1. Interdictions, Ha Noi/Ping-Hsiang Rail Line, North Vietnam
Three major interdictions are observed on the Ha Noi/Ping-Hsiang
Rail Line. The Cao Nung Railroad Bridge over the Song Hoa
25X1A - at 21-33N 106-29E has been severely damaged by air strikes and is
unserviceable. At least two spans have dropped into the river and the
southern approaches have been interdicted. The railroad by-pass bridge
is also unserviceable because the spans have been removed. Interdictions
25X1A on all tracks have rendered unserviceable the three-track dual-gauge Bac
Le Railroad Yard at 21-30N 106-26E. Obliquity
precludes determination of the damage and gauge of two engines and 30
pieces of rolling stock in the yard. The Dap Cau Railroad and Highway
~5X1A Bridge over the Song Cau at 21-12N 106-05E is unser-
viceable due to air strikes. Since the railroad by-pass bridge around
the Dap Cau bridge is not complete, the rail line is also unserviceable
to through traffic in this area.

2. Standard-gauge Rail Cars, Kep/Thai Nguyen Rail Line Under
Construction, North Vietnam
Standard-gauge track was first observed on the Kep/Thai Nguyen Rail
Line under construction in from its turnout from the Ha Noi/
Ping-Hsiang Rail Line at 21-25N 106-18E (UTM XJ353696) west for 0.5 nm.
This trackage now extends to a bridge under construction at 21-25N
106-16E (UTM XJ315701), a total distance of 2.2 nm. No track has been
laid west of the bridge. Fifteen standard-gauge gondola cars are
observed on this line at UTM WJ352696 (Figure 1) and one standard-gauge
engine and at least 1I3 standard-gauge rail cars are in a three-track rail
yard at the railhead. The presence of these cars on a standard-gauge
rail line determines their gauge. This identification of standard-gauge
rail cars in North Vietnam indicates that dual-gauge track probably
extends northeast to China, but this is photographically confirmed only
from 21-25N 106-17E northeast to 21-37N 106-33E.

;. Railroad Ferry Reconstruction, Ha Noi/Vinh Rail Line, North Vietnam
A railroad ferry is being reconstructed on the Ha Noi/Vinh Rail Line
near the serviceable Thanh Hoa Railroad and Highway Bridge over the Song
Ma at 19-50N 105-48E and at the destroyed Thanh Hoa
Railroad Ferry and Terminal Facilities Ham Rong A 25X1A
three-track rail yard extends from the main line at UTM WG842938 south-
southwest to an open storage area at UTM WG840932. Two railroad ferry
slips are on the northeast bank of the Song Ma (Figure 2). One slip is
probably complete at UTM WG837931, with more than 300 feet of track
extending from it to the rail yard. The second slip is in the early stage
of construction at UTM WG838930, with more than 150 feet of ties without
rails extending from it to the rail yard. Two pile drivers are near the
second slip and several piles have been emplaced. A steam locomotive and
at least 60 pieces of rolling stock are in the rail yard; the open storage
area contains rails, ties, and miscellaneous materials.
Two railroad ferry slips are on the southwest bank of the river. One
slip at U'IM WG836927 is probably complete. The other is in the early stage
of construction at UTM WG835929, with one pile driver and several pilings
nearby. Although no rails or ties have been placed on the approaches of
either slip, they will probably be connected to the Ha Noi/Vinh Rail Line
at UTM WG827931, using a previously existing road as a roadbed.

~+. Activity on the Vinh/Dong Hoi Rail Line, North Vietnam
A. The railroad cable bridge at the destroyed Xom Khe Railroad Bridge
25X1A over the The Net at 17-58N 105-55E has been severely
damaged by air strikes and is unserviceable. Six of the seven A-frame
cable supports and portions of the rail remain, although the south approach
has been destroyed. Construction continues on the railroad by-pass.
B. The railroad cable bridge at the destroyed Kim Lu Xa Railroad
25X1A Bridge over the The Danh at 17-57N 105-57E is complete.
Rails joining the main line now span the river and at least seven A-frame
cable supports have been erected. Two cables have been observed, however,
the present number cannot be determined.
C. The railroad by-pass bridge remains under construction around the
destroyed Thuong Phong Trang Railroad Bridge over the Rao Nay
25X1A - at 17-51+N l06-OOE. Rails extend northeast from the north bank of
the stream at UTM XE065800 for 100 yards. Six A-frame cable supports have
been erected and a T-shaped probable cable anchorage is on each bank. A
probable tramline consisting of two cables spans the stream immediately
west of the destroyed bridge at UTM XE063803.

5. Xom Ca Trang Vehicular Cable Bridges, Route 15, North Vietnam
Three vehicular cable bridges are now located on Route 15 at 17-57N
105-1+8E in the vicinity of Xom Ca Trang. The cable bridge constructed
across the Xom Ca Trang Highway Bridge over the Rao Cai 25X1A
is unserviceable due to air strikes. The northern approach is heavily
interdicted and the northernmost span of the original bridge has been
dropped from the abutment. Since the cables across the cable span appar-
ently remain taut, the northern cable anchorage is possibly intact. The
cable bridge at the Xom Ca Trang Highway Bridge over the Nam Quat - 25X1A
is complete, but apparently unused. The cable anchorages are
now filled and both bridge approaches are serviceable. The previously
observed bridge decking has been removed in a possible reaction to the
bombing of the Rao Cai cable bridge. A second cable bridge over the Nam
Quat at UTM WE859859 consists of a wooden pier in the middle of the river
supporting at least one tautly strung cable. An approach under construc-
tion on the northeast bank and an associated road clearing operation on
the southwest bank are not yet connected to Route 15.

6. Unserviceability and Disuse of Route 96, Laos
25X1 D
An approximately 2.8-nm segment of Route 96 is unserviceable from
UTM YC042240 to YC074233, due to numerous landslides and interdictions
(Figure 3). Additional sections of the road show signs of disuse due
to overgrowth. One such area is immediately west of the unserviceable
Kay Bong Highway Ford on the Dak E Meule at 15-34N
1o6-55E (Figure 3). Annotated on the adjacent map are previously
reported landslide areas, none of which have been observed reopened or
circumvented.

SPECIAL PHOTOGRAPHIC SUPPLEMENT, Ha Noi/Vinh Rail Line, North Vietnam
Photography has revealed a continuing effort by the North Vietnamese
to maintain, improve, and extend the rail service within their country.
This special photographic supplement, like the-two preceding it (Summaries
1.3 and 15), is designed to illustrate this effort. At least 14 railroad
bridge structures between Ha Noi and Vinh have been by-passed or have by-
passes under construction. The first four items discussed below are on
the Ha Noi/Thanh Hoa Rail Line; the remaining 10 are on the Thanh Hoa/Vinh
Rail Line.
A railroad by-pass bridge is under construction east of the service-
able Ninh Binh Railroad and Highway Bridge over the Song Day 25X1A
at 20-15N 105-59E (Figure 4). A railroad ferry is immediately east
of the Ninh Binh bridge at UTM XH032403.
Two railroad by-pass bridges around the destroyed Dong Phong Thuong
Railroad and Highway Bridge over the Song Len at 25X1A
19-58N 105-50E are unserviceable (Figure 5). The Dong Phong Thuong Rail-
road 25X1A
Bridge South over the Song Len is serviceable
1.5 nm southwest of the main bridge at UTM WH863078 (Figure 6).
The Phuong Dinh Railroad Bridge over the Lach Truong 25X1A
25X1A at 19-51N 105-48E is under construction immediately west of the
serviceable Phuon Dinh Railroad and Highway Bridge over the Lach Truong
25X1A (Figure 7).
A railroad ferry is being reconstructed near the serviceable Thanh
Hoa. Railroad and Highway Bridge over the Song Ma at 25X1A
19-50N 105-48E (Item 3).
A railroad by-pass bridge has been constructed around the serviceable
Thien Linh Dong Railroad Bridge over the Hoang Giang at 25X1A
19-43N 105-42E (Figure 8).
A railroad by-pass bridge is under construction west of the service-
able Thinh Lac Railroad Bridge at 19-40N 105-42E 25X1A
(Figure 9).
The Truong Quang Tien Railroad Bridge East has 25X1A
been constructed east of the serviceable Truong Quang Tien Railroad Bridge

1.05-41E. An additional railroad by-pass bridge is under construction at
UTM WG725302 (Figure 14).
A railroad by-pass bridge is under construction east of the service-
able Tu My Railroad Bridge at 18-59N 105-34E (Figure 15).
The Dien Chau Railroad Bridge East over the Song Bang
