The Red Line has apparently gone Red Light.

A station manager at Washington D.C.'s Dupont Circle Metro station has been charged with running a prostitution ring from her post inside the subway station, including arranging trysts with fellow Metro employees.

Sharon Waters, 42, was nabbed in a Metro Transit Police investigation that was responding to tips she had been circulating flyers promoting sex trips to Brazil as a representative of the Blossom Travel Agency. In an undercover sting operation in June, Waters was approached by a Metro policeman posing as an out-of-town businessman who inquired about the flyers.

Waters pulled out a book featuring "numerous nude and sexually explicit pictures of women from Brazil that were available on the trips," according to the affidavit. She also mentioned a sex party in the D.C. area with a $100 cover charge, and gave the businessman her phone number. When contacted later, Waters offered to set the man up with women for sexual encounters.

At a subsequent meeting at the Dupont Circle station, Waters got on the public loudspeaker system to page "Pam," another Metro employee who then offered to engage in sex acts for $200. That woman, Pam Goins, 45, is also being charged. During the conversation between Waters, the undercover cop and Goins, the affidavit said, Goins "made numerous references to different sexual acts she wanted to perform with (the officer) and grabbed his crotch/groin area."

Waters, of Bowie, Maryland, had been a Metro employee since 1990 and was making $56,657 base salary as of 2006. Her husband is also a Metro station manager, reports the D.C. Examiner, though it's not known whether he was involved in the ring.

Hot on the heels of the "D.C. Madam" and the Eliot Spitzer affair, this latest prostitution case may peter out quickly, as a D.C. Superior Court judge has agreed to allow charges to be dropped if Waters successfully completes a rehabilitation program. The four-month, six-hours-a-week "diversion" program, called Angel’s Project Power, is designed to give women arrested for prostitution a second chance. Among the "life skills" classes being taught is entrepreneurship, something Waters and company don't exactly seem to be lacking. 

At the very least, they've given us something new to smile at every time we see the subway's boring "Metro Opens Doors" slogan.
