Don't get excited. They said we'd be rid of those four-car trains by last December.
Metrorail Adding 24 Rail Cars
To accommodate higher ridership during Cherry Blossom activities, Metro is adding 24 rail cars to its weekday morning and afternoon peak service starting Monday, April 2. These 24 rail cars will allow Metro to initiate eight-car trains on the Red and Green lines and to expand eight-car train service on the Orange Line during the afternoon peak period. Metro will convert one four-car train to a six-car train on the Yellow Line, and convert two four-car Blue Line trains to six-car trains. These added cars will remain in service after the festival.
There is, however, one important and fundamental piece of advice for anyone visiting the DC area:
Visitors should avoid traveling during the peak commuter periods from 5:30 to 9:30 a.m. and 3 to 7 p.m., and are strongly encouraged to avoid traveling Metrorail between 4 and 6 p.m. at the height of the afternoon peak period.Metrorail doesn't have the capacity to handle commuters on a normal day, there certainly isn't room for tourists.
