This describes the DC Metro's Green line as it weaves at high speeds under the most spectacular, and most violent view of the city (13 and Clifton Sts, NW, but don't step out of the car). Taking the Red Line to the OB is usually quickest, but today, Red Liners were stacked up at every signal. Therefore, it was Green Time. I can't believe I'm doing this is such little time, but Fort Totten- Lower platform is half on and half under the cliff. Train speeds up to a 65mph cruise to serve Petworth and Columbia Heights, cut and cover resumes south of Shaw in the 1991 section. Pass the lower level of Gallery Place, under the mall and poping up in the HUD area of L'enfant plaza, a '60's urban renewal area. At the south end of the station, a set of escalators lead to nowhere, perhaps a future entrance. Get on OB, lower level. Note the glass-paneled escalators.
Sorry for not having enought time!
