WASHINGTON - Metro says it will begin inspecting brakes on all 588 of its escalators starting Friday night. This comes in the wake of an escalator accident at the L’Enfant Plaza station on Saturday that injured six people. A preliminary investigation this week showed that escalator brakes failed in this incident, causing it to speed up and hurl riders to the bottom. Metro says it should take less than a week to complete the inspections. Metro Board and D.C. Council Member Jim Graham sat down with the FOX 5 News at 10 to discuss the inspections and the escalator brake problems.
