Today’s power loss on the Red Line temporarily left 1,000 people with no way to exit trains and many more with no way to get to work. Fortunately, if you were stuck in the system during the delays, there’s a way to get a refund.

Metro spokesman Dan Stessel writes in an email that customers affected by the outage who are interested in a refund should contact the agency’s customer service division. According to Stessel, Metro hasn’t created a blanket policy for refunds on today’s outage. He’s a little cagey on whether you’ll be able to get a refund, writing only that “Customer service is handled on a case by case basis.”

Examiner reporter Kytja Weir tweets that getting a refund from Metro is much easier if you used a SmarTrip, since that means they have an electronic record proving that you took the Red Line. If you were held up by the outage and used a SmarTrip, there’s no reason not to get your money back—-and show Metro General Manager Richard Sarles that these hours-long outages aren’t acceptable.
