WASHINGTON — The evening metro commute will be a scramble, just as the morning trip was.  

While Monday's smoke incident at L'Enfant Plaza is still under investigation by the National Transportation Safety Board, rail service will be both modified and reduced.  Here is Metro's latest press release, issued around 5 pm Tuesday evening:  

Metrorail service information for Tuesday, January 13

For the evening rush hour, Metro service continues to operate in the same configuration as it has throughout the day. Specifically, Yellow Line service has been replaced with additional Blue Line trains that are running between Huntington and Largo. In addition, regular Blue Line service continues to operate between Franconia-Springfield and Largo. Combined, these two service patterns result in Blue Line trains every 6 minutes during the rush hour at all stations along the route, except Franconia-Springfield, Van Dorn St, Huntington and Eisenhower Ave, where trains will run every 12 minutes.

Metro will continue to offer free shuttle bus service — as an alternate travel option — between L'Enfant Plaza and Pentagon stations until 8 p.m. tonight.

As of 3:30 p.m. 21 passengers remain hospitalized — 14 at Washington Hospital Center and 7 at George Washington University Hospital. All patients who were at Howard University Hospital have been treated and released.

Additionally, Metro is confirming the identify of the passenger who died as Carol Inman Glover, 61, of Alexandria, Va.

The NTSB investigation remains ongoing. Pursuant to 49 C.F.R. Part 831 (NTSB Accident/Investigation Procedures), the NTSB is the sole source of public information regarding the progress of an accident investigation.

The train involved in yesterday's incident remains in its location just outside of L'Enfant Plaza Station. Metro plans to move the train and advance repair work later tonight.

Additional service information will be provided as it becomes available.
