THE MODERNISATION OF SIGNALLING AND TELECOMMUNICATIONS EQUIPMENT ON THE PARIS-MULHOUSE LINE (GRETZ-BELFORT SECTION)
LA MODERNISATION DES INSTALLATIONS DE SECURITE ET DE TELECOMMUNICATIONS DE LA LIGNE PARIS-MULHOUSE (SECTION GRETZ-BELFORT)
Modernization of signaling equipment between Gretz and Belfort (404 km) became necessary because the track circuits had to be adapted so that trains hauled by diesel locomotives could be heated electrically. This resulted in replacement of obsolete block signals by automatic color-light signaling which also enabled speed limits to be raised above 140 km/h. The engineering and modifications involved are described. Telecommunications equipment has been modernized at the same time by using trenches dug for the signal cables. A table shows the cost and return on investment.
