DATE OF INFORMATION 1951 - 1952 DATE DIST. -2 ?dui952 SUPPLEMENT TO REPORT NO. SOVIET RAILROADS GET NEW EQUIPMENT; ftEMS PRODUCTION METHODS INTRODUCED RADIOS BEING INSTALLED ON LOCOMOTIVES -- Leningradskaya Pravda, 19 Feb 52 Preparations have started fcr the installation of radio sets on ir-.omotives of the Tashkent Railroad Oystew. Teletype systems are now in operation,?C the Tashkent-Freight, Arys', and Ursat'yevskaya stations to relay information'con- cerning the type of freight which will arrive at these stations. INTRODUCE AUTOMATIC BLOCKING AND TRAIN STOPS ON RAILROADS -- Moscow, Gudok, 3 Jan 52 Many rail thoroughfares. are being equipped with automatic block systems and automatic train.stopa. In addition, the most modern electrical centralized switch- ing is being introduced and radio communications between the locomotive engineer, the station, and train dispatchers are being expanded widely. In addition to the large number of schools, hospitals, and playgrounds, ap- proximately 3.5 million square meters of living quarters have been built for railroad workers during the postwar years. SELF-CLEARING DUMP CARS PRODUCED FOR KUYBYSHEVGIDROSTROY -- Kist ? v, Sovetskaya Moldaviya, 15 Feb 52 Kaliningrad ca: builders have built self-clearing 50-ton dump care for Kuy- byshevgidrostroy (Organization for the Construction of the Kuyby...,ev Hydroelectric Station). The cars are both reliable and economical in operation. While it takes between 150 and 200 persons at least an hour to unload 1,000 tons from conventional type rolling stock, the same amount of tonnage can be unloaded from these dump care by one. man in 3-4 minutes.

The electrical motor winding is now dried in special lamp-drying cabinets and, as a result of this method, the paver plant conserved 61,000 kilowatt-hours in 19;1. The steam used by forging ham- mers was previously released into the air, while now it is used to heat the blacksmith, boiler, and other shops. This conversion of steam save.i the plant 131 tons of coal during the 1951 winter season. LIMIT USE OF METAL -- Minsk, Sovetskaya Belorussiya, 13 Feb 52 Rigid restrictions on the use of metal have been established at the Brest- Vostochnyy Locomotive Depot of the Minsk Railroad System, and worke*s are striving to save both ferrous and light metals. Waste metal, which was for- merly sent to the.scrap heap, is now used as raw stock for the production of such items as cotter keys, blow-out grates, journal box covers, washers, and other parts. It takes 12 kilograms of bronze to produce one bv.,hing. Old bushings are no longer thrown into the scrap heap as junk, but are econditioned and reused. Grease repl'ced oil as the lubricant in piston rod bearings. This extended the life of the bearings and saved light metals. Approximately 16 kilograms of light metal and 60 kilograms of ferrous metal are saved on each locomotive repaired. CAST IRON COLD WELDED BY NAZAROV METHOD -- Moscow, Gudok, 22 Dec 51 According to information of the Main Administration of Car Managements, 25 railroad systems use the Nazarov cold-weld method in welding cast iron. The method, developed by a welder named Nazarov, is used in repairing horizontal boring mills, journal boxes, bearings and other car parts, locomotive cylinders, and superheater receptacles. In cold welding, the welding is done not by one electrode but by a bundle. of copper and steel electrodes which are used at the same time. By using these electrodes simultaneously, the arc changes from one electrode to another, the high temperature created by the arc is moderated, and the heat is distributed over a wider space. As a result, the basic metal melts and fuses together much more slowly and the structure of the cast iron is not destroyed. This is a very important factor in welding cast iron. The molten metal fuses much better because of the difference in the characteristics of copper and steel. The use of coated electrodes permits the formation of a lag which protects the joint from oxidation. Cold welding is not developed more widely because of the lack of special- quality electrodes. Although it is successful, much remains to be done to ex- pand this technological prnness. No method has yet been found to weld locomotive cylinders in a vertical position.
