Metro's failure to keep running trains an extra hour as promised during the seasonal time change was due to a human error in the control center that day, according to Metro.
The agency had told riders it would stay open an hour later, as it typically does, when clocks changed on Nov. 4 from daylight saving time to standard time. But then it actually closed the system at 3 a.m. Eastern Daylight Time, meaning 2 a.m. Eastern Standard Time, stranding riders counting on the extra hour.
The agency apologized for the mistake in the subsequent days but had not explained what went wrong.
General Manager Richard Sarles told The Washington Examiner on Thursday that the agency had intended to run trains an hour longer but a communication problem happened in the control center.
When asked if anyone faced any discipline for the mistake that stranded an untold number of riders, Sarles said that everyone makes mistakes.
"The person will never ever make that mistake again," he said.
