The signal improvements will be achieved by (1) replacing the wayside signal cases with new CIH’s (fabricated by the MBTA, installed by the Contractor), (2) providing two new CIH’s for the Reservoir and Grove Street interlockings, (3) providing approximately 6.5 miles of new wayside aerial cable and cable support system on existing catenary poles, (4) providing all wayside signals, pushbuttons, power and hand-throw switch machines, and (5) providing all other ancillary signal equipment and other elements necessary for a fully functioning system as shown on the contract plans. Track improvements consist of the renewal of approximately 24,000 feet of mainline track, replacement of special trackwork, platform edge reconstruction, and grade crossing reconstruction.
