, the original car survived longer.[4][5]
Market position
SAFEGE systems are the leading type of suspended railway currently in transit use, though this consists of just four installations of two different systems. Its chief and more numerous competitor in modern monorail applications are variations of the German-designed ALWEG system, in which the vehicles run on top of, and straddle, a solid beam.
SAFEGE type monorails in the world
- Mitsubishi Heavy Industries developed a working system of SAFEGE-type suspended railways, of which there are two in Japan. One is the Chiba Urban Monorail in Chiba and the other is the Shonan Monorail which runs from Ōfuna Station in Kamakura to Shōnan-Enoshima Station in Fujisawa.
- Two Siemens SIPEM lines exist in Germany, one on the Dortmund University campus, the other at the Düsseldorf airport. Siemens no longer actively markets this system, but does still deliver the software for the automatic operation of a SIPEM network and vehicles.
