Subway Systems:
The first subway line was built in 1909 to connect the Russell Senate Office Building and the Capitol. The systems are open to the public insofar as the public had to be escorted by staff members with proper identification during a tour of the Capitol. But during votes the subway is only meant for Congressional members only. Also since the terrorist attack on September 11, 2001, restrictions have been placed for people using the Senate subway between the Hart and Dirksen buildings.
