Boston Police report arresting a pair of East Boston teens on charges they tried to slice a guy up at the Government Center T stop around 4:20 p.m. today.

The victim, in his late teens or early 20s, was slashed in the arm, but is expected to survive.

Police charged Juan Chavez, 18, of East Boston, with assault and battery with a dangerous weapon and affray. Another teen, 15, was charged with disturbing the peace and affray. Both will be arraigned Friday in Boston Municipal Court.

Brookline Police report on an attempted armed robbery around 10:30 p.m. yesterday near the Winchester Street trolley stop on the C line:

The victim states that she was walking from the T stop when a man approached her from behind, the suspect used the corner of his jacket to cover his face, kept his right hand in his pocket and demanded money from her. She showed him that she did not have any money. The suspect was last seen on the corner of Fuller St. and Winchester St. No weapon was shown, but the suspect hinted that he had one in his pocket.

The suspect is described as a Hispanic male, mid 20s, 5'5", wearing dark pants and a dark waist-length rain jacket with a hood.

70 passengers on board D train; none hurt in Friday-evening incident.

A story for our times, involving a little boy, a mean seat-stealing lady and an entire trolley of onlookers.

Maybe it's just as well the MBTA and its predecessors have spent the last 60 years or so taking out trolley lines; imagine if there were more streets like Huntington Avenue by Mission Hill where Massholes got to scream and curse out trolley drivers for daring to stop to let passengers off?

... This guy is literally leaning out the window, screaming at the driver of the first [trolley] car. I of course had my window cracked to hear every sweet word of invective this moron was letting loose.

And then had a good chuckle because just ahead of the first car, just past the intersection, was a cop car. And as we all started moving again, guess who was getting pulled over? ...

Fire in the hole, on the tracks between Boylston and Arlington Friday afternoon:

... FD had a hard time verifying that the power to the trains was turned off before they could go into the tunnels: lots of conflicting reports about whether or not the T had turned it off. ...

Some of them, anyway, the Globe reports:

... At North Station, where MBTA officials have spent more than $262 million renovating the station, water poured in through the ceiling. ...

At North Station, however, T official say the problem is due to ongoing construction of a nearby building.

Paul Levy, CEO of Beth Israel Deaconess Medical Center, posts a complaint from an employee who takes the Green Line and a bus between Brookline and Beth Israel's Needham campus: Those "free" transfers the MBTA promised when they raised rates have a time limit built in.

... Apparently, your CharlieCard is time-stamped when you first get on the trolley line, and if the time you enter the bus is more than a certain number of minutes afterward, the discount doesn't work. Ditto on the return trip. A bus driver told this passenger that the second ride has to begin within 20 minutes of the first ride. ...

As he notes, that makes the transfer policy useless if, oh, your connecting bus is late or runs infrequently. And he's left scratching his head wondering why the MBTA would do this.

MBTA police say violent and theft-related crime in the transit system dropped 10% last year, but that non-violent crime, such as public drunkeness and lewdness, vandalism and mouthing off (a.k.a. "simple assault") went up 12%.

In terms of percentages, the Blue Line was the most peaceful line, barely beating out the Green Line. Surprisingly, commuter rail had almost as many violent incidents per 100,000 riders as the Orange Line, although in both cases, the odds of getting attacked or robbed were still fairly small (0.45 incidents per 100,000 riders on the Orange Line; 0.41 on commuter rail).
