PREFACE
This report is a summary of selected information on
transportation and infiltration activity in Southeast Asia,
primarily the Laotian Panhandle, as reported by NPIC
during the period indicated on the cover. For a compre-
hensive study of road development in this area prior to
1 April 1966 see NPIC R-110/66, Communist Road Net
Development in the Laotian Panhandle (CONFIDENTIAL/
items are numbered and arranged according to location
from north to south. Annotated maps of varying scales
have been included to assist the reader in locating the items.
Each large-scale map depicts all motorable roads photo-
graphically confirmed by NPIC.
Missions, mission dates, frames, and NPIC cable and
briefing board references are listed after each item, as
appropriate.

1. Dual-gauge Capability, Ha Noi/Ping Hsiang Rail Line
A dual-gauge rail line capability (Figure 1B) presently exists on the
Ha Noi/Ping Hsiang Rail Line between Cao Nung Railroad Bridge at 21-33N
106-29E and Kep Rail Yard at 21-25N 106-17E. Meter gauge rail lines may
be converted to dual-gauge by widening the rail bed and adding a third rail,
permitting utilization of the line by both meter gauge (used in North
Vietnam) and standard gauge (used in China) rail cars. The existence of a
third rail between the Cao Nung Railroad Bridge and China has not been
verified due to a lack of photographic coverage.
25X1 D On photography oJ 'the dual-gauge rail line
was not observed 4.5 nm northeast of Kep at 21-26N 106-21E; however, there
was evidence of construction preparation for the addition of a third rail.
The rail bed had been widened and improved and standard gauge rail ties
had been substituted for the shorter rail ties used for meter gauge lines
(Figure 1C). The third rail was in place 9.5 nm northeast of Kep at
21-30N 106-25E
Construction activity observed south of Kep indicates the probable
extension of the dual-gauge capability to Ha Noi. A work train discharging
ballast was observed at 21-19N 106-15E (Figure 1E) and standard gauge rail
ties were observed at 21-16N 106-10E (Figure 1F) and at 21-20N 106-15E.
Undistributed ballast has been observed piled at numerous places in this
area.
A rail line is under construction between Kep and the Thai Nguyen
Ore Processing Plant rail line (Figure 1A). The junction of this line
with the Ha Noi/Ping Hsiang Rail Line at 21-25N 106-18E (Figure 1D) was
observed on photography and only standard
gauge track was observed in this area.

6. Route 110 Segment Remains Unserviceable
Successive pho ?graphic coverage indicates that Route 110 remained
unserviceable from due to concentrated interdictions at
UTM YB447289. There has been no attempt to repair or by-pass the inter-
dictions. No vehicles have transited the area during this period; however,
a foot trail is observed (Figure 5).
