One of the BMT radio consoles formerly used at Command Center is   
   on display at NYTM, Brooklyn.  It was part of the "crisis" exhibit.   
      
   Each radio channel key has a bunch of colored indicator lamps associated   
   with it.  There are also keys marked "voting mute", whatever that means.   
      
   I think when a motorman made a radio call, the cosnole sensed it   
   and seized a channel and lit a lamp for the dispatcher to answer.   
   Anyone know how the radios worked?   
      
   Some channels had a single key, but most had two keys.  The keys   
   themselves may have lit up when in use.   
      
   There were "all call" keys.   
      
   There was a larger key marked 'transmit'.  Originaly painted in red, all   
   the paint was worn off.   
      
   I believe the system was installed circa 1967.  Before that, crews   
   had to climb down and use a wayside telephone.  Now they use something   
   else.   
      
      
   There is also a model 28 Teletype, used for messaging to the bus garages.   
      
   Downstairs, car #8013 is on display.
