Bus rapid transit
In 2012, the Metropolitan Transportation Authority released an analysis of transportation solutions for the North Shore, which included proposals for the reintroduction of heavy rail, light rail, or bus rapid transit using the North Shore line's right-of-way. Other options included transportation systems management which would improve existing bus service, and the possibility of future ferry and water taxi services. Bus rapid transit was the preferred option for its cost and relative ease of implementation, which would require $352 million in capital investment. The analysis evaluated the alternatives according to their ability to "Improve Mobility", "Preserve and Enhance the Environment, Natural Resources and Open Space", and "Maximize Limited Financial Resources for the Greater Public Benefit". Since 2015, the MTA has been planning to utilize the old right-of-way for bus rapid transit. The 2012 plans included the West Shore/Teleport extension, which would add seven new stations, including two new stops in the vicinity of the former Arlington terminal. In July 2018, the MTA indicated that it was retaining a consultant to advise on an environmental impact assessment for the bus rapid transit line on the North Shore Branch.
