The Greenbush Line opened for regular passenger service on October 31, 2007, with 12 round trips on weekdays and 8 on weekends.
 Some minor construction projects, like the erection of fencing in populated areas, lasted into 2008.
 The 7 stations built for the line are similar in construction; each has a single 800-foot-long high-level side platform, serving a single track.
 Each station has 200 to 500 parking spaces, except for Greenbush, which houses 1000 spots in order to serve commuters driving from Hanover, Norwell, Marshfield, and Duxbury.

By 2010, despite predictions of 4,200 inbound passengers a day (or 8,400 total daily one-way trips) riding the train by three years after its opening, the MBTA said that ridership was only half that.
 The ridership numbers were down from 2009, when some 3,081 inbound riders (6,037 total trips) were recorded.
 These passengers were also more likely to have switched to the train from the MBTA commuter ferries, rather than the predicted car users.
Ridership increased 40% between 2012 and 2018, with 6,114 total daily trips in a 2018 count.

Starting on April 30, 2011, weekend service was suspended to allow replacement of faulty concrete ties with wooden ties on the Old Colony mainline.
The Greenbush branch itself, which was constructed with a different order of ties, did not need tie replacement.
Weekend service resumed on December 24, 2011.

On March 28, 2012, the MBTA announced that Greenbush Line service would no longer operate on weekends, as with the Needham Line and Plymouth Line.
The move came as a part of fare increases and service cuts in order to close the agency's operating budget shortfall for the following year.
Weekend service was eliminated beginning July 7, 2012; weekend service was kept for the first week of the new fiscal year to allow for service on the July 4th holiday.
On October 7, 2014, the MBTA announced the return of weekend service on the Greenbush Line, as well as weekend service on the Plymouth/Kingston Line and Saturday service on the Needham Line.
The restored weekend service began on December 27, 2014.
