On September 10, the leader of Binh Tri Thien Railway Joint Stock Company said that after the train derailment incidents when passing through Lang Co station (Phu Loc district, Thua Thien Hue), Vietnam Railway Corporation organized an inspection, analysis, and assessment of the cause.
The inspection showed that the quality of the bridge and road was in accordance with technical standards. The reason for the train derailment was that the carriage had air springs, and when passing over a large-diameter track (Tg 0.15), it would resonate with many unfavorable factors (of the bogie type with a large wheelbase of 2,200mm).
The train passes at low speed, the time the guiding force increases is prolonged, causing the guide wheel to grip the rail and cause derailment.
The leader of Binh Tri Thien Railway Joint Stock Company said that to ensure train safety in the coming time through the above location, the unit proposed not to operate trains, and to move passenger trains with air spring cars (with large wheel axle distance) through the turning direction of Tg 0.15 turntable (N10 turntable at Lang Co station). At the same time, arrange capital to repair and replace Tg 0.15 turntables.
