Has anyone else noticed the plethora of large grey mettle boxes that seem to be springing up in the system? What are they for? Possibly communications? I have seen them at Prudential, Copley, and Boylston so far..
Someone noticed this on the old board at the Kendall station on the Red Line, as well as new conduit at the Porter Sq. station.
We were guessing, but we thought that perhaps this had something to do with infrastructure for an Automated Fare Collection System.
Anyone else?
