Jelaskan Hours of operation dari Massachusetts Bay Transportation Authority

Traditionally, the MBTA has stopped running around 1 am each night, despite the fact that bars and clubs in most areas of Boston are open until 2 am. Like nearly all subways worldwide, the MBTA's subway does not have parallel express and local tracks, so much rail maintenance is only done when the trains are not running. An MBTA spokesperson has said, "with a 109-year-old system you have to be out there every night" to do necessary maintenance. The MBTA did experiment with "Night Owl" substitute bus service from 2001 to 2005, but abandoned it because of insufficient ridership, citing a $7.53 per rider cost to keep the service open, five times the cost per passenger of an average bus route.

A modified form of the MBTA's previous "Night Owl" service was experimentally reinstated starting in the spring of 2014 – this time, all subway lines were proposed to run until 3 am on weekends, along with the 15 most heavily used bus lines and the para-transit service "The Ride".

Starting March 28, 2014, the late-night service began operation on a one-year trial basis, with service continuation depending on late-night ridership and on possible corporate sponsorship. , late-night ridership was stable, and much higher than the earlier failed experimental service. However, it is still unclear whether and on what basis the program might be extended past its first year.  The extended hours program has not been implemented on the MBTA commuter rail operations.

In early 2016, the MBTA decided that Late-Night service would be canceled because of lack of funding. The last night for late-night service was on March 19, 2016. The last train left at 2 a.m. on March 19, 2016.

In 2018, the MBTA further tried "Early Morning and Late Night Bus Service Pilots".

In June 2019, a year after the trials the board voted to make some changes to the schedule which would allow for further late night service to be incorporated long term
