It's Cambridge Shred Day tomorrow at the Central Square post office.

Cambridge Day reports on efforts to build a crowdsourced "laser-cutting, laser-engraving and 3-D printing workshop where customers can come in and etch pretty much any design onto any object without having to buy their own gear" in Central Square.

Danger!awesome.

Cambridge Day reports the location where the old club was set to return to now looks set to become a pet store instead.

Cambridge Day reports the owner of the Middle East in Central Square wants to buy the building the club is in. To pay for the purchase, he says he'd want to add four or five stories of residential units above the club.

Cambridge Police report a plainclothes officer spotted a man appearing to be packing a gun around 9:30 p.m. on Monday. When the officer noticed the man and another man engage in a street transaction of some kind on Mass. Ave. near Sidney, he identified himself, an act to which the pair reacted by trying to run away, only they proved unable to outrun Cambridge officers, police say:

An inbound Red Line train that left Harvard at 11:54 this morning finally made it to Central at 12:37 p.m. - pushed there by another train - the MBTA reports.

Christian J. Ternus tweets:

Just got off Red Line train that caught fire. Train filled with smoke.

MBTA operator lost her keys and couldn't get into cab to call for help. Operator told passengers not to ride Red Line in bad weather. "MBTA doesn't spend enough to make it safe." Passengers were having asthma & panic attacks. MBTA op described this as "passengers complaining." Train was *On Fire.*

MBTA spokesman Joe Pesaturo says there was no fire on the train, adds:

The train operator did not lose her keys nor make any safety-related announcements on the intercom. The tweet was in reference to another MBTA employee who had boarded the train to investigate the cause of the power problem. The employee attempted to open a door at the end of a Red Line car, but was unable because she did not have a key. This employee made some comments to another employee that were picked up by one or more customers (one of whom then tweeted). Both employees have been identified and both have submitted statements to supervisors. The head of the Red Line is investigating.

UPDATE: The T reports service resumed around 2:10 p.m., with, of course, residual delays.

Ruddy S. reports a broken rail. The T says it's now busing between Kendall and Harvard.
