Three Metro workers disciplined for 10-car Green Line train

Three Metro employees have been disciplined for allowing a 10-car train — two cars too many — to run on the Green Line last week.

The operator of the train was suspended without pay for 13 days, while the platform supervisor earned a five-day suspension and an interlocking operator who oversees train movements in rail yards was reassigned to a new job, Metro spokesman Steven Taubenkibel said Thursday.
