Bangabandhu bridge over the River Jamuna.

BANGLADESH: A Railweight in-motion weighing system has been installed to protect the Bangabandhu bridge over the River Jamuna in Bangladesh.

Weight limits were imposed on freight trains crossing the 4·8 km road and rail bridge after cracks appeared, but manual inspection of the 17 trains/day proved time consuming and potentially inaccurate.

The Weighline system can weigh trains moving at up to 80 km/h with an accuracy of +/- 0·25%, enabling overweight trains to be prevented from crossing until they are brought with permitted tolerances.

The system can accommodate both metre and broad gauge trains, with the TSR4000 digital indicator and I-Line PC software recording and displaying data for each train and individual wagons.
