今年3月1日在美国西弗吉尼亚亨丁顿—宾顿间250Km 的山区铁路上蒸汽机车复活试运。由美国柴西·俄亥俄铁路的4-8-4型614号蒸汽机车牵引煤炭列车每周开行三对。这是目前开发现代蒸汽机车“ACE 3000型”的美国煤炭企业公司(ACE)进行的蒸汽牵引试运。目的是为了取得与以后试制成的“ACE3000型”做性能试验对比用的基础资料。将取代内燃机车的“ACE 3000型”,轮周功率为3000马力,煤炭、给水、风的供应均由微处理机控制,由一人驾驶,试制样机预定在今年内开始制造。
On March 1 this year, a steam locomotive was re-commissioned on a 250-kilometer mountain railway between Huntington and Brampton, West Virginia. Coal train driven by steam locomotive No. 4-8-4, Type 614 steam locomotive, operated by the US Chissie-Ohio Railroad runs for three times a week. This is a steam-traded trial run by the American Coal Enterprise Company (ACE), which is currently developing the ACE 3000 steam locomotive. The purpose is to obtain with the trial version of the “ACE3000” to do the basic performance test data. Will replace the “ACE 3000” diesel locomotive, the weekly power of 3000 horsepower, the supply of coal, water supply, wind are controlled by the microprocessor, driven by one person, trial prototype is scheduled to begin manufacturing this year.
