WARNING DEVICES OTHER THAN DETONATORS. TECHNICAL SPECIFICATIONS CONCERNING LUMINOUS TORCHES EMITTING A RED FLAME. WARNING MEANS OTHER THAN DETONATORS

The setting-up of the Specialist Committee B 92 was decided upon by the Control Committee of ORE at its meeting on 13th and 14th October 1964 in order to continue the study initiated by the Specialist Committee B 63 on direct warning systems for trains proceeding to a dangerous point. The first task entrusted to this new Committee was: to make a comparison between the torches now in current use, to derive from this comparison the optimum characteristics to be recommended for the torches. A technical specification for torches could be elaborated after comparisons and tests on torches of several Administrations, viz. the FS, SNCB, SNCF and even the JNR. This specification is discussed in part I of the present report. The second aim was the study of the general problem of warnings by less precarious means than detonators, particularly the study of means which could readily be used for the protection of the adjacent track in the case of derailments. The Committee has elaborated an analysis of "warning devices other than detonators", the results of which are given in the table of part II. The B 92 Committee finally considers that of all the warning means studied those which can be most quickly applied are the means based on telecommunication techniques between motive power units and fixed posts or between motive power units mutally, viz.: wireless connections, induction coupling with switches situated in the track or on posts arranged parallel to the track. Irrespective of the use to be made by the Administrations of these telecommunication means, the Committee B 92 considers it absolutely essential that priority should be given to the study of the problem incurred by the immediate warning of trains proceeding towards an obstacle.
