Ansaldo STS USA says it has been awarded an $11.9 million subcontract agreement with Mass Electric Construction Co. as a part of the Washington Metropolitan Area Transit Authority’s (WMATA) “Rehabilitation of Red Line MetroRail System—Dupont Circle to Silver Spring” project.
Ansaldo STS USA is responsible for upgrading the Automatic Train Control system, which includes replacing switches and signals and upgrading eight interlockings from mechanical relays to Microlok®II solid state controls. Ansaldo STS USA is also responsible for replacing the Emergency Trip Stations, Public Address system, and Closed Circuit TVs at stations with related communications design.
"This project complements our May 2009 contract award at WMATA’s Silver Spring location in that this work connects the two sections and employs similar technology,” said Mark Cirucci, vice president customer operations for Ansaldo STS USA. “We are proud to support WMATA’s commitment to quality systems and the safety of their passengers, employees, and community.”
