Transit Police report arresting an Everett man on a charge of open and gross lewdness on the Malden Center commuter-rail platform after, they say, people waiting on the neighboring Orange Line platform turned to see where some grunting sounds were coming from around 7:25 p.m. yesterday. Read more.

Sharon Machlis grabbed a couple of months of commuter-rail performance data and created a site that lets you see on-time performance for lines and trains.

MassDOT reports people who normally ride the Needham Line on Saturdays will have to find another way to get around between Aug. 3 and Oct. 12 to let workers install a "positive train control" system that will make the line safer by keeping trains from going too fast and reducing the odds they might crash into each other.

Preparation for the new system has included cutting down trees along the right of way in recent months.

Laura Wareck is among the jammed-in riders at North Station, where a Lowell Line train seems to have left this mortal coil.

Meanwhile, the Red Line is busy Red Line'ing.

Dave Vittorini shows us just how close commuters can jam themselves together, in this photo taken around 4:45 p.m. at South Station, where some Red Line commuters tried using commuter rail instead. Read more.

Keolis reports:

All trains on the Needham, Franklin, Fairmount, Providence/Stoughton, Middleborough/Lakeville, Kingston/Plymouth and Greenbush lines are currently experiencing 15-25 minutes delays due to a signal issue.

The trains have been late, delayed or outright cancelled for the past week and a half...this morning coming from Salem was ridiculous! And, why is that the GPS on most trains suddenly goes dark when the trains are late, delayed or cancelled? Is Keolis playing games with their 'on time' performance metrics?

But fear not, the latest fare increase doesn't hit until July....aaargh

A disgusted citizen files a 311 complaint about the new black splotches on his or her car after driving under the train bridge over East Cottage Street in Dorchester:

There is tar dripping from the bridge. It dropped on my car and ruined the hood and roof.

Alon Levy ponders the oddity that is the Providence Line: Completely set up for more reliable electric trains, yet the T - which owns the tracks from South Station to the Rhode Island line - continues to run diesel locomotives on it.
