At South Station on the Red Line.

A Lawrence man faces arraignment today on charges of assault and battery and indecent exposure for an incident around 7:25 p.m. on Saturday at the Park Street T stop.

Transit Police report that Saud Alradada, 21, of Lawrence, went up to a T worker standing by the fare gates and punched her in the shoulder for no good reason:

It's a Monday-morning slog on the Red Line inbound from Braintree, thanks to signal issues.

Meanwhile, an Orange Line train refused to get out of bed at Oak Grove.

Around 7:30 p.m., H reported:

On a dark Red Line train stuck between Kendall and Park...

This morning at 7:20 am, a northbound Red line train dies on the Braintree branch

right before it left its terminal. "No announcements were posted and said", said

one rider at wollaston sta. waiting almost half-hour for the train. Countdown clocks

kept jumping up and down 10-9-12-10-11 mins. T riders wondered whether the

Red Line was playing the "Follow the Leader" game and thought to decide to play

it for another 45 mins.

Firefighters are on Elm Street in Dorchester, trying to contain any fluids that might be leaking from a T maintenance vehicle that fell off the Red Line around 7 p.m.

A T spokesman reports:

A piece of equipment crews have been using all weekend for track work on the Dorchester branch of the Red Line slid down a hill today. Operator of the equipment had no visible injuries but was taken to the hospital as a precaution. The cause of the accident is under investigation. Buses have been replacing train service in that area all weekend to allow crews to perform the track work.

Transit Police report charging a Hub man with shtupping himself on a Red Line train last night while making lewd comments to two women sitting across from him.

More specifically, Richard Johnson, 48, of Boston, "had his penis out of his pants and was masturbating/fondling himself," police say, adding he got off at Downtown Crossing.

Johnson is scheduled for arraignment today in Boston Municipal Court on a charge of open and gross lewdness.

Innocent, etc.

Or maybe there's a sentimental reason. Whatever, yes, that's a wedding party on the Red Line. Jason Robert got a snapshot of the lucky couple and their party this afternoon.

He reports they got on at Harvard and were still on the train when he got off at Park Street.

Paul MacMaster wondered:

Maybe Sob Story Guy will offer a toast...for the price of a train ticket to Worcester.

Just to switch things up a bit, a Red Line train died in the middle of the day, at South Station, leading to what the T describes as "severe" delays. At 1:22 p.m., Flea reported:

30 minutes and I haven't made it from Wollaston to North Quincy yet.

There was a disabled train then a disgruntled moron who started walking on the tracks.
