Hearing through the grapevine that the 1600s are cycling through PTC work which is being done on the South Side, tying up somewhere between 3-6 cars. Hence the need to move other control cars north. Might we start seeing 1600s as actual control cars south?
1631 is currently leading a 7 car set Northside. There also seems to be an all-MBB set roaming around? I saw one rolling by a week or two ago while waiting for the orange line at Sullivan. And yesterday, 1512 was leading a Fitchburg line train.
I noticed Cameras and possible microphones in car 835 today. They were to the left of the electronic display. Bigger and much more visible than the ones that were on the Passenger count train.
Anyone know their purpose? Security surveillance or a new look / more cars being set up for passenger counts?
