The MBTA yesterday announced its latest round of weekend shutdowns aimed at upgrading various things it didn't upgrade during last year's month-long Orange Line shutdown and to account for the continuing demolition of the Government Center Garage, which will also affect the Green Line. Read more.

The MBTA says it's resuming Red Line service to Alewife starting tomorrow - but that the trains will only be reachable via the Russell Field entrance, about a two-minute walk from the garage, where somebody rammed out a five-ton concrete barrier that fell onto large windows overlooking the main station entrance, which remains shut.

Transit Police have put out a BOLO for a man they say punched a 62-year-old woman after she said "excuse me" as she tried to walk past him in the concourse between the Orange and Red lines at Downtown Crossing around 2 p.m. yesterday.

If the alleged puncher looks familiar, contact detectives at 617-222-1050.

Updated with new shutdown time.

The MBTA reports workers overnight removed the five-ton concrete barrier a guy in a Civic knocked loose from the Alewife parking garage yesterday but that the station will remain shut until engineers can figure out how to create a safe passageway from outside to the fare gates - which could take the rest of the week.

The MBTA had to stop the Red Line between Broadway and JFK/UMass this morning because of "a downed fence blocking the track area" near Andrew Square. And then there were the disabled trains it had to push/shove/somehow remove from the tracks on the Braintree branch.

The MBTA reports southbound delays of up to 15 minutes on the Red Line due to a train suffering a coronary at Porter Square.

The MBTA reports things are back to what passes for hunky dory on the Red Line now that they've disposed of a train with a "mechanical problem" at Fields Corner, so the governor should have no problems as she takes a ride on the Red Line at 12:30 to show her concern about T issues - from Park Street to South Station, from which she is supposed to walk to the T operations center on High Street, which, based on the continuing extra time between trains on the Red Line, is still understaffed.

An inbound Red Line train at Andrew had to be taken out of service when it began to get more than just a tad smoky. The T reports: "The train had an issue with the heating/AC unit on top of one of the cars. The unit has been shut off and the train was sent to the yard," no doubt to think about what it had done.

The Globe reports the T hasn't gotten a single new subway car in seven months now. CommonWealth reports on some of the numbers - and says the Chinese company the T hired wants it to pay for the added costs of Trump-era tariffs on Chinese goods, which the T could balance by implementing the $500-a-day penalties the contract allows for late deliveries.
