1. Railroad Construction, Thanh Hoa/Vinh Rail Line, North Vietnam
A railroad by-pass is under construction around the damaged Thien .Link
Dong Railroad Siding on the Thanh Hoa/Vinh Rail Line.
The by-pass railbed extends east from the main line at UTM WG746804, then
south to rejoin the main line at UTM WG745798. A rail spur under construc-
tion extends east from the by-pass at UTM WG7468ol to the probable site of
a water-to-rail transshipment point on the southeast bank of the Huang
Giang (river) at UTM WG752802. Some ties, but no rails, have been laid on
the by-pass and the spur (Figure 1). An additional rail spur in the early
stage of construction extends northwest from the main line at UTM WG746808
to approximately UTM WG737813.
