2008年，位于懷俄明州粉河盆地的黑雷礦山（美國最大的煤礦綜合體，由位于密蘇里州圣路易斯的Arch Arch Inc.擁有）計劃安裝新的大型輸送管，將煤炭轉移至裝載火車(chē)的筒倉。當時(shí)BNSF鐵路公司的工程副總裁David Freeman得知該礦山的計劃時(shí)，他想確保鐵路投入了。該礦山計劃租用一臺270萬(wàn)磅的起重機，將260英尺長(cháng)，500,000磅重的輸送管吊到空中150英尺，并將其放置在塔架上。復雜的安裝過(guò)程將使管道懸掛在3條軌道上，每天有80列BNSF和聯(lián)合太平洋鐵路公司的列車(chē)通過(guò)，將近100萬(wàn)噸的煤炭運送到整個(gè)中西部和東海岸的發(fā)電廠(chǎng)?？傮w而言，美國運輸的煤炭的三分之一將在260英尺長(cháng)的管下通過(guò)鐵軌。弗里曼的職責是審查礦山的計劃并確保密切協(xié)調，以最大程度地減少對BNSF客戶(hù)的服務(wù)中斷。因此，在計劃于2008年5月的星期六執行起重機的微妙操縱時(shí)，BNSF和聯(lián)合太平洋公司停止了交通。弗里曼還派遣了兩名維修人員和四臺大型拖拉機前往現場(chǎng)，以在需要時(shí)提供幫助。他在得克薩斯州沃思堡的BNSF總部擁有一支團隊。 BNSF的準備有所作為。下午12:30那個(gè)星期六，弗里曼接到了一個(gè)電話(huà)。弗里曼回憶說(shuō)：“他們把管子丟在了軌道上?！?1吊重物的起重機倒塌了，巨大的管子直接掉落在所有三個(gè)軌道上。2事件中三名建筑工人受傷。閱讀全文

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
