A new rail yard was observed on the Hanoi/Lao Cai Rail Line, 3.5 nm
southeast of the junction of the Hanoi/Lao Cai and Hanoi/bong Dang Rail
Lines. The yard is approximately 550 yards long and seven tracks wide and
is presently empty. Poor quality of the photography precluded determining
the gauge of the track.

Completed Turning Wye at Yen Vien

21 05N - 105 55E, WJ 959321
: JOG (A) 1501, NF 48-11
A newly completed turning wye has been observed 0.4 nm northeast of
the Yen Vien Railroad Classification Yard The turning 25X1
wye was first noted under construction in Report No. 23.
The radius of curvature of the wye as previously determined is
approximately 720 feet. This is the approximate radius of curvature of
standard gauge turning wye located in China. However, the gauge of the
track cannot be determined due to the quality of the photography.
The completion of this probable standard gauge turning wye and the new
rail yard (Figure 7) near Yen Vien, along with the discovery of the new
rail yard (Figure 3) on the Lao Cai Rail Line, establishes the probability
that standard gauge track has been, or very soon will be, laid from
Ping Hsiang to the Hanoi vicinity by at least one of two alternate routes.
One is the direct route along the Hanoi/bong Dang Rail Line. The other is
from Ping Hsiang to Kep, then west to Thai Nguyen, south to Nguyen The, and
finally southeast to Hanoi. This would provide a direct link between Hanoi
and the Chinese standard gauge rail system and eliminate the need of
transloading material between standard and meter gauge cars at the border.

A new rail siding under construction is located 5.5 nm southeast of
Thai Nguyen on the Thai Nguyen Rail Line. The siding consists of three
spurs, two with a single track and one with double tracks. The siding
