The Orient Heights carhouse was repurposed as a casket factory. It was destroyed by a fire on March 15, 2019. The right of way from Byron Street to Tomahawk Drive was acquired by the Massachusetts Port Authority for the expansion of Logan Airport. The right of way through Jeffries Point is privately owned; the tunnels are intact though their north ends are buried. Part of the right-of-way between Logan Airport and the Blue Line section was used for a U.S. Navy oil pipeline in the 1950s.
