BRITISH company Railweight has installed in-motion train weighing systems on each side of the 4.8km Jamuna River road/rail bridge in Bangladesh. The bridge, opened in 1998 to connect the two parts of Bangladesh's hitherto divided rail network, and is currently used by up to 17 freight trains a day which are subject to a weight restriction to prevent further cracks from forming in the bridge. Up to now, freight trains have had to stop for a lengthy manual inspection, which was not particularly accurate, before being allowed to cross. Now it is possible to weigh trains at up to 80km/h and when travelling on either broad or metre-gauge track.
