Wrong railing from Wellington to Sullivan is what they do. Trains can't cross over at Community, because the truck pad is between Community and Sullivan. Workers need the truck pad to move equipment and materials onto the ROW.
Re: Silver Line to Chelsea (Study Meeting)
When it's time to replace the dual mode buses, the T should order Seattle-style hybrids. They have a special "hush mode" where they can run solely on battery power at 15 mph. There would be no need for that lengthy process of raising the trolley...
Interestingly, the 28 now has 24 hour service on Saturdays and Sundays, though only in the inbound direction. The last bus departs Mattapan at 2:45 AM and the first bus departs at 3:20. That's only a 35 minute gap in service.
