The 50 Hz consortium or 50 Hz group , English 50 c / s Group , French Groupement d'Étude d'Électrification Monophasé 50 Hz , later Groupement 50 Hz , was a consortium of European rail vehicle manufacturers , which electrical systems and traction vehicles for manufactured and sold the 25 kV 50 Hz traction power system. The company's registered office was in Zurich .

history

The working group was founded in 1954 on the initiative of the French railway engineer Fernand Nouvion with the aim of marketing the export market for the technology of railway electrification developed in France with a voltage of 25 kV and a frequency of 50 Hz. The working group achieved its first success with the electrification of the Istanbul S-Bahn . This was followed by the Portuguese Railways and export successes to the Soviet Union and China . A particularly large order was the electrification of the Indian railways with 25 kV and 50 Hz. The working group sold equipment parts for over 1000 locomotives to India and was very successful until the mid-1980s.

Manufacturer

The following manufacturers belonged to the working group when it was founded:

• Ateliers de Constructions Electriques de Charleroi (ACEC) from Belgium

• Jeumont from France
• Maschinenfabrik Oerlikon from Switzerland
• Matériel de traction électrique (MTE) from France

Some of the companies listed above later merged with each other. In the 1990s ACEC, AEG, Alsthom, BBC and Siemens were still in the group. BBC left the 50 Hz community after merging with Asea.

scope of delivery

Most of the projects included both fixed systems and traction vehicles and were handled by the consortium as general contractor . By 1975, over 2150 locomotives , multiple units and electrical equipment for multiple units had been delivered. In addition, 600 km of railway lines were electrified and substations with a total output of 330 MVA were delivered. The scope of delivery also included signaling and radio systems as well as remote control devices. The projects were carried out in the following countries:

• Yugoslavia
• South Korea
• People's Republic of China
• Portugal
• India
• Hungary
• Turkey
• Soviet Union
• Costa Rica
• Belgian Congo (now the Democratic Republic of the Congo )
