SAFEGE 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.

Monorail safege


Company

The consortium, consisting of 25 companies, including the tire-maker Michelin and the Renault automotive company, is a consulting and engineering bureau. 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, but not only (bought IDC, etc.) 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).

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.Although the track was dismantled not long thereafter, the original car survived longer.

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. In addition, from early 1964 to December 1974, a 0.5km single-line ran between Higashiyama Zoo and the nearby Botanical Gardens in Nagoya, Japan. While initially popular, it also suffered from mechanical problems and after the first two years of operation, the novelty wore off and it began making a loss. Plans to expand the zoo and gardens hastened its demise, although the car and a section of track is preserved at one of the stations. While it was initially marketed as a ride, rather than a means of transport, a fare was charged, making it the first revenue-earning SAFAGE/Mitsubishi-type monorail.
  • 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.

    • In 1966, a proposal was considered to construct a SAFEGE-type monorail in the City of Manchester. The 16-mile (26 km) line was planned to link Manchester Airport with the city and suburbs, with an underground tunnel under the city centre, but the scheme was abandoned due to cost. The city eventually developed its own light rail network, Manchester Metrolink.
