美國通報列車主動控製係統；擬議規則

編號：G/TBT/N/USA/480/Add.2

標題：正向列車控製係統

機構：聯邦鐵路管理局（FRA）、運輸部（DOT）

行動：最後規則

概述：FRA正在修訂其關(guan) 於(yu) 列車主動控製（PTC）係統變更和PTC係統性能報告的規定。首先，認識到鐵路行業(ye) 打算加強FRA認證的PTC係統，以繼續改善鐵路安全和PTC技術的可靠性和可操作性，FRA正在修改程序，根據該程序，在對PTC安全計劃（PTCSP）和FRA認證的PTC係統進行某些更改之前，主鐵路必須向FRA提交修改請求（RFA）。第二，為(wei) 了實現更有效的聯邦鐵路管理局監督，這項最終規則：通過將頻率從(cong) 每年增加到兩(liang) 年，擴大現有的報告要求；擴大報告要求，包括積極的績效相關(guan) 信息，包括技術對鐵路安全的積極影響，而不僅(jin) 僅(jin) 是故障相關(guan) 信息；並要求主辦鐵路公司使用新的標準化報告表格。

該最終規則於(yu) 2021年8月26日生效。

TITLE: Positive Train Control Systems

AGENCY: Federal Railroad Administration (FRA), Department of Transportation (DOT)

ACTION: Final rule

SUMMARY: FRA is revising its regulations governing changes to positive train control (PTC) systems and reporting on PTC system performance. First, recognizing that the railroad industry intends to enhance FRA- certified PTC systems to continue improving rail safety and PTC technology's reliability and operability, FRA is modifying the process by which a host railroad must submit a request for amendment (RFA) to FRA before making certain changes to its PTC Safety Plan (PTCSP) and FRA-certified PTC system. Second, to enable more effective FRA oversight, this final rule: Expands an existing reporting requirement by increasing the frequency from annual to biannual; broadens the reporting requirement to encompass positive performance-related information, including about the technology's positive impact on rail safety, not just failure-related information; and requires host railroads to utilize a new, standardized report form.

This final rule is effective 26 August 2021.
