Five years after that collision injured 20 people, records show that 11 safety recommendations have not been carried out. Among those pending: upgrading electronics on all Metro trains to prevent them from rolling back and adding door handles for emergency workers trying to enter a rail car quickly.
Those recommendations, known as corrective action plans, represent just a fraction of the improvements that have languished under a system operated by Metro managers and independent monitors from the Tri-State Oversight Committee. A Washington Post analysis of committee data shows that, as of Nov. 20, more than 100 safety corrections recommended after accidents, other incidents and audits were listed as not completed.
