TRAFFIC CONTROLLER-LOCOMOTIVE COMMUNICATIONS ON THE DOLE-VALLORBE LINE

LIAISON "REGULATEUR-LOCOMOTIVE EN MARCHE" SUR LA LIGNE DOLE-VALLORBE

System described operates with two wires laid along the catenary line supports at locomotive roof height. The locomotives have two aerials which enable communications to be established through the line when the train is stationary, in motion or passing through the tunnels. The traffic controller calls the locomotives by dialing two digits on an automatic telephone set. The electric-train drivers call the traffic controller by pressing a button. The system enables 98 locomotives to be contracted by carrier channel (two frequencies) and three channels can be transmitted on the overhead line.
