I like working in Washington, and I find it a pleasure to walk along 19th Street in the morning from the Dupont Circle Metro to my office on M Street. But the scenery looks different when the south exit escalator at Dupont Circle Metro Station doesn't work.

Unfortunately, this happens often, and I face 146 steps to be climbed slowly. Sometimes I must stop to rest, and when I appear at the surface of the lovely 19th Street I am overheated. On those days I hate my long skirt and high heels.

Who is responsible for a proper operation of this Metro station? Maybe I could arrange a date with that person so that we could share the pleasure of this morning exercise of climbing 146 stairs.

"Link to the Future" [Metro, Sept. 18] erroneously depicts Metro's erstwhile Green Line shortcut in two ways. First, the shortcut did not consist of commuters north of Fort Totten switching from the Green Line to the Red Line and then back to the Green Line to get to southeast downtown. Rather, the shortcut ran Green Line trains directly downtown, so that during weekday rush hours, only a single transfer was necessary -- at Gallery Place.

The other inaccuracy is that the Green Line shortcut was much hated. Some Red Line commuters whose trains were occasionally delayed may have disliked the shortcut, but the shortcut was an excellent example of Metro being responsive to its customers' needs. Before Metro instituted the shortcut, hundreds of Green Line commuters had to transfer at Fort Totten and crowd onto Red Line trains. The shortcut greatly improved that situation, and for several years it served Green Line rush-hour commuters well.
