Around noontime, Kerry Tubbs photographed the line at the CharlieCard store in Downtown Crossing, where dreams go to die all the people whose CharlieCards expired on Friday have to go to get their remaining value transferred to fresh new cards that don't expire until 2021.

Meanwhile, Red Line riders are queuing up in novel places at South Station this afternoon because the traditional stairway down to the subway is shut for repairs. But, Jesse Tokarz reminds us, at least there's still five different coffee shops inside. At least there's a bar now.

When a 24-year-old with a heart condition went into cardiac arrest and collapsed last week, an MBTA worker who knows CPR kept him going until an ambulance could arrive to get him to the hospital.

The T says that Kevin Bossart collapsed, fell down the stairs and struck his head. Station Customer Service Agent Karen Kane rushed to get a co-worker, Tomas Gonzales, who began performing CPR. Gonzales, an MBTA training instructor, doesn't normally work at Wollaston, but was there to help out with issues related to the cold weather.

Bossart's family went to Wollaston today, to thank the T workers:

An inbound train passed to the other side at Broadway; another train developed door issues at Charles/MGH.

Shawn Whitlock reports:

Just took 20 min to go from Broadway T stop to South Station. That's ONE stop. Bravo, MBTA, bravo!

An inbound Orange Line train didn't even make it out of the starting gate at Oak Grove early this morning. Somewhere on the Ashmont branch of the Red Line, an outbound train felt that disturbance in the Force and went over to the dark side.

A Quincy man charged with masturbating on an inbound Red Line train before reaching a crescendo just before Broadway at first denied he was playing his flute, according to the Suffolk County District Attorney's office says.

Just another morning on the Red Line: Shortly after 7 a.m., an inbound train at Andrew gave up the ghost. Not long after, this happened:

And now there is a mouse on the train. And apparently it fell from the ceiling.

Where have you gone, Ms. Penelope?
The Red Line turns its lonely eyes to you
(Woo woo woo)

UPDATE: The Blue Line joined the party shortly before 10 a.m., when a train ascended to Valhalla at Wonderland.

Dead inbound train at Quincy Center would be harshing the mellow of Red Line commuters this morning if they weren't busy concentrating on staying warm. An Orange Line train could only make it to Back Bay before departing this mortal coil, but riders from the north also got to enjoy today's frosty climes. A dead trolley somewhere past Kenmore is causing ish on the Green Line.

An inbound train on the Franklin Line decided Norfolk was too good a stop to pass up. Erich Haberman reports from the train behind that one:

7am at Norfolk now. Train's lights/air are off and we appear to be ramming the disabled train while attempting a rescue.

Meanwhile, at South Station, somebody got stuck in an elevator between the Red and Silver lines.

Well, actually, it's not picking up much at all right now, thanks to a southbound train that decided at Charles/MGH it needed a doctor right away.

UPDATE: Arrest made.

Transit Police report they are looking for the guy in red in this video on charges he attacked and robbed a disabled man around 11 p.m. on Saturday in the Andrew busway.

As Rich Davey predicted yesterday, the T has been having problems with the cold this morning. Red Line trains kept dying south of the city, leading to massive delays and eventually bustitution.

Several commuter-rail lines had weather-related delays as well, although, ironically, the Needham Line ran on time.
