## Abstract

FRA is revising the regulations governing train and locomotive power braking systems to include provisions pertaining to the use and design of two-way end-of-train telemetry devices (two-way EOTs). Two- way EOTs provide locomotive engineers with the capability of initiating an emergency brake application that commences at the rear of the train. These revisions are designed to improve the safety of railroad operations by requiring the use of these devices on a variety of freight trains in accordance with legislation enacted in 1992 and by providing minimum performance and operational standards related to the use and design of two-way EOTs.
