Luminous torches for signalling used in Europe and Japan were tested as a part of the task of Specialist Commitee B92. Work is now directed toward warning devices with a range of 2-3 km. A Hertzian torch, which is a transmitter, would emit radio warning signals to a receiving device to be installed in every motive power unit. Another solution would be the installation of transmission and reception devices on the motive power units, connected by inductive coupling through conductors along the railway track. This method is especially advantageous in tunnnels and hilly terrain. Cost comparisons are being made.
