The Green Line has always stood apart from the other three T lines - and only partly because it's the only trolley line. Which other line would suffer service delays due to turtle ? Here are some highlights from the Green Line, 2012 edition:
A Newton man was charged with onanism at Beaconsfield  - he allegedly stood on the platform opposite this ad:
A woman was robbed at riflepoint  at Chestnut Hill.
State officials broke ground  for the Green Line extension - the same day the entire line ground to a halt.
The T inaugurated bananaphone service  on the Green Line.
Green Line tracks caught fire  at Lake Street:
Sob Story Guy refused to let a trolley leave Boylston until somebody gave him money. 
Kenmore Station was shut for a melee  after a concert at the House of Blues:
A woman irate at some guy she thought was giving her the eye whipped out a pocketknife and began swinging it at passengers  on a Riverside trolley.
A trolley coming into Boylston plowed into a trolley stopped there, injuring three dozen (including the operator of the hit trolley ); the driver of the plowing trolley was fired after T officials learned he came off an overnight shift  at a second job only three hours before he started his Green Line job.
An E trolley and a Ride van collided along Huntington Avenue .
An owl was removed from the entrance to Park Street .
Two trolleys proved unable to occupy the same space  at Brigham Circle:
The T began sending trolleys to an upstate-New York plant for renovations  - via flatbed trucks. The T announced plans to shut Government Center for two years for a major overhaul  - which will presumably include working fare gates  and escalators that don't catch on fire .
A Medford man was nabbed cutting and stealing signal cables  at Brookline Village - allegedly, of course.
Mike Dukakis continued to use the Green Line .
A man slipped under a trolley at Haymarket ; riders alerted the driver, who kept the trolley still until he could be removed.
A man proved you can always find a seat on the Green Line - if you're limber enough :
A man who allegedly exposed his junk to a woman on an outbound B train claimed jostling on the crowded trolley made his shorts fall off .
A woman changed all of her clothes  and applied lotion liberally on an outbound C trolley.
