Abstract : Statistical data on the reliability of 15 radio-relay lines (RRL) totaling 4000 km and having 96 stations with RM-24 type equipment and one 272-km RRL having 21 stations with RTA-24 type equipment is reported; all lines are serving railroads. Equipment failures are responsible for 40-55% of the total number of failures; power-supply failures, for 27-41% strong fadings, for 5-33% . The above figures testify to the 'low reliability' of Soviet railroad-serving RRL's. Steps for enhancing the reliability by various reserving techniques are discussed. (Author)
