P.I. NOTES 21/66
"PI NOTES" was not issued for the week of 21 January 1966. This issue
covers a 2-week period.
IAD DEVELOPMENTS
During the final quarter of calendar-year 1965, IAD received 73
requirements from the DDP and completed 74. This effort required 28%
of the total PI man-hours expended by the Division during that period.
IAD PI Course No. 1-66 is tentatively scheduled for presentation
during the period 28 February - 25 March, with 12 IAD PI trainees.
IAD has recently received a prototype Rapid Interpretation Printer -
Processor for evaluation and operational testing. The prototype was built
25X1A by in response to a Division need for a rapid-access,
positive-to-positive contact printer. The unit has a capability to
produce film base, duplicate positives with a resolution of approximately
200 lines/mm. The prototype was built at a cost of but it is
anticipated that production units will cost in the vicinity of

NORTH VIETNAM
The northern segment of the meter-gauge Vinh-Dong Hoi Rail line
was reconstructed by the North Vietnamese during 1963-1965. The rail
line has been successfully interdicted since American airstrikes commenced
in North Vietnam, but photographic evidence indicates that segments of the
northern operable portion of the line continued to be used, probably by

activity was also noted at the Trai Hoi Railroad Bridge, (18-21N 105-37E)
one of the 2 major unserviceable bridges remaining on the operable segment
of the rail line. This segment may be of great logistical importance to
the North Vietnamese, as it provides a direct rail route between the Vinh
area and Route 15. The latter route is the major motorable road into the
Laos Panhandle area, via Mu Gia Pass. (CONFIDENTIAL)
SOUTH VIETNAM
A continuing detailed photographic analysis of northeastern Cambodia
andadjoining areas in Kontum Province, South Vietnam, has revealed 7
probable insurgent bivouac areas interconnected by a series of concealed,
well-used trails located approximately 4.5 NM east of the Cambodian Border.
Strategic Route 14 is located approximately 27 NM to the east.
Although analysis is only preliminary, a very definite similarity
exists between the bivouac areas found in Kontum Province and additional
ones observed in adjoining northeastern Cambodia and southeastern Laos.
Photographic analysis of this border area has been delayed due to the
dense rail forest-type vegetation that predominates in mountain and hill
25X9 areas. (CONFIDENTIAL/NO FOREIGN DISSEM
