The Mattapan High Speed Line is old and difficult to maintain. MBTA is currently looking at future options on how to maintain transit service along that corridor. As far as I know, there are 4 options:
- Do nothing, and continue to maintain the PCCs.
- Replace with a modern light rail vehicle.
- Replace with bus service.
- Extend the Red Line
I haven’t seen much discussion on that last option, so this post aims to be a comprehensive view on what it would look like. It’s a mix of collecting others’ discussions and some original ideas.
I think it’s a good idea, so I talk pretty glowingly about it, but this is meant to inspire conversation rather than convince you that it’s the best plan.
