What the agency says
On October 28, 2024, FRA published an NPRM proposing to amend certain regulations governing positive train control (PTC) systems. Through oversight and continued engagement with the industry, FRA has found that its existing PTC regulations do not adequately address temporary situations during which PTC technology is not enabled, including after certain initialization failures or in cases where a PTC system needs to be temporarily disabled to facilitate repair, maintenance, infrastructure upgrades, or capital projects. FRA expects PTC systems to be reliable and robust, further reducing the occurrence of initialization failures and outages. The NPRM proposes to establish strict parameters and operating restrictions under which railroads may continue to operate safely in certain necessary scenarios when PTC technology is temporarily not governing rail operations. By this notice, FRA is extending the NPRM's comment period, which will close on December 27, 2024, by 15 days.
