Brandon Merritt reports from a Worcester Line train stuck about 2,000 feet past Yawkey. There's a switching problem of some sort that requires some guy from CSX to come in and fix it - which he finally started doing 90 minutes after the train stopped. Some people are abandoning the train and walking down the tracks because the train crew won't back the train up to the station. The smokers on the train are lighting up. The toilet is disgusting. And the only video he has on his iPhone is a Nick Jr. show.

UPDATE AT 8:37 P.M. Merritt tweets his train, the 6:35 local, has started to move, slowly - as has the 6:15 express in front of his train.

The T announced today its ban on employee cellphone use - and possession - has been extended to commuter-rail, ferry and Ride vehicles, as well as operators of private buses under contract to the T.

Krissy reports she rode commuter rail between Newton and Boston yesterday and wasn't asked for a ticket in either direction.

Passengers being told to take the Blue Line to Wonderland to get a shuttle bus to Lynn. Did a train hit somebody? Yes, in Everett.

Apparently, it's a fun new game: Try figuring out if the trains are really going where the signboards say they are. Guess correctly and you win a trip to your destination. Make the wrong choice and you get to get off at the next stop and take the Orange Line back to North Station for another try.

The MBTA informs us of a renewed push on its "See something, say something" campaign tomorrow morning:

At dozens of stations around the nation's fifth busiest public transportation system, MBTA Transit Police will be joined by bus, subway, and Commuter Rail personnel in talking with customers and distributing tens of thousands of the MBTA's Transit Watch pamphlets that encourage people to report:

An unaccompanied bag or package in a remote area
Any passengers behaving oddly
A group operating in an orchestrated or rehearsed manner
Suspicious odors, fluids, or other substances

At Back Bay Station, Boston Mayor Thomas Menino, Boston Police Commissioner Edward Davis, Suffolk County District Attorney Daniel Conley, MBTA General Manager Daniel Grabauskas, Transit Police Chief Paul MacMillan will hand out the pamphlets to commuters.

Noah Bierman reports a Globe analysis that peak morning trains are late more often than the reported numbers for the lines.

Apparently the retraining was necessary because too many conductors forgot about it in the press of all their other duties such as, um, er, I dunno, opening doors at stops?

MBTA proposes elimination of weekend commuter-rail service, cuts in the evening.

A rider on tonight's 6:15 p.m. train on the Kingston/Plymouth Line out of South Station e-mails this report:

Ever wonder what a "switch problem" is? In this case it means that the train stopped just south of North Quincy. Then the train proceeded to back up . . . all the way to the gas tank. The conductor said that we were backing up because we were on the wrong track. I half expected Bugs Bunny to pop out of a hole and say, "Looks like I made a wrong turn at Albuquerque!"
