It is very rare to see a Keystone with two locomotives and it is almost always due to a shortage of Metroliner control cars. Usually it is two Sprinters bookending a set of Amfleets with a cafe car in the middle for Wifi. It is the route you would expect to see problems IMO... some of those trains are doing quazi-commuter runs (less than 10 miles between many stops).
Shortage, in most cases this is due to the cab car malfunctioning. In my limited experience and from what I see on YouTube, there seems to be a steady amount of Keystones running with ACS-64s on both ends, with one coupled to a Metroliner Cab Car. I rode one to NYP that was nearly two hours late, then passed another Keystone with two Sprinters. Again, I don't ride Keystones or Amtrak super often, so my empirical data might not be as keen as others. It's not a frequent occurrence, but not rare as say spotting the Corridor Clipper or something like that.
As evidenced by my username, I'm a Man who's a fan of trains in the Northeast US.
