2008年，位于怀俄明州粉河盆地的黑雷矿山（美国最大的煤矿综合体，由位于密苏里州圣路易斯的Arch Arch Inc.拥有）计划安装新的大型输送管，将煤炭转移至装载火车的筒仓。当时BNSF铁路公司的工程副总裁David Freeman得知该矿山的计划时，他想确保铁路投入了。该矿山计划租用一台270万磅的起重机，将260英尺长，500,000磅重的输送管吊到空中150英尺，并将其放置在塔架上。复杂的安装过程将使管道悬挂在3条轨道上，每天有80列BNSF和联合太平洋铁路公司的列车通过，将近100万吨的煤炭运送到整个中西部和东海岸的发电厂。总体而言，美国运输的煤炭的三分之一将在260英尺长的管下通过铁轨。弗里曼的职责是审查矿山的计划并确保密切协调，以最大程度地减少对BNSF客户的服务中断。因此，在计划于2008年5月的星期六执行起重机的微妙操纵时，BNSF和联合太平洋公司停止了交通。弗里曼还派遣了两名维修人员和四台大型拖拉机前往现场，以在需要时提供帮助。他在得克萨斯州沃思堡的BNSF总部拥有一支团队。 BNSF的准备有所作为。下午12:30那个星期六，弗里曼接到了一个电话。弗里曼回忆说：“他们把管子丢在了轨道上。” 1吊重物的起重机倒塌了，巨大的管子直接掉落在所有三个轨道上。2事件中三名建筑工人受伤。阅读全文

IN 2008, the Black Thunder mine in Wyoming’s Powder River Basin — the largest coal mining complex in the United States, owned by St. Louis, Missouri-based Arch Coal Inc. — planned to install a massive new conveyer tube to move coal to a silo for loading trains. When David Freeman, vice president of engineering at BNSF Railway Co. at the time, heard of the mine’s plans, he wanted to be sure the railroad had input. The mine planned to hire a 2.7-million-pound crane to hoist the 260-foot long, 500,000-pound conveyer tube 150 feet into the air and place it on pylons. The intri- cate installation process would suspend the tube over three tracks on which 80 BNSF and Union Pacific Railroad Co. trains traveled every day, carrying almost 1 million tons of coal to fuel power plants all across the Midwest and the East Coast. Overall, one-third of America’s transported coal would pass on the rails under that 260-foot long tube.Freeman’s role was to review the mine’s plans and ensure close coordination to minimize service interruptions to BNSF’s customers. Thus, BNSF and Union Pacific halted traffic while the crane was scheduled to perform its delicate maneuver on a Saturday in May 2008. Freeman also sent two repair crews with four large tractors to the site to assist if needed. And he had a team on notice at BNSF’s headquarters in Fort Worth, Texas. BNSF’s readiness made a difference. At 12:30 p.m. that Sat- urday, Freeman got a phone call. “They dropped the tube on the tracks,” Freeman recalled a stunned onsite worker saying.1 The crane doing the heavy lifting had collapsed, and the giant tube had fallen directly across all three tracks.2 Three construction workers were injured in the incident.Read Full Article
