Pyongyang Railroad Locomotive Manufacturing and Rolling Stock Repair Plant
produces and probably repairs electric locomotives and passenger cars. The
plant probably produces most of the parts needed for these operations.
Electric locomotives and passenger cars have been identified on photography
in the production area of the plant. We have not been able to determine
the production rate of locomotives or passenger cars from photography.
The plant contains two final assembly buildings, a final assembly building
with a subassembly section, two final checkout buildings, two probable foundries,
a forge shop, a probable fabrication complex, two rail transversers, and numerous
storage, support and administration facilities. In December 1962, the date of
the earliest photography used in this report, the plant was complete. Since
that time only a few minor support buildings have been added. An unidentified
building was under construction when the plant was last seen in March 1971.
The plant has been active on all photographic coverage from December 1962 to
March 1971.
This report includes a photograph of the plant, describes the facilities,
discusses operational functions and production activity, and lists the type
and number of rolling stack observed in the production area.

Pyongyang Railroad Locomotive Manufacturing and Rolling Stock Fep,3ir
Plant is located in the northeast section of Pyongyang (see Figure 1). It
25X1
25X1
is adjacent to Pyongyang Railroad Classification YARDs Sopyangyana 25X1
and 6 nautical miles west-northwest of Pyongyang Airfield E, 25X1
Another rolling stock repair facility which is located 1,000 feet
wewtof the plant may be associated, but it is outside the plant perimeeter.
According to a US Defense Department report, the Japanese built a locomotive
repair facility at this site before the end of World War II. 1/ It was reportedly
damaged during the Korean War and the present plant was built between 1055 and
1957.
Physical Features
The Pyongyang Railroad Locomotive and Rolling Stock Repair Pll-mnl is
enclosed within a walled area approximately 3,000 by 1,000 feet and
about 73 acres. It is road and rail served (see Figure 2).
The main production facilities are two final assembly buildings, one final
assembly building with a subassembly section, two final checkout buildings,
two probable foundries, a forge shop, a probable wheel and axle shop, and a
fabrication complex containing four unidentified buildings and a prolucts
storage yard. Other facilities in the plant include a paint shop, a probable
steam plant, a probable producer gas plant, ten workshops, two probable work-
shops, and several other storage and support buildings. The plant also has
three crane-served material storage yards and two rail transversers.
In December 1962, the date of the earliest photography used in this report,
the plant was complete. Only a few minor support buildings have been added since
that time. Construction of an unidentified building (Item 18) started between
April and November 1970 and it was in an early stage of construction when the
plant was last seen in March 1971.

Operational Functions
This plant produces and probably repairs electric locomotives and
passenger cars. Most of the parts needed for these operations are probably
produced in the plant since it has a forge shop, a probable foundry, a
probable fabrication complex, and several workshops. There are separate
final assembly buildings and final checkout buildings for the locomotives
(Item 23 and 24, Figure 2) and the passenger cars (Item 12 and 19). The
facilities believed to be primarily involved in repair of locomotives and
passenger cars are one of the final assembly buildinns (Item 21), the
probable wheel and axle shop (Item 10), and the paint shop (Item 3). The
two rail transversers are for moving heavy parts, subassemblies, or partially
completed equipment from one building to another or from one bay to another
in the same building.
Production Activity
This plant has been active on all photonraphic coverage from December
1962 through March 1971. It has not been possible to determine the
production rate of either locomotives or passenger cars from photography.
Poor-quality coverage precluded an accurate count of the rolling stock
present before February 1968. Since that time the coverage has not been frequenf
enough to determine whether the rolling stock was newly manufactured or repaired.
Table 1 lists the number of locomotives and passenger cars observed
in the production area of the plant on coverages from February 1968 to
March 1971. It does not include the rolling stock seen in the holding
yard or on the service tracks in the southern section of the plant. A
variety of cars have been observed in that section, usually numbering
80 to 100, which were probably used to deliver raw materials.
