   So... they're going to catch up to where the Class 1 railroads have been   
   for a decade or so?

   I'll bet you $100 that the Metro North autonomous system not be installed   
   on every train; that they will be put on a only a few cars; that they will   
   not actually measure the track but will actually be accelerometers to   
   measure "ride quality"; and, In general will work exactly the same (and   
   probably be bought from the same vendor) as the ones currently installed on   
   dozens if not hundreds of freight locomotives.
