The morning commute on Metro's Red Line could be even slower than usual due to a track problem at the Van Ness-UDC station.
Metro said alternative routes include Metrobus numbers N8, 31, 32, 36, L1, L2 and L4.
It was not immediately known how severe the track problem was or how long delays would continue.
UPDATE: Metro said the situation was resolved at about 6:45 a.m., but some delays are possible.
