Jelaskan South Coast Rail dari MBTA Commuter Rail

The South Coast Rail project is under construction to extend service to the South Coast cities of Taunton, Fall River, and New Bedford, which were last served by commuter service in 1958. A full planning process was held from 1990 until its suspension in 2002. Planning restarted in 2007, with environmental documentation completed in August 2013. Plans were modified into two phases in 2017 due to an increase in costs. Phase I is under construction to run diesel service beginning in 2023 as an extension of the Middleborough/Lakeville Line via the Middleboro Secondary. Phase II, planned for 2030, would extend the Stoughton Branch of the Providence/Stoughton Line over a reactivated line with electric service.
