A computer issue that occurred Saturday afternoon forced all Metro trains to halt service on all lines for about an hour.
The issue occurred shortly after 2 p.m. and affected WMATA's ability to see where the trains were located in the system. As a result, trains were taken to the nearest station, and were held until service was restored. According to WMATA, service was restored around 2:50 p.m.
