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.

DAUGAVPILS LOCOMOTIVE AND CAR REPAIR PLANT INTRODUCES NEW METHODS -- Riga,
Sovetskaya Latviya, 15 Feb 52
Hydraulic jacks are now used in repairing locomotives at the Daugavpils
Locomotive and Car Repair Plant. 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.
