It’s a busy week for Metro officials and the people who closely watch the region’s transit authority.

General Manager Richard Sarles is scheduled for appearances on Capitol Hill to deal with questions on the transit system’s security and other issues. And Metro’s union wants to hear from riders at a town meeting.

The week kicks off with a Monday evening meeting at the MLK Library that’s an open forum for riders to talk with the leaders of Amalgamated Transit Union Local 689. The union, which represents most Metro workers, wants to create a dialogue between transit riders and employees.

At 10 a.m. Wednesday, Sarles and Metro staffers will lay a wreath at Fort Totten Station to observe the second anniversary of the Red Line crash that killed nine people and injured dozens.

The Metro board is expected on Thursday to pass its fiscal year 2012 budget and the Tri-State Oversight Committee, which monitors Metro , plans to give details on their view of the transit agency’s safety operations.

On Friday, Sarles is expected to testify on Capitol Hill before the House Subcommittee on District of Columbia, Census and National Archives in a hearing titled, “Washington Metropolitan Area Transit Authority: Is There a Security Gap?”
