The road channel is the primary frequency, all trains/tracks monitor this channel. Defect detectors are on the Road channel as well. To call the dispatcher, crews select the Dispatcher channel for the area they are in, 'Ring up' the dispatcher using DTMF codes, and await a reply on the dispatcher channel, and they will converse there.

The MBTA is in the process of building a new radio system. The system is being built by MA/Comm and reportedly will be an EDACS system with Pro Voice Digital Modulation. There have also been rumors that the system will be EDACS with analog voice. All MBTA operations, but not commuter rail, including police will be moved to the new system. It is expected that some UHF capability will be left in the tunnels for use by other public safety agencies.
Pan Am Railways owns and operates the Springfield Terminal Railway Corp., Boston & Maine Railroad Corp. and the Maine Central Railroad Corp. It owns and operates trackage in CT, MA, ME, NH, NY & VT. Dispatch Office is in North Billerica, MA.
