VINH/DONG HOI RAIL LINE, NORTH VIETNAM
1809N 10543E
1. SIGNIFICANCE:
THIS BRIEFING BOARD DEPICTS THE SERVICEABILITY OF A RAILROAD
BRIDGE BY-PASS AND ITS ASSOCIATED CABLE BRIDGE.
2. LOCATION:
THE RAILROAD CABLE BRIDGE IS LOCATED AT THE SITE OF THE DONG BAI
THE NORTH VIETNAMESE ARE NOW RESTORING DAMAGED BRIDGES ALONG
CRITICAL LINES OF COMMUNICATION BY INSTALLING DECK-TYPE CABLE CROSSINGS
WITH REMOVABLE PLANKS. THIS UNIQUE METHOD OF REPAIR WAS ONLY GRADUALLY
ADOPTED, BUT ITS WIDESPREAD USE SUGGESTS THAT IT WILL BE THE STANDARD
PROCESS BECAUSE BRIDGES BECOME LESS VULNERABLE TO AIR STRIKES.
STEEL CABLE RATHER THAN FIBER CORDAGE IS APPARENTLY BEING EMPLOYED.
ALL INDICATIONS POINT TO THE USE OF A STEEL-WIRE PRODUCT, SOME OF WHICH
HAS COME FROM JAPAN. THE CARGO OF THE SOVIET FREIGHTER CHELYABINSK
WHICH ARRIVED IN HAI PHONG ON 25 AUGUST AFTER CALLING AT JAPANESE PORTS
INCLUDED A LARGE AMOUNT OF WIRE ROPE AS WELL AS SMALLER SIZES OF
GALVANIZED STEEL WIRE.
NGA review(s) completed.
