Metro-North issued a report Wednesday outlining safety improvements it has made over the past 100 days.
The agency's safety record has been in the spotlight since a deadly derailment in the Bronx in December.
Metro-North says since then, it implemented 21 changes and plans to complete or pursue 11 more.
They include new track inspection and maintenance practices, alerts and video cameras in engineers' cabs, increased safety training for employees and a confidential reporting system for safety issues.
The report and upgrades include recommendations from the Federal Railroad Administration.
The Metropolitan Transportation Authority and the National Transportation Safety Board have yet to submit their guidelines.
