THE "COMBINED SYSTEM": A NEW SYSTEM FOR IMPROVING THE PROBLEM OF SIGNAL REPETITION ON LOCOMOTIVES

This paper deals with the problem of cab signalling and, more specifically, the choice of the most appropriate system in view of the extension of cab signalling over the entire network. After recapitulating the main characteristics of the two existing systems -- continuous and discontinuous -- the author demonstrates how it is possible to benefit from the advantages of both systems. While the ground installations may be either continuous or discontinuous over the network as a whole, the cabs are being equipped with combined type equipment, to function with either system according to the ground installations on the line in question and the required safety margin.
