Hi, on Saturday night there was an incident on the train we were on that resulted in the Beverly Police coming and removing a passenger. What determines if the MBTA police are called or local police? And, I assume local police have full jurisdiction on MBTA trains?
I've never seen TPD respond to anything on the commuter rail outside of Boston. I would assume this is because at the far fringes of the CR system the nearest TPD officer could be an hour away.
I've seen local police do everything from assist with a medical emergency, to remove unruly passengers, to flag crossings.
