RESEARCH TO ASSIST THE FLOW OF FREIGHT TRAIN TRAFFIC THROUGH THE GAGNY RAILWAY COMPLEX

The Gagny railway complex is situated on a line known as the "Outer Ring" encircling the Paris Region. It consists of a double track triangle linking together three SNCF Networks (North, East, South-East); each of the three junctions which form the points of the triangle is linked to either Bobigny, Vaires or Valenton stations situated at distance from the triangle varying from six to sixteen kilometres. Traffic over this railway complex largely consists of freight trains and involves 300 movements daily, with maximum peaks of 20 movements an hour. Since switching and crossing operations take place at the same level, many paths are incompatible with each other, and at times of heavy traffic this results in train delays which are liable to multiply and react unfavorably on the adjacent stations. It should be noted that the trains arrive at the triangle practically at random as far as the signalman responsible for obtaining the paths is concerned; in other words, the latter is unable to rectify conflicting incompatible movements merely by proceeding according to a prearranged plan. Thus conditions always resemble a position where it is constantly necessary to operate under conditions of disruption. The aim was to allow more traffic to pass over the triangle, while reducing the difficulties likely to arise therefrom, especially delays to trains.
