VIA THE WASHINGTON POST:
A 14-car train showed up on the Orange Line Monday morning, pulling into New Carrollton Station, according to a Metro press release. Officials said in the statement that an eight-car train that was about to enter service coupled with a six-car train that was stored behind it at the New Carrollton rail yard.
The incident happened about 5:40 a.m. Customers began to board the train, but “were immediately asked to disembark,” and boarded another train, the statement said.
Offcials said employees in the rail yard spotted the 14-car train and alerted the train operator, who removed the train from service. The train operator was removed from service and taken for drug and alcohol testing, which is standard procedure, Metro said.
In July, a train operator delivered a 10-car train to the Greenbelt Metro station. That train actually entered service and stopped at several stations before a rider notified the operator of the problem.
