Summary

This document provides the public with notice that, on August 6, 2026, the Belt Railway Company of Chicago (BRC) submitted a request for amendment (RFA) to its FRA-certified positive train control safety plan (PTCSP) to perform necessary maintenance and optimization of its operational technology network during September and October 2026. To complete this maintenance, BRC is requesting four planned windows during which work will be performed on the network infrastructure, and during which unplanned positive train control (PTC) system outages may occur. As this RFA involves a request for FRA's approval of proposed material modifications to an FRA-certified PTC system, FRA is publishing this notice and inviting public comment on BRC's RFA to its PTCSP.
