Another too-long train went into service on the Metrorail system early this morning, and WMATA is once again investigating how it happened. WTOP reports that a 10-car train was able to travel from Branch Avenue to the Waterfront-SEU station before being taken out of service. Five employees have been removed from service for routine drug and alcohol testing as a result of the incident. Back in March, a 14-car train briefly went into service on the Orange Line, though the mistake was caught before it left its first station. more ›

John Catoe's last day on the job as Metro General Manager is this Friday, and incoming Interim GM Richard Sarles has pledged to make safety his number one priority. Looks like Sarles has already got one issue to address: a train operator accidentally took off with a 14-car train on the Orange Line this morning, pulling into the New Carrollton station before noticing the mistake. The extra-long train was the result of an 8-car train having been coupled with a 6-car train that had been stored closely behind it in the New Carrollton Rail Yard, according to Metro. From the release:

The train pulled into the station at about 5:40 a.m. and opened its doors. The few customers who boarded the train were immediately asked to disembark. They boarded another train. more ›

In total, 12 cars were damaged, and Metro says it is still assessing the remaining nine cars to determine if repairs are possible. more ›
