MBTA news, delays and slow zones

Red Line delays were a bit less severe than in recent weeks, with round trips delayed around 50-55 minutes because of speed restrictions, according to data analyzed by Transit Matters.

• But things on the Orange Line got worse this week, with delays lengthening to around 15 minutes per round trip compared to the sub-10-minute delays seen earlier this month.

Of note: Shuttle buses will replace Red Line service between JFK/UMass and North Quincy after 8:45pm Monday through Thursday.

• The Orange Line will bypass Haymarket in both directions and the Green Line won't run between North Station and Government Center this Sunday for demolition work.
• The Green Line extension between Medford/Tufts and Government Center, including the Union Square spur, will be closed this weekend.
