MBTA Green Line Type 8 is a Light Rail vehicle that was built by AnsaldoBreda for the Massachusetts Bay Transit Authority. The cars were constructed from 1998-2007 and replaced all remaining Boeing LRVs Type 6s. Most of these cars currently share models with the Kinki Sharyo Type 7s at the same time. They run on the B, C, D and E lines.[1] The MTBA currently runs 96 Type 8 vehicles which will be progressively joined by 24 Type 9's from 2017-2019.[2]

History/Problems

In 1996 The MBTA requested AnsaldoBreda to made 96 new cars for the Green Line. The MBTA started running these cars in 1999, but they were very prone to derailment because of an incorrectly sized wheel axle and had to be taken out of service before returning in 2006.[1] According to MBTA Chief Operating Officer Jeff Gonneville they present a 'maintenance challenge'. [3] They started tethering the Type 7s and Type 8s together to work with each other and making the wheels on the cars the same as the Kinki Sharyo Type 7s.[1] This was criticized for making rush hour commutes unreliable.

In October 2016, Boston Globe reported that the MBTA Green Line had the most derailments on this model.[4]

Features

Features include automated announcements and 75% low floor accessibility for wheelchairs and white interior walls.[1] Some of these features were later rolled out on the Kinki Sharyo Type 7s.[1] The pre recorded announcements were made by the voice Frank Oglesby who retired in August 2016 and they were criticized for having software bugs and sometimes failing to work. The traction systems in these cars are about the same thats used in the NYC Transit MTAs R142A, R188 and R143 trains.

Criticism

These trains were criticized for having software problems with the pre recorded announcements and for working with the Kinki Sharyo Type 7s causing slow and unreliable rush hour commutes. Their folding doors are also not as reliable as sliding doors, and their low clearance over old tracks may be increasing risk of derailments.[5]
