An analysis by the American Public Transportation Association (APTA) found that progress is being made on installation of Positive Train Control (PTC) technology, leading to the potential of a safer environment.
美国公共交通协会(APTA)研究表明列车主动控制技术（PTC）安装取得新进展，创造更加安全的行车环境。
The complex signaling and communications technology, known as PTC, is meant to be progressed throughout commercial ventures by Dec. 31, 2018, under current law. That includes installation of hardware, acquisition of necessary spectrum for its implementation, completion of employee training on the new technology, testing and a submitted plan for the Secretary of Transportation. Full implementation must be completed no later than Dec. 31, 2020.
列车主动控制技术为复杂的信号及通讯技术。根据现行法律，在2018年12月31日之前，通过商业投资的方式，必须加快安装列车主动控制技术，包括安装硬件，获得必要的频谱以供执行，培训员工如何使用这项新技术，调试技术和向交通部长递交计划书。2020年12月31日之前，必须完成所有技术相关工作。
Jeffrey Knueppel, general manager of the Southeastern Pennsylvania Transit Authority (SEPTA), said that PTC is a critical enhancement for commuter rail safety.
宾夕法尼亚州东南部交通局(SEPTA)总经理杰弗里·克努佩（Jeffrey Knueppel）表示列车主动控制技术极大地提高了通勤列车行车安全。
Though deadlines loom near, the industry has already neared completion on numerous aspects of the change. According to APTA, 91 percent of the spectrum has been acquired, 85 percent of the necessary onboard equipment have been installed, 79 percent of on-track equipment have been established, 78 percent of back-office control systems are ready to go, and 74 percent of employees have completed training. The most serious area remaining is the actual testing of PTC. Only 34 percent of the industry is currently testing or has already completed PTC testing.
截止日期将近之时，通勤列车行业已发生许多变化。美国公共交通协会表示，
频谱的获得、必要车载设备的安装、轨道设备的安装和后台控制设备的安装已分别完成91%、85%、79%、78%。74%的员工已结束技术培训。剩下最重要的部分则是列车主动控制的调试。正在调试或已完成调试的控制系统仅占34%。
“Every year, 30 commuter railroads across America safely carry passengers on 501 million trips,” Paul Skoutelas, APTA president and CEO, said. “With safety as our number one priority, the commuter railroads are making strong and continuous progress in implementing Positive Train Control.”
“每年，美国30条通勤铁路安全运送旅客，发车次数达5.01亿次，”美国公共交通协会主席及执行总裁保罗·斯库特拉斯（Paul Skoutelas）说，“我们把安全放在第一位。通勤铁路在使用列车主动控制系统上取得巨大进步。”
Such implementations come at a time when the industry is also struggling to meet a transit repair backlog of around $90 billion. Implementing PTC will, in and of itself, cost more than $4.1 billion to implement. Since Congress mandated PTC, however, the federal government has provided $272 million in PTC grants. An additional $250 million was made available in May 2018.
在使用此项技术的时候，通勤行业正努力应付积压的大约900亿美元的运输维修费用。此项技术的实施费用将超过41亿美元。然而自国会要求使用列车主动控制系统以来，联邦政府已拨款2.72亿美元。2018年5月份再次拨款2.5亿美元。
