Bogie Open Wagon (25T Axle Load) --- The key feature of this variant is carrying capacity of 80 tonnes which is higher by 12.76 % fodue to an enhanced axle load design resulting, additional 535 metric ton material overcharge in a 59 wagons rake in comparison to BOXNHL Rake. Designed with the best ever pay/tare ratio of 4.21. Developed with unique 'Fish Bone Structure' with side stanchions integrated with cross members. Shorter but taller structure design with no doors fully welded construction resulting low maintenance and higher life-span of the wagon. Optimal material selection by using cost effective stainless steel (IRS:M44), on surfaces in contact with coal, which is rust free, have better durability & low maintenance. But the under-frame is fabricated with HSLA steel IS:2062 E450 (Fe570) BR with Cu. This high strength micro alloyed steels have higher yield strength, higher notch toughness, good fatigue properties, excellent weld ability and good formability. These wagons are fitted with twin pipe air-brake system with slack adjuster IRSA:750. Uses LWLH 25T bogie instead of CASNAB-NLC. Type - BOXNS
