The MBTA South Coast Rail Project will restore rail service between Boston and southeastern, Massachusetts. South Coast Rail will be built in phases. Phase 1 service will provide a one-seat ride by extending the existing Middleborough/Lakeville commuter rail service from Boston to Taunton, Fall River and New Bedford. It will deliver service to the South Coast late in 2023. Construction entails track upgrades, the creation of train layout space, the installation of signal systems, and four new stations. The layover facility for train storage, located in New Bedford at Whale’s Tooth, is adjacent to an existing rail storage area. It will have 6 tracks where trains will be stored before beginning service daily and after ending service. This contract includes work on 24 miles of track, 12 interlockings, 11 culverts and additional systems and infrastructure. The project includes the installation of new rail, ballast, and sub ballast; raising the track in some locations; and installing ballast vibration mitigation. GM2 is providing construction engineering support for survey and developing 3D surface modeling. The surface models are being developed for rail roadbed components and final grading throughout the project which will guide earth moving equipment for final construction.
