Recent photography reveals new North Vietnamese railroad construction
between the Thai-nguyen (21 "AN - 105 52E) and Kep (21 24N - 106 17E)
areas.
A roadbed in the very early stages of construction, extends from
the existing rail line between the Thai-nguyen Iron and Steel Combine
and the Thai-nguyen Iron Ore Processing Plant
at 21 31N - 105 56E southeastward for 22 nm to a point one nm
N. W. of the Hanoi/Dong-Dang Rail Line at 21 25N - 106 17E. This
railroad when completed will provide a more direct route between China
and the Thai Nguyen Iron-Steel Combine thereby tying the economies of
the two countries more closely together.
The roadbed is being constructed on level terrain in the transition
zone between the cultivated riceland area to the south and the wooded
hills area to the north. The railroad will have gentle curves and light
gradients when completed.
Two new rail yards are under construction just north of the existing
Kep Rail Yard on the Hanoi/Dong-Dang Rail Line at 21 24N - 106 17E (Figure
A. Yard I (Figure 3) will probably be used az a freight holding
yard. It consists of a through main line and a. completed turning
wye with curvature radadi of 800 feet and 48o feet. Two other
tracks are under construction in the yard and there is space for 5
additional tracks. A probable watering and fueling facility is
under construction in the yard.
B. Yard 2 (Figure 3) will probably be used for classification.
It consists of two completed tracks and 6 tracks under construction.
There is space for approximately 5 additional tracks.
As of construction was not sufficiently advanced
to determine the capacity of either of these yards.
A 30 nm segment of the Hanoi/Dong-Dang Rail Line from Kep northward
to 21 45N - 106 44E was studied. Within this area several curves of the

existing railroad were being actively re-aligned (Figure 6). This railroad
realignment does not appear to relate to the standard gauge roadbed
construction activity which was discontinued by the North Vietnamese
late in 1961 or early 1962 (Figure 7).
Although the radai of the turning wye in railroad yard No. 1 is
comparable in size to the standard gauge turning wye at Ping-hsiang,
there is no further evidence to indicate that the North Vietnamese
are starting to convert the Hanoi/Dong-Dang Rail Line from meter to
standard gauge. The construction of the two rail yards and straightening
of curves on the Hanoi/Dong-Dang Rail Line appears only to be concerned
with increasing the traffic handling capability of the rail line at this
time.
