Faulty Wiring Needs to be Replaced on All of D.C. Metro's New Subway Cars

"[D.C.] Metro must replace faulty wiring on every single one of its new 7000 Series rail cars in a process that could take a year or longer," reports Max Smith.

That news comes from a recently completed internal review of the WMATA's rail car manufacturing program. Metro has placed 548 of the cars into service since 2012, all of which will need to be taken out of service to have wiring replaced. "The agency expects to receive the last of the 748 cars on order by next summer to replace older cars, although the wiring issues and other problems have delayed deliveries recently," according to Smith.

"Besides the wiring issue, the review found that in May 2016, cars arrived at Metro with an average of 22 issues that needed to be addressed," adds Smith.
