It seems that drugs are behind WMATA’s latest innovation: the 10 car train. During rush hour on July 31st, a Green Line train operator was alerted by a passenger that his train was trailing two extra cars. Metro platforms are only designed to accommodate 8 car trains, so the additional carriages were never made it into the stations and remained unused. The train made it from Greenbelt to Georgia Ave before being noticed, after which it was taken out of service. The support personnel responsible for staging the train were subjected to drug tests, and one individual tested positive. WMATA is still investigating and has yet to take any disciplinary action. Hooray, Metro!
